This seminar provides an introduction to several critical aspects of heavy truck dynamics. The comprehensive presentation and discussion will begin with the mechanics and dynamics of heavy truck tires, followed by steering dynamics, and finally moves participants into suspension kinematics and dynamics. Starting at the ground and moving up, this seminar explores the important dynamic aspects of each subsystem and how each is related to the overall truck dynamics.

One of the most important safety critical components on cars, trucks, and aircraft is the pneumatic tire. Vehicle tires primarily control stopping distances on wet and dry roads or runways and strongly influence over-steer/under-steer behavior in handling maneuvers of cars and trucks. The inflated tire-wheel assembly also acts as a pressure vessel that releases a large amount of energy when catastrophically deflated. The tire can also serve as a fulcrum, both directly and indirectly, in contributing to vehicle rollover. This seminar covers these facets of tire safety phenomena.

The vehicle-terrain interaction in an off-road environment creates unique challenges for designers of both wheeled and tracked off-road vehicles. Not only should vehicle designers have a working knowledge of the fundamentals of on-road vehicle dynamics, they should also have the specialized knowledge of the vehicle dynamic characteristics found in construction, agriculture, and military off-road vehicles. This one-day seminar concentrates on the basics of off-highway trucks and the differences with their on-highway counterparts.

Understanding vehicle dynamics is one of the critical issues in the design of all vehicles, including heavy trucks. This seminar provides a comprehensive introduction to the fundamentals of heavy truck dynamics. It covers all of the critical subsystems that must be considered by designers and decision makers in determining the effect of various components on heavy truck dynamics. This seminar begins where the tires meet the ground, progressing up through the various components and bringing together the theory and practice of heavy truck dynamics.

While a variety of new engineering methods are becoming available to assist in creating optimal vehicle designs, subjective evaluation of vehicle behavior is still a vital tool to deliver desired braking, handling, and other dynamic response characteristics. In order to better prepare today’s engineer for this task, this course offers twelve modules devoted to key the fundamental principles associated with longitudinal and lateral vehicle dynamics.

Abstract Studies have shown that the number of road accidents caused by rollover both in Europe and in Turkey is increasing [1]. Therefore, rollover related accidents became the new target of the studies in the field of vehicle dynamics research aiming for both active and passive safety systems. This paper presents a method for optimizing the rear suspension geometry using design of experiment and multibody simulation in order to reduce the risk of rollover. One of the major differences of this study from previous work is that it includes statistical Taguchi method in order to increase the safety margin. Other difference of this study from literature is that it includes all design tools such as model validation, optimization and full vehicle handling and ride comfort tests. Rollover angle of the vehicle was selected as the cost function in the optimization algorithm that also contains roll stiffness and height of the roll center.

This seminar will present an introduction to Vehicle Dynamics from a vehicle system perspective. The theory and applications are associated with the interaction and performance balance between the powertrain, brakes, steering, suspensions and wheel and tire vehicle subsystems. The role that vehicle dynamics can and should play in effective automotive chassis development and the information and technology flow from vehicle system to subsystem to piece-part is integrated into the presentation. Governing equations of motion are developed and solved for both steady and transient conditions.

The rapid innovation underway with automated vehicle safety systems requires extensive evaluation and testing by system developers and regulatory agencies. The ability to evaluate heavy truck braking systems, complex, is made much more rapid, efficient, and economical through simulation employing the actual electronics and vehicle hardware. A hardware-in-the-loop pneumatic braking system was developed for this purpose by the National Highway Traffic Safety Administration. This paper describes the system in detail and includes some sample results of the testing.

The driving range of the pure electric vehicles (PEVs) greatly restricts the development of PEVs. The vehicles waste a lot of energy on account of automobiles frequently braking under the city cycle.The regenerative braking system can convert the braking kinetic energy into the electrical energy and then returns to the battery, so the energy regeneration could prolong the driving range of the PEVs. To be for high-efficient braking energy recovery, regenerative braking force and friction braking force must be reasonably distributed, in the meantime, we must take the assignment of the front axle and rear axle’s braking force for the braking safety and stability of vehicles. This paper proposes a four-wheel-drive PEV model with an electric-hydraulic brake system, on the basis of which is an additional regenerative braking system.

One important part of the vehicle design process is suspension design and tuning. This is typically performed by experienced expert evaluators with assistance from vehicle dynamics computer simulation tools. One part of this process is the development and tuning of the damping characteristics of the shock absorbers. Recently, in a series of three ASME papers published by employees of an Arkansas litigation firm, a new and supposedly “novel” approach to shock absorber damping tuning was presented. The papers propose a theory which supposedly provided an automotive engineer with a method by which rear suspension shock absorber damping could be easily selected to provide appropriate damping to the vehicle. The work is based on experiments where rubber blocks are glued to tires so as to force the rear suspension to hop and tramp.

In the context of the global energy crisis and environmental degradation, electric vehicles (EVs) have been gaining a lot of focus and attention as they run clean and are environment friendly. The electric vehicle with in-wheel motors is a promising form of EV, which is driven by four in-wheel motors. Under this mode, the driving and brake torques of each of wheel can be controlled independently. Stability control of the vehicle requires the vehicle to travel along an ideal trajectory and remain the ideal state all the time. Direct yaw moment control (DYC) has a high ability to maintain the vehicle stability in critical situation. For four-wheel independently driven (4WD) electric vehicle with in-wheel motors (IWMs), direct DYC system can work more flexibly and efficiently than internal combustion engine vehicles, because the driving/braking torque of each wheel can be controlled accurately. In this paper, a hierarchical direct yaw moment controller is developed.
