Abstract
With the development of computing technology in recent years, numerical simulation system is developed to calculate the body behavior on a computer. There are some advantages of applying numerical simulation in vehicle development. For example, the cost reduction, safety and easiness of changing parameters. Furthermore, development of small-sized vehicle has been investigated. As the mass of vehicle comes close to that of occupant, coupling behavior between them is increasing. Therefore, it is very important to consider dynamic property of the human body in the vehicle development. In this research, we simulate the dynamics of the human body riding on a vehicle, and we construct a system for generating the body motion. The model is optimized by applying genetic algorithm to the parameter. Moreover we modified parameter to consider the effect of analysis result.
