摘要
移动荷载作用下,基于欧拉-伯努利梁理论对功能梯度梁的力学响应进行了研究。借助性能优越的弱式求积单元法进行数值计算,并将结果和现有文献进行了对比。研究表明:弱式求积单元法可以快速便捷地计算功能梯度材料梁。此外,边界条件以及移动荷载速度对梁的动态响应有比较大的影响。一定条件下,可以借助各项同性材料梁的结果计算功能梯度材料梁的动态响应,这对工程实践具有积极意义。
Based on Euler Bernoulli beam theory, the mechanical response of functionally graded beams under a moving load is studied. The numerical calculation is carried out with the help of the weak form quadrature element method which is of superior performance, and the results are compared with the existing literature. The results show that the weak form quadrature element method can calculate functionally graded material beams quickly and conveniently. In addition, the boundary conditions and moving load speed have a great influence on the dynamic response of the beam. Under certain conditions, the dynamic response of functionally graded material beams can be calculated with the help of the results of isotropic material beams, which is of positive significance to engineering practice.
