Problems solved by technology

[0003] There are many design parameters of transfer case gears, and there are many objective functions that need to be optimized. In the optimization design of gears, if every possible value of each design parameter is calculated and then the optimal solution is selected, then the calculation The steps will be very complicated, and the result cannot guarantee the global optimality, so finding a fast convergence and global optimal optimization algorithm is of great significance for improving the optimal design of transfer case gears

Abstract

The invention relates to an optimal design method of a transfer case gear, in particular to an optimal design method of a transfer case gear based on an improved particle swarm algorithm, and the method is suitable for a transfer case of a tandem type hybrid power tractor. Firstly, the volumes of all gears of the transfer case and the total center distance of the transfer case are calculated and serve as a target function, constraint conditions of related variables are determined, and then the globally optimal design parameters of the gears of the transfer case are rapidly found out through animproved particle swarm algorithm. And the method has important significance for improving the overall structure of the transfer case.

Description

technical field [0001] The invention relates to an optimal design method for a transfer case gear, in particular to an optimized design method for a transfer case gear based on an improved particle swarm algorithm, which is suitable for a serial hybrid tractor transfer case. Background technique [0002] The input and output ends of the transfer case of the serial hybrid tractor are respectively connected with the output end of the engine and the input end of the supporting rotary tiller, which is a key part of the connection of the hybrid electric tractor to the supporting agricultural implements. The structural performance of the transfer case directly affects the overall performance of the hybrid tractor and the operation performance of the supporting rotary tiller. Therefore, finding the optimal design parameters of transfer case gears for series hybrid tractors plays an important role in improving the transfer case performance. [0003] There are many design parameters...
