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.

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.

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.

This workbook, a companion to the book Road Vehicle Dynamics, 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. Emphasizing application more than theory, the workbook 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.
