Today's transportation industries are facing multi-disciplinary challenges. The product design and development process challenges often contradict each other, for example cost, weight, quality and performance. A central challenge is the need for cost and mass reduction to compete in the global market, while continuing to meet all new and existing requirements for quality and performance. Accelerated Concept to Product (ACP) Process is a performance-driven, holistic, product design development method intended to create a balance between structure and strength, synchronizing the individual facets of the product development process. It takes advantage of design, material and manufacturing experience using multiple CAD, CAE and CAO tools to reduce product design and development time and costs, as well as to reduce product mass and improve product performance. This three-session web seminar will offer information on how to design a concept model from a clean sheet using a holistic 3G design approach (ACP-3G), where material types and its properties (Grades and Gauges), Geometry (shape), and manufacturing process can work together for the optimum weight and performance.

One of the most important aspects of meeting emission standards is catalyst robustness. Emissions must be met at high mileage, termed “full useful life”, which is 150,000 mi for light and medium duty vehicles under Tier3/LEV3. Catalyst durability is application and system specific. Full useful life aging and correlations to accelerated aging schemes typically include both hydrothermal exposure and chemical poisoning. Robustness tests are designed to exceed the limits of a particular catalyst or filter material and test to failure. New aging schemes and robustness tests are needed when new technologies such as cold start traps for HC and NOx, gasoline particle filters, and SCR coated filters are incorporated into conventional three-way and diesel exhaust systems. This presentation will include a summary of recent emission certifications and publications by various vehicle manufacturers, aging and robustness testing of conventional exhaust systems, as well as a look into the durability of future emission control technologies.

Tough times require searching for things that we can change and making them better. But so often problems are solved with 'band-aids' and not root cause solutions. This approach is getting too expensive and at best only helps companies tread water. To combat these issues and adopt a fresh approach, teams can use the methods and tools of Root Cause Problem Solving to first view problems as opportunities for improvement, identify root causes and implement solutions to prevent recurrence. Benefits include improved quality and customer satisfaction, reduced operation costs, and greater employee knowledge of work processes. This proven 8-step approach to problem solving will help improve operational and financial performance by identifying causes and implementing solutions to significant or recurring problems. This approach to problem solving is used by many major automotive manufacturers.

This paper reviews the correlation concepts and tools available, with the emphasis on their historical origins, mathematical properties and applications. Two of the most commonly used statistical correlation indicators, i.e., modal assurance criterion (MAC ) for structural deformation pattern identification/correlation and the coefficient of determination (R^2 ) for data correlation are investigated. The mathematical structure of R^2 is critically examined, and the physical meanings and their implications are discussed. Based on the insights gained from these analyses, a data scatter measure and a dependency measure are proposed. The applications of the measures for both linear and nonlinear data are also discussed. Finally, several worked examples in vehicle dynamics analysis and statistical data analyses are provided to demonstrate the effectiveness of these concepts.

The automotive industry is constantly looking for new alternate material and cost is one of the major driving factors for selecting the right material. ABT is a safety critical part and care to be taken while selecting the appropriate material. Polyamide 12(PA12) is the commonly available material which is currently used for ABT applications. Availability and cost factor is always a major concern for commercial vehicle industries. This paper presents the development of an alternative material which has superior heat resistance. Thermoplastic copolyester (TEEE) materials were tried in place Polyamide 12 for many good reasons. The newly developed material has better elastic memory and improved resistance to battery acid, paints and solvents. It doesn’t require plasticizer for extrusion process because of which it has got excellent long term flexibility and superior kink resistance over a period of time. Also it has got better heat ageing properties and higher burst pressure at elevated temperature.

