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.

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.

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.

In two wheelers the front suspension system is mounted on chassis by two steering bearings which are lubricated ball type angular contact bearings with significant radial force components. These bearings are designed to withstand maximum vehicle loads for target durability. Maximum load carrying capacity depends on the number and size of the balls, bearing size and material. For target durability with designed load carrying capacity, the ball contact pressure, bearing preload plays a major role as compared to other design parameters. Geometry parameters and maximum load defines contact pressure for given bearing design. But in two wheelers due to nature of usage and road conditions, the peak loads are dynamic and geometry based design calculations may not yield the most optimal bearing design. In this work the bearing ball race profile design is optimized by using dynamic bearing contact profiles by using nonlinear Finite Element Analysis.

Owing to the recent developments in sensors with reduced size and weight, it is now possible to install sensors on a body of a motorcycle to monitor its behavior during running. The analysis of maneuverability and stability has been performed based on the data resulted from measurements by these sensors. The tire forces and moments is an important measurement item in maneuverability and stability studies. However, the tire forces and moments is difficult to measure directly, therefore, it is a common practice to measure the force and the moment acting on the center of the wheel. The measuring device is called a wheel forces and moments sensor, and it is widely used for cars. The development of a wheel forces and moments sensor for motorcycles has difficulty particular to motorcycles. First, motorcycles run with their bodies largely banked, which restricts positioning the sensors.

Tires influence the dynamic performance of the motorcycle and the development of tires to meet these requirements has always been one of the critical and challenging tasks for the motorcycle industry. The tire characteristics and rest of the motorcycle design need to be tuned extensively to achieve the desired performance and this work requires estimating tire force characteristics upfront. The aim of this study is to develop feasible test methods to measure the lateral force characteristics of motorcycle tires. This work is an extension of our previous work on estimating the longitudinal forces of motorcycle tires. In this work, new experimental procedures are developed to estimate the friction ellipse and lateral stiffness characteristics of motorcycle tires. A fairly accurate tire model is developed using the measured lateral force characteristics.

In recent years three-wheel camber vehicles, with two wheels in the front and a single rear wheel, have been growing in popularity due to their excellent stability and motorcycle-like handling. We call this kind of vehicle a “Leaning Multi Wheel category” vehicle (hereinafter referred to as a “LMW vehicle”) and have been pursuing research and development of these vehicles. A LMW vehicle has various characteristics, but one of them stands out in particular. When a LMW vehicle is cornering, if one of the front wheels passes over a section of road surface with a low friction coefficient, there is very little disturbance to the vehicle’s behavior, it remains stable, and can continue to be driven as normal. However, there has been no investigation into why these vehicles have this particular characteristic and so there is a need to clarify this phenomenon theoretically from the standpoint of understanding these vehicles better.

Increased public pressure to improve commercial truck safety and new stopping distance regulations have intensified the need to better understand the factors influencing heavy vehicle braking performance. To assist individuals and their organizations in preparing for these new truck braking standards, this seminar focuses attendees on understanding medium-duty hydraulic brake systems and heavy-duty air brake systems and how both systems' performance can be predicted, maintained and optimized.

Hydraulic brake systems, one of the most important safety features on many road vehicles today, must meet manufacturer and customer requirements in addition to Federal Motor Vehicle Safety Standards. This course will analyze automotive braking from a system's perspective, emphasizing legal requirements as well as performance expectations such as pedal feel, stopping distance, fade and thermal management. Calculations necessary to predict brake balance and key system sizing variables that contribute to performance will be discussed.

The design of a car or truck always involves a conflict of goals. The suspension system that is optimized for ride is not always the best for handling. The powertrain that gives best acceleration is not likely to be the most fuel-efficient. Through this course, you will develop an understanding of the motor vehicle as a system.
