Abstract

The invention provides a gear transmission system design method based on particle swarm two-level optimization. The method comprises the following steps that an optimal objective function is set, an optimal variable to be optimized is set, an optimal constraint is set, and an optimal solution gbest of the optimal variable is acquired through the particle swarm two-level optimization. According to the method, the optimal variable of a gear transmission system is acquired by the adoption of the particle swarm two-level optimization, the first level optimization is focused on meeting the requirement that the standard deviation of safety coefficients of contact fatigue strength of all external gears is small, and acquiring a feasible scheme of the number of gear teeth; and the second level optimization is focused on meeting the requirement that the standard deviation of safety coefficients of bending fatigue strength of all the external gears is small, and acquiring a refinement configuration scheme including all design variables. All strength indexes of the optimal gear transmission system are met, meanwhile, the difference of service lives of all the external gears is relatively small, the problem that short board effect often occurs in the gear transmission system can be avoided effectively, and reliability of the gear transmission system is improved.

Description

technical field [0001] The invention relates to a design method of a gear transmission system based on particle swarm two-layer optimization, in particular to a design method of a megawatt-level wind power generator planetary transmission gearbox based on particle swarm optimization technology. Background technique [0002] The main gearbox of the wind turbine is a very important mechanical component in the unit, and the transmission system inside it has a large transmission ratio and high transmission power. Wind power gearboxes are often installed in remote wilderness, high mountains, sea areas, etc., where they are difficult to reach; the cabin space where the gearbox is located is very small, and maintenance is very difficult, and if the gearbox is hoisted from the wind turbine to the ground for maintenance, the cost is unbearable; this It forces the fan gearbox to have higher reliability requirements than ordinary gearboxes. About 90% of the damage of the wind turbine ...