The vehicle’s dynamic behavior is influenced mainly by the interaction of four factors: driver, vehicle, road an environment. Under given circumstances, perturbation of these factors can cause degradation of vehicles´ performance; as a result, an accident will take place affecting the vehicle itself, road infrastructure and injury or even death of passenger(s). In order to increase road safety is essential to fully understand the interaction of those factors on vehicle’s dynamic behavior, especially heavy vehicles due to its greater mass, dimensions and potential damage that can cause. This paper presents the effect of road condition on the dynamic behavior of a 3-axle straight-truck based on numerical simulations. Validated commercial software was used. Three different road conditions were studied, namely potholes, longitudinal level differences between adjacent lanes due to repairing process, and different surface friction coefficients also due to road repairing process. For numerical simulations, three standardized maneuvers were taken into account, namely, single and double lane change and panic braking.

In today's world, there are a prominent number of weight & cost reduction projects within the vehicle engineering development activities. Regarding this phenomenon, a complete optimization study is applied to a 4-leaf pendulum leaf spring used in heavy duty trucks by reducing the number of leaves down to 3 together with weight and cost reductions. Leaf spring itself plays a crucial role in a heavy duty truck structure. Because of this purpose, the new designs should withstand all forces like the current design assuring same strength and fatigue characteristics. In other words, it should be lower in price and weight but at the same time strong enough to maintain its durability throughout its life time. This fact brings great responsibility to the development process of the new optimized leaf springs. Hence, a complete optimization process is applied from scratch till the very end which is illustrated in this paper. At the first step of the project, the stiffness of the leaf spring is calculated with an in-house software based on mathematical calculations using the thickness profile of the leaves.

Hydraulic electromagnetic shock absorber (HESA) consists of hydraulic cylinder and check valves etc., by which the high-pressure oil produced by shock absorber reciprocation could be exported to drive the hydraulic motor, so as to drive the generator, and eventually recover the mechanical vibration energy otherwise dissipated by the traditional shock absorber as heat energy. Hydraulic Interconnected Suspension(HIS) can improve the vehicle roll and pitch stablity performance by interconnecting the chambers of the shock absorbers on the vehicle. To integrate both the advantages of HESA and HIS, a new type of suspension system is proposed in this paper, namely Hydraulic Interconnected Suspension system based on Hydraulic Electromagnetic Shock Absorber (HESA-HIS). HESA-HIS has three operating modes: energy-recovery priority mode, driving stability performance priority mode and energy-recovery and driving stability performance balance mode. The working principle of HESA-HIS in the three operating modes is introduced, and the mathematic theory model is deduced with relative automobile theory knowledge.

Design of body structures for commercial vehicles differs significantly from automotive due to government, design, usage requirements. Specifically the design of heavy truck doors differ as they are not required to meet side impact requirements due to their height off the ground as compared to automobiles. However, heavy truck doors are subjected to higher loads, longer life and less damage from events. Past aluminum designs relied either on bent extrusions around the periphery of the door or multiple steel and/or aluminum reinforcements joined to the inner in order to provide the necessary structure. Doors using aluminum extrusions for the peripheries were limited to two dimensional bending for the extrusions resulting in a planar door with limited styling features an opportunity for aerodynamic improvements. Doors with stamped reinforcements and door mounted mirrors require joining the inner and outer structure at the lower mirror mount forcing the use of a division bar to split the glass that impedes vision and drives cost for the extra parts.

Cost reduction in automotive industry becomes a widely-adopted operational strategy not only for Original Equipment Manufacturers (OEMs) that take cost leader generic corporation strategy, but also for many OMEs that take differentiation generic corporation strategy. Since differentiation generic strategy requires an organization to provide a product or service above the industry average level, a premium is typically included in the tag price for those products or services. Cost reduction measures could increase risks for the organizations that pursue differentiation strategy. Although manufacturers in automotive industry dramatically improved production efficiency in past ten years, they are still facing up with the pressure of cost control. The big challenge in the cost control for automakers and suppliers is increasing prices of raw materials, energy and labor costs. These costs construct constrains for the traditional economic expansion model. Lean manufacturing and other traditional Six Sigma processes have been widely utilized to reduce waste and improve efficiency further in the automotive industry.
