| 摘 要： | 用Fourier级数方法推导了无约束自由杆承受运动刚体纵向冲击作用下的响应,将刚性位移直接由总位移中分离出来,并分析了无约束自由杆的刚性位移与弹性位移的关系及其影响因素。数值算例表明只要选取足够多级数项进行叠加,可以得到精确的结果。

| Abstract: | The Fourier-series method is adopted to analyze the responses of an unrestrained bar under a rigid axial impact.The rigid response of the bar is separated directly from its total response of the bar and the relationship and affecting factors between the rigid displacement and elastic displacement of the bar is investigated.The numerical evaluations show that if enough terms of the series are chosen,the accurate solution is expectively obtained. |
