我国森铁转向架摇枕的强度计算,一直沿用传统的古典力学计算方法.即简化为不等截面的简支梁进行计算.这种计算方法简单,但不能反映开孔边缘应力集中和截面的应力分布规律,计算结果误差大.采用有限元法运用电子计算机进行结构强度计算,可以模拟真实的载荷情况,
The strength calculation of the bolster of Moritake bogie in China has been using the traditional classical mechanics calculation method, that is, the calculation of simple girders simplified to unequal sections is simple, but it can not reflect the stress concentration and cross section Stress distribution, the calculation error is large.Using the finite element method to calculate the structural strength by the electronic computer, you can simulate the real load situation,
