The purpose of computer modeling of a vehicle system is to develop basic methods for computer formulation and solution of the equations of motion. This requires systematic techniques for formulating the equations and numerical methods for solving them. The computer program developed here for the analysis of vehicle system dynamics is a special purpose program. It deals with only a specific type of application say lateral stability or dynamic response. The equations of motion for that particular application are derived a priori and then formulated into the program. As input to the program, the various data's like, mass of the entire vehicle, sprung mass, unstrung mass etc., the initial values of parameters of a vehicle system have been provided. Such a special purpose program can be made computationally efficient and its storage requirement can be minimized with the result that it will be suitable for implementation on small personal computers.Keywords

The car suspension system of this model contains two parts. The first part deals with the formulation of a mathematical model for a conventional full car passive suspension system. Typically, the mathematical modeling is done on the basis of mechanical network analysis. The second part deals with simulation of the mathematical model of the suspension system. Simulation is carried out using MATLAB. Program was carried out for MATLAB and the simulation results were obtained in the form of graphical plots.Keywords

The thermal properties of doped Azopolyester were obtained by solution casting technique. Many theories have been suggested by various thermal stability mechanisms in organic solids. Since the polymers of the present study behave like semiconductors, these theories may be extended to explain thermal stability. In this section, the thermal stability theories proposed by O'Dwyer, TGA analysis, and measurements were discussed. The thermal stability properties reveal that the conductivity is appreciable in the temperature ranging from 30°C to 70°C (303 to 343K) and when it is more than 70°C (343 K) the conductivity is drastically reduced and polymeric blends undergo a gradual weight loss in the temperature ranging from 400-800°C due to attributed loss of volatile solvents trapped in the polymer. These studies are done with the help of O'Dwyer basic theory of thermal stability.Keywords
