Mathematical modeling of any system plays an important role in research and engineering applications. Development of hydropneumatic suspension system requires a complete understanding of physical phenomenon and generating governing equations of the same. In this paper, mathematical model of a typical hydropneumatic suspension system is made and simulation of such a complex multi domain system is programmed in MATLAB Simulink software. Vibration isolation potential of hydropneumatic suspension system is investigated through mathematical modeling, incorporating nonlinearity due to polytropic nature of gas spring.

Braking system is one of the most important system in the vehicle. In this paper, a general methodology for the design of braking system for a light military tracked vehicle is discussed in detail. It may be considered as a guide for predicting the values of various braking terms (such as brake force, brake torque, system pressure required, pedal force etc.) for the given inputs. The effects on these braking terms due to the variation of the inputs are also analyzed. A complete study of different types of brake actuation system has been done so that the appropriate one can be selected. A methology has been derived for braking system design for tracked vehicle and a program is written for the same.

In this paper hydropneumatic suspension system design methodology for light military tracked vehicle is discussed in detail. A guide to locate the major impact factor & its effect on the system level design is demonstrated. Spring & damping characteristics of hydropneumatic suspension have significant bearing on the tracked vehicle mobility characteristics. A methodology has been derived to optimize the kinematics of the suspension system by optimizing the load transferring leverage ratio resulting in enhanced system life. The paper also discusses the analytical method used for prediction of spring & damping characteristics and the factors affecting them.
