摘要
对自由梁在两端受非对称阶跃载荷作用下的动力响应进行了理论分析,得到了不同载荷量级下的变形模式,并指出所得结果为下一步冲击载荷作用下自由梁的瞬态动力响应研究奠定了基础。
The dynamic response of a free beam with uniform rectangular cross-section subjected to step-loading at both free-end is analyzed theoretically in this paper, and the deformation modes for different magnitude loadings are obtained. The results can be employed as a basic work for studying the instantaneous dynamic response of a free beam subjected to complicated impulsive loading.
