AS13100 Executive Overview Part 3: The Need for AS13100

2021-03-02
The AESQ wants to simplify, harmonize and create a common language through AS13100. Although there's already an aerospace standard called AS9100, the engine manufacturers have had to put supplemental requirements around this because they're expected to flow down the requirements from their regulator, the customer, and their own business. Because of the criticality of the engine and the potential consequence of any non-conformance, many of the requirements are far more stringent than you would get on any other commodity on the aircraft. The purpose of AS13100 is to take these supplemental requirements and build it into a single standard.

Real-world Evaluation of National Energy Efficiency Potential of Cold Storage Evaporator Technology in the Context of Engine Start-Stop Systems

2020-11-09
National concerns over energy consumption and emissions from the transportation sector have prompted regulatory agencies to implement aggressive fuel economy targets for light-duty vehicles through the U.S. National Highway Traffic Safety Administration/Environmental Protection Agency (EPA) Corporate Average Fuel Economy (CAFE) program. Automotive manufacturers have responded by bringing competitive technologies to market that maximize efficiency while meeting or exceeding consumer performance and comfort expectations. In a collaborative effort among Toyota Motor Corporation, Argonne National Laboratory (ANL), and the National Renewable Energy Laboratory (NREL), the real-world savings of one such technology is evaluated. A commercially available Toyota Highlander equipped with two-phase cold storage technology was tested at ANL?s chassis dynamometer testing facility.

Development and Industrialization of a Laser-Based Hard Material Coating System for Brake Discs

2020-11-09
Fine dust emissions caused by road transportation are being investigated and discussed in detail by governments and vehicle manufacturers. Brake abrasion contributes to a significant extent to this ambient air pollution. There are different approaches to minimize this brake disc abrasion, one of the most promising is the coating of the friction surface with wear resistant layers, i.e. with metal matrix composite (MMC). One coating technology, the extreme high-speed laser material deposition, has proven to be extremely effective, especially in combination with appropriately adapted brake pads. In detailed investigations with various brake disc manufacturers, HPL Technologies in Aachen, Germany, examined influences on the quality such as reliable corrosion and wear resistance.

Impact of Phenolic Resin Type on the Performance of Newly Developed Friction Materials for Vehicles with Regenerative Braking

2020-11-09
Automotive industry is undergoing a paradigm shift towards vehicles with alternative power. The sales of electric vehicles have increased by over 165% over the past 2 years in the United States [1]. With government incentives coupled with the decrease in battery cost, the trend seems to continue. As the friction brake accounts for about 5 to 30% of total braking in electric/hybrid vehicles, this also warrants for more research into the development of new lightweight, wear resistant, and sustainable friction materials also for reviewing the existing testing procedures. Phenolic resin is typically used as binding material in majority of the current brake friction materials. Numerous authors demonstrated that the type of phenolic resin has effect on properties of brake pads [2].

Enclosure-in-Chamber Setup to Achieve Near-Zero Background Concentrations for Brake Emissions Testing (SAE Paper 2020-01-1634)

2020-11-09
Measuring brake emission continues to be a challenging non-standardized task. Extensive research is ongoing and as seen in the work in progress presented at SAE Brake Colloquium and PMP meetings. However, open items include how to achieve lower background concentration and how to design the brake enclosure. A low background concentration is essential as brake events are short and some emissions are in the range of reported background levels. Hence these emissions are difficult to distinguish from the background level. Even more critical, a high background concentration can result in a wrong particle number emissions value, either overestimated, background counted as emissions, or underestimated, background level subtracted, and low emission events no longer detected and counted. Reducing the background level to less than 100 #/cm3 appeared to be quite challenging.

