Rocking Block线碰撞离散化研究

RESEARCH ON DISCRETIZATION OF LINE IMPACT IN ROCKING BLOCK

针对Rocking Block中的线碰撞问题,首先采用离散化思想将线碰撞问题离散为多点碰撞系统,而后基于LZB方法对所建多点碰撞系统进行动力学建模.仿真结果表明随着离散点数的增加,基于LZB方法的多点碰撞模型能够很好地刻画Rocking Block中的相关线碰撞问题,且精度与离散程度紧密相关.

Modeling the dynamics of line impact with the friction in Rocking Block has attracted the attention of scientists for a long time. Firstly,this paper converts the line impact to multi-point impact using discretization principle. Secondly,the multi-point dynamic model is then constructed based on the LZB method. Simulation results show that the LZB method and discretization principle are effective in modeling line impact,and the precision are improved with the increasing number of discrete points.
