【摘要】:針對(duì)受集中力質(zhì)量在受分布力弦上移動(dòng)時(shí)的振動(dòng)響應(yīng)問題,發(fā)展了一種半解析求解方法。首先根據(jù)力學(xué)模型建立了振動(dòng)方程,然后利用傅里葉變換得到了方程的矩陣形式,并采用Newmark方法編程進(jìn)行了數(shù)值求解。同時(shí)為驗(yàn)證方法的正確性,針對(duì)特定條件下的振動(dòng)方程推導(dǎo)了解析解。最后通過半解析求解結(jié)果與解析解和文獻(xiàn)的對(duì)比分析,驗(yàn)證了該方法的正確性。
[Abstract]:A semi-analytical method is developed to solve the vibration response of a concentrated mass moving on a distributed force string. First, the vibration equation is established according to the mechanical model, then the matrix form of the equation is obtained by Fourier transform, and the numerical solution is carried out by using Newmark method. In order to verify the correctness of the method, an analytical solution is derived for the vibration equation under certain conditions. Finally, the correctness of the method is verified by comparing the semi-analytical solution with the analytical solution and literature.
