In order to avoid the transmission failure occurred during operation of the planetary carrier of the traction unit in MG400/930-WD shearer, FEA was carried out on the planetary carrier and optimization program was proposed. The working principle of the planetary carrier was elaborated and its 3D model was established. Statics analysis, modal analysis and harmonic response analysis on the planetary carrier were carried out based on ANSYS Workbench, and the displacement contours, stress contours, nature frequency and frequency response of the planetary carrier were obtained. Analysis results showed that the optimized planetary carrier satisfied the working demand. The study results provided a theoretical basis for the design of MG400/930-WD shearer.
