摘　　要：通过C++程序以及ANSYS提供的应用编程接口,给出了一种提取ANSYSRST结果文件中节点力数据的方法。使用ANSYS对某地铁车辆焊接构架的有限元模型进行静力学求解,获得包含节点力数据的RST文件,并将该方法读取的节点力数据与疲劳寿命计算软件WeldFatigue的计算结果进行对比,验证了利用该方法提取数据的准确性与适用性。A method for extracting the node force data in the ANSYS RST result file is presented by using the C++ program and the application programming interface provided by ANSYS.ANSYS is used to solve the finite element model of a subway vehicle's welding frame,and the RST file containing the node force data is obtained.Finally,the accuracy and applicability of the method is verified by comparing the node force data with the calculation results of the fatigue life calculation software Weld Fatigue.
