Front Crash

Traffic accidents cause to a large quantity of personnel casualty and economic loss every year. The safety in vehicle crash has been one of important criterions in vehicle design. In this study a three-dimensional finite element model was established and the front crash process of car bodywork was analyzed. The simulation results show that the structure design of car bodywork is reasonable and of safety for the passengers. The investigation of this study not only validates the rationality of the car bodywork design but also provides a detailed numerical simulation model for further investigation as well as improvement and optimization of the car bodywork structure.

Abstract The effects of variations in stiffness and geometry on the nonuniformity of tires are investigated by using the finite element analysis. In order to evaluate tire uniformity, a three-dimensional finite element model of the tire with imperfections is developed. This paper considers how imperfections, such as variations in stiffness or geometry and run-out, contribute to detrimental effects on tire nonuniformity. It is found that the radial force variation of a tire with imperfections depends strongly on the geometrical variations of the tire.

A short explanation of the finite element method as a powerful tool for mathematical modeling is provided, and an application using constitutive modeling of the behavior of ligaments is introduced. Few possible explanations of the role of water in ligament function are extracted from two dimensional finite element models of a classical ligament. The modeling is extended to a three dimensional finite element model for the human anterior cruciate ligament. Simulation of ligament force in pitching motion of basketball player is studied in this paper.
