Abstract

The invention discloses a vehicle suspension system parameter optimization method based on an adaptive behavior game algorithm. The method comprises the following steps: establishing a game model; taking the smoothness comprehensive evaluation index and the operation stability evaluation index as two players in the game model; selecting damping and rigidity as optimization design variables, processing the variables by using a clustering algorithm, converting a function constraint condition into a strategy space constraint condition which can be selected by each player, and obtaining a strategy set of each player; and establishing an adaptive behavior rule, determining a revenue function expression of each gaming party, establishing an adaptive behavior game control model, and setting a game convergence criterion. The operation stability and the smoothness are taken as game participants to be considered at the same time by adopting a game algorithm with relatively high conflict solving capability, a game player strategy set and constraints thereof are established, and an optimal value is obtained according to a convergence criterion and is taken as a suspension system parameter meeting a required solution.

Description

technical field [0001] The invention relates to the technical field of automobile chassis, in particular to a parameter optimization method of a vehicle suspension system based on an adaptive behavioral game algorithm. Background technique [0002] Suspension is one of the important assemblies of modern automobiles. Its main task is to transmit all the forces and moments acting between the wheels and the frame, to ease the impact of the road surface, to ensure that the vehicle can run normally when the road surface is uneven, and to ensure that the load changes. Cars gain the ability to travel at high speeds. In fact, in the parameter matching design of the suspension system of the automobile, on the one hand, all suspension components need to be installed in the limited suspension space; on the other hand, the suspension is related to various performances of the automobile. For these properties, the suspension system must ensure that the car has good ride comfort and handl...
