利用模态叠加法计算得到安装非线性能量阱前后欧拉梁的振动响应(vibration responses of the euler beam with a nonlinear energy sink is solved by using modal method)

基于精细积分方法构造的HIPSM和HPESM，算例用于求解欧拉梁振动响应求解(Based on the precise integration method, hipm and hpesm are constructed, and a numerical example is used to solve the vibration response of Euler beam)
