摘    要:把处于碰撞状态下之碰撞体与靶体看作是一个振动体系,于是可把弹性碰撞问题转化成该体系在部分体系(碰撞体)具有初始扰动速度下的振动响应问题而纳入常规的振动分析范畴.典型示例表明用这种对策可以方便地得到与波动解完全相同的结果.

关 键 词:碰撞  振动  波传播  接触  模态

Abstract:The impactor and target are considered an integrated system of vibration, so the elastic impact problem can be dealt with as a problem of conventiollal dynamic response analysis of the system under the initial condition that a and only a part of the integrated system (impactor) is subjected to a given velocity distribution. The results of clajssical illustrative examples obtained by the suggested strategy agree with those obtained by the wave theory very well and uniform convergence can be achieved if more and more modes are included.
Keywords:impact  vibration  wave propagation  contact  mode
