This set combines the book Road Vehicle Dynamics with its corresponding workbook companion, Road Vehicle Dynamics: Problems and Solutions. Road Vehicle Dynamics provides a detailed overview of the dynamics of road vehicle systems, giving readers an understanding of how physical laws, human factor considerations, and design choices affect ride, handling, braking, acceleration, and vehicle safety. Chapters cover analysis of dynamic systems, tire dynamics, ride dynamics, vehicle rollover analysis, handling dynamics, braking, acceleration, total vehicle dynamics, and accident reconstruction. The workbook will enable students and professionals from a variety of disciplines to engage in problem-solving exercises based on the material covered in each chapter of that book. It presents systematic rules of analysis that students can follow in a step-by-step manner to understand the efficiencies or shortcomings of various techniques.

Readers will gain a greater understanding of the factors influencing ride, handling, braking, acceleration, and vehicle safety.

This paper studies the dynamics and noise of timing belt. A comprehensive theoretical contact dynamics model for belt tooth-sprocket tooth pair is developed. The general belt dynamics model in conjunction with the contact model is used to quantify the impact-sliding process of belt tooth. The effect of tooth meshing process is illustrated which results in the vibrations of belt span and tooth vibrations. The structural borne noise consists of structural impact portion and friction-induced portion. The relationship between system parameters and noise is quantified. The air borne noise due to air-pumping is investigated based on Lighthill's equation. A comprehensive model is developed and the spectrum signatures of the air-pumping noise are illustrated.

Serpentine belt system has been widely used to drive automotive accessories like power steering pump, alternator, and A/C compressor from a crankshaft pulley. Overload under severe conditions can lead to excessive slippage in the belt pulley interface in poorly designed accessory systems. This can lead to undesirable noise that increases warranty cost substantially. The mechanisms and data of these tribology performance, noise features and system response are of utmost interest to the accessory drive designers. As accessories belt systems are usually used in ambient condition, the presence of water on belt is unavoidable under the raining weather conditions. The presence of water in interface induces larger slippage as the water film in interface changes the friction mechanisms in rubber belt-pulley interface from coulomb friction to friction with mixed lubrication that has negative slope of coefficient of friction (cof) - velocity.

One of the major applications of cam mechanism is valve actuation of Internal Combustion (IC) engines. This work deals with the follower response determination for a given prescribed cam motion for single DOF cam mechanism. Here follower response by two methods are presented first one is using Johnson's numerical method analytically obtained the dynamic response. In the second method transient dynamic analysis is carried out using FEM. Here each method is carried out considering two types of cam motions, parabolic motion and cycloidal motion. The responses of both methods are yielding good agreement.

This paper describes an optimization methodology for damage detection in an automobile driveline system. When a constant nature of excitation such as harmonic or pulse is transmitted from the engines, the torsional response at various points along the driveline should remain same under various trails. But in actual practice, due to the deterioration and minute cracks developed along the driveline, a slight variation from the baseline response data is often observed. In other words the changes in the response history is an indication of the changes in the system parameters. In this paper driveline system is modeled using finite element method with consideration of reductions in stiffness of each element. If there be no damage in any element, the overall response when substituted in original equation of motion should not be a non zero quantity. Otherwise, the difference termed as residue has to be accounted and minimized.

The objective of this paper is to explore the dynamic features of vibrations and instability in automotive front end accessory drive belt system. To address this issue, a non-linear model of a moving beam with friction coupling on elastic foundation is developed. The model takes into account of a variety of nonlinear effects, including the contact stiffness nonlinearity, nonlinearities associated with the friction, tensioned parametric excitation, as well as the beam geometry nonlinearity. Different nonlinear properties are examined, and numerical simulations are conducted to investigate the system and to correlate with the experimental results. The major contributors to the dynamic contact instability are illustrated and are attributed to modal coupling and/or negative damping.

This paper describes a real time application of mechatronics with constructional details along with simulation results. Applications like part tracking and automatic speed control are of interest to the industry and the academic alike. Based on certain specific information about the system a control program is prepared and embedded in a microcontroller, so that it responds repetitively to various input parameters. To widen the range of control, it is necessary that a huge database of input-output information has to be provided to the microcontroller. In this paper, different sensing and actuating elements and details of microcontrol programming are presented with reference to typical applications such as component recognition strategy using a vision system, a remote controlled mobile robot, tracking system of moving components, and automatic speed control of laboratory diesel engine model. Some simulation results of the control are also presented.

High strength combined with minimum weight is a distinctive feature of thin-walled beams of open cross-section. A high degree of material economy can be achieved by using non-uniform members of this type. This is the salient feature of thin-walled structural members of open sections such as H, Z, T channel and angle sections. Tapered thin-walled members of open sections are frequently employed for their structural efficiency. In the present analysis torsional behaviour of steel tapered cantilever beam subjected to time-invariant axial compressive load is investigated. To infer its torsional behaviour, secondary effects such as rotary inertia and effect of warping have been taken into consideration. In this work frequency analysis of thin-walled tapered I-sections is carried out to obtain the natural frequencies and corresponding mode shapes. The numerical solutions are obtained from finite element method.

A numerical integration method is developed for solving more general singular perturbation problems. Firstly, we discuss the problems with mixed boundary conditions and a left end boundary layer. Secondly, we discuss the singular-singular perturbation problems. Finally, we discuss the problems with mixed boundary conditions and a right end layer. Numerical experiments with the method for several model linear and non-linear examples with left end boundary layer or right end boundary layer are presented and compared with exact solutions.

An automatic control approach based on the method of pole-placement is presented in this paper. This method is an alternative to the conventional frequency response approach and root locus design. Unit step response of the system is initially plotted and stability is tested. The unstable system is made stable to a specified settling times and overshoots by choosing system gains using Ackerman’s formula. The stability is finally ascertained with Bode diagrams. The approach is illustrated with two numerical mechanical systems.

The paper proposes an approach based on Taguchi’s method to predict the optimum process parameters and forecasts the outputs at these parameters using neural networks. The predicted data from Taguchi’s Design of Experiments (DOE) is quite useful in obtaining optimised output parameters, using some regression models. In multiple input (MI) systems, with no cost function defined explicitly in terms of system variables, Taguchi’s solution provides best accurate alternative. Neural networks on the other hand provide the output corresponding to the optimum process parameters obtained in Taguchi method. A case study demonstrates the approach. Results are presented in the form of graphs and tables.
