摘要

摘要本文分析了均匀、各向同性粘热弹性梁在谐波荷载作用下的横向挠度。考虑梁的两端在不同的边界条件下(两个轴端夹紧,两个轴端简支,左端夹紧,右端自由)。利用拉普拉斯变换研究了挠度。利用MATLAB软件对经拉普拉斯逆变换得到的挠度解析表达式进行了数值计算。讨论了在不同时间和长度的边界条件下的图形观测结果。上述工作在谐振器设计中具有一定的应用价值。

Analysis of Deflection in Visco-Thermoelastic Beam Resonators Subjected to Harmonic Loading
Abstract This paper analyses the transverse deflection in a homogeneous, isotropic, visco-thermoelastic beam when subjected to harmonic load. The ends of the beam are considered at different boundary conditions (both axial ends clamped, both axial ends simply supported and left end clamped and right end free). The deflection has been studied by using the Laplace transform. Numerical computation of analytical expression of deflection obtained after Inverse Laplace transform has been done using MATLAB software. The graphical observations have been discussed under various boundary conditions for different values of time and length. The above work has applications in design of resonators.