Ultraviolet and Titanium Dioxide Based Photocatalysis HVAC System to Eliminate COVID-19 for Occupant�s Safety & Health in Automobiles

2020-11-09
In a photocatalytic air purifier system, the catalyst that cleans the air is typically titanium dioxide and it is energized by ultraviolet (UV) light. UV is the short-wavelength light just beyond the blue/violet part of the electromagnetic spectrum that our eyes can detect. This shortwave-length light has much more energy than ordinary, visible light�and exactly the right amount of energy to get titanium dioxide excited. Titanium dioxide is a semiconductor that covers the filter surface. Just a thin film of titanium dioxide is required at the filter surface with a substrate. When UV light shines on the titanium dioxide, electrons (negatively charged particles inside atoms) are released at its surface. The electrons interact with water molecules (H2O) in the air, breaking them up into hydroxyl radicals (OH�), which are highly reactive, short-lived, uncharged forms of hydroxide ions (OH−).

Real-World Application of Variable Pedal Feeling Using an Electric Brake Booster with Two Motors (SAE Paper 2020-01-1645)

2020-11-06
A new type of electric brake booster, which can control brake pedal feeling completely with software, has been developed to explore how a brake system can be used to differentiate and personalize vehicles. In the future, vehicles may share an increasing amount of hardware and rely more heavily on software to differentiate between models. Car sharing, vehicle subscriptions, and other new business models may create a new emphasis on the personalization of vehicles that may be achieved most cost effectively by using software. This new brake booster controls the brake pedal force and brake pressure independently based on the brake pedal stroke so that the pedal feeling is completely defined by software. The booster uses two electric motors and one master cylinder. One electric motor controls the pedal force and provides an assist force that amplifies the force that the driver applies to the brake pedal.

Single Discretization for Heat Transfer and Thermal Stress Solving: A Water Jacket Study

2020-11-05
As OEMs look to increase thermal efficiency of their existing engine architectures there is an increased focus on the performance of the cooling system. Water jackets in combination with radiators are the main components to remove excessive heat from the engine block originating from in-cylinder combustion. The temperature reached by the engine block spans from ambient temperature up to 400 K, leading to high thermal gradients and significant failure risks. In this work, the mechanical stresses due to the thermal expansion are evaluated via 3D numerical simulations via an innovative workflow. Typically, solving for the thermal stress, requires two different meshes. In the first mesh, the fluid and solid equations are solved with a finite volume approach. In a second phase, the temperature from the first mesh is mapped onto a second mesh, to allow the thermal stress calculation with a finite element approach, leading to discretization and interpolation errors.

Method for Using Modeling Fidelity in Battery-Electric Vehicle Thermal System Simulations to Optimize Real-World Component Design Targets

2020-11-05
The optimal performance of a battery electric vehicle (BEV) is highly dependent on the thermal environment in which the electric components operate. If the maximum temperature levels for crucial elements are exceeded, there are impacts to the life and reliability of the component. While the standard industry practice is to protect for the worst-case steady-state thermal load condition, this may result in the over-specification of the cooling system. It�s been established that BEVs are impacted by temperature, they are also sensitive to the mass of the cooling system, therefore components must not be over-designed to target extreme operating points. In order to meet these demands, a system level simulation has been developed to analyze the performance of several key electrical components. Detailed component models of the BorgWarner electric motor and inverter are included so that the temperature within these components can be monitored.

Experimental and Numerical Investigation of the Multiphase Flow and Heat Transfer in an Oil Jet Cooled Engine Piston

2020-11-04
The piston temperature has to be carefully controlled to achieve effective and efficient thermal management in the internal combustion engines. One of the common methods to cool piston is by injecting oil from the crankcase underside to the piston under-crown area. In the present study, a novel 3-D multiphase thermal-fluid coupled model was developed using the commercial CFD software SimericsMP+ to study the piston cooling using the oil jet. In this model, an algorithm was proposed to couple the fluid and solid computation domain to account for the different timescale of heat transfer in the fluid and solid due to the high thermal inertia of the solid piston. The heat transfer coefficient (HTC) and reference temperature were mapped to the piston top surface and the liner temperature distribution was also used as the boundary condition. The temperature-dependent material properties, piston motion, and thermal contact resistance between the ring and piston were also accounted for.
