摘要
为优化电枢结构参数设计,利用有限元分析软件ANSYS进行电枢与轨道二维模型过盈装配仿真计算,并采用L16(45)的正交试验法,以电枢与轨道间的总接触压力为考察指标,通过分析得到电枢结构参数对枢轨接触压力的影响规律。针对不同幅值的脉冲电流,通过“1g/1A法则”确定枢轨间所需要的接触压力,并选取结构参数最优的电枢为例,说明电枢与轨道间的接触特性。
In order to analyze and optimize the structural parameter design of the armature, the finite element analysis software ANSYS was used to simulate the interference assembly of the armature and the orbital three-dimensional model, and the orthogonal test method of L 16 (4 5) was adopted to take the total contact pressure between the pivots. The index was investigated and the influence law of the armature structure parameters on the contact pressure of the pivot rail was obtained through analysis. For the pulse currents of different amplitudes, the required contact pressure between the pivot rails was determined by “1 g/1 A rule”, and the armature with the best structural parameters was selected as an example to illustrate the contact characteristics between the armature and the track.
