【摘要】 随着科学技术的发展,分析力学在碰撞问题中的应用日趋重要,本文推导了撞击运动的拉格朗日方程,并举例说明了其应用,分析了铰接四刚杆结构撞击运动的实例。给出了撞击后速度与夹角的关系曲线,及撞击冲量和动能损失与恢复因数、夹角的关系曲线。更多还原

【Abstract】 Along with the science and technology development,the application of analysis me- chanics is important in the collision question day by day.In this article,Lagrange equation about the impact movement is inferred,explained its application with examples,the example of four joint- ed link impacting movement is analyzed.It has given the relation curve between the speed and the included angle,and relational curve between the hit impulse,the kinetic energy rejection and re- store the factor,the included angle after the impact.更多还原
