Description
technical field [0001] The present application relates to the technical field of computer software, in particular to a method, device and equipment for analyzing the torsional vibration of a shaft system of a variable-speed planetary gear unit. Background technique [0002] The variable speed planetary gear unit belongs to a kind of gearbox, which is composed of planetary ring gear, sun gear, planetary gear (also known as satellite gear) and gear wheel shaft. According to the motion relationship of the ring gear, sun gear and planetary gear, the input can be realized The shaft and the output shaft are separated from the rigid transmission relationship, the input shaft and the output shaft are transmitted in the same direction or in the opposite direction, and the transmission ratio of the input and output shafts is changed, and are widely used in land, navigation, aviation and other transportation tools. [0003] However, due to the complex structure of the variable speed pl...
