摘要
首先设定了较为准确的形函数,然后利用大型数学软件Mapple采取伽辽金法对悬臂外伸梁在不同荷载作用于形心的临界荷载进行了推导,并运用ANSYS对不同整体稳定模型进行了模拟分析,验证了理论公式的正确性及适用条件.
The first article sets a more accurate shape function,and then it takes advantage of large-scale mathematical software Mapple for derivation on the centroid of the critical load at different loads for cantilever outrigger beam in Galerkin method and use of ANSYS for the overall stability of the model to simulate different analysis to verify the correctness of the theoretical formula and applicable conditions.
