摘要
文章利用HyperMesh软件建立了B型地铁铝合金车体有限元模型,并利用ANSYS软件对车体结构进行了模态计算,得到了4种方案下车体的前六阶固有频率及相应振型。根据计算结果提出了改进车体结构的建议。
A detailed finite element modal of aluminum alloy car body for type B metro vehicle is established using the software HyperMesh. The inherent frequencies and modal shape of the first 6 order modes are found respectively through modal calculation under 4 kinds of case using software ANSYS. Suggestions on improvement of the car body structure are given on the basis of the calculation results.
