本文涉及由球和平面组成的冲击系统的建模和分析。提出了考虑影响持续时间和能量消耗的影响模型。通过在赫兹接触理论中引入复刚度系数来公式化由于冲击而产生的合力。根据合力的表达式，冲击系统由非线性弹簧和非线性缓冲器建模。非线性弹簧的特性用赫兹理论来表达，非线性缓冲器的特性用位移和速度的函数来表达。模型参数由冲击系统的配置、材料值和恢复系数决定。实验和仿真验证了所提模型的准确性，并且表现出良好的一致性。
This paper deals with modeling and analysis of an impact system, which is composed of ball and plane. An impact model considering both duration of impact and energy ioss is proposed. The Resultant force due to impact is formulated by introducing a complex stiffness coefficient in Hertz's contact theory. From the expression for the resultant force, the impact system is modeled by both a nonlinear spring and a nonlinear dashpot. The characteristics of the nonlinear spring is expressed by using Hertz's theory, and that of the nonlinear dashpot is expressed by a function of the displacement and the velocity. The model parameters are determined by the configuration, the material value and the coefficient of restitution in the impact system. Experiment and simulation are carried out to demonstrate the accuracy of the proposed model, and good agreement is shown.
