Abstract
In the finite element calculation of three-dimensional impact mechanics, there are usually such problems as large memory consumption and more machine consumption, which leads to a great waste of power resources. Based on the analysis of the calculation process of three-dimensional penetration sliding surface, a method of improving the calculation efficiency is proposed, which is the cell search method, based on the comparison calculation and without affecting the calculation accuracy. This method only judges the main elements in the cell involved by the slave nodes in the penetration channel area, greatly reduces the calculation amount of the elements, and improves the efficiency of the program calculation. The method is applied to the programming of finite element, and the results are satisfactory. The application of cell search method has played a good role in promoting the development of energy-saving technology.
