Abstract

The invention discloses a vehicle braking noise simulation analysis method and device, a storage medium and terminal equipment, and the method comprises the steps: obtaining the displacement of a brake pad of a vehicle at at least two preset positions on a brake disc according to a preset displacement model when the brake pad is subjected to preset braking force; according to the displacement of the brake pad at the at least two preset positions, the displacement fluctuation quantity of the brake pad is obtained, and the displacement fluctuation quantity is used for representing the braking noise of the vehicle; comparing the displacement fluctuation quantity with a preset fluctuation reference value; and when the displacement fluctuation quantity is not smaller than the fluctuation reference value, optimizing the displacement fluctuation quantity. By the adoption of the technical scheme, a complex whole vehicle model does not need to be built, simulation analysis can be conducted on the vibration source of the brake noise, simulation analysis of the brake noise can be simply and rapidly achieved, and precision and effectiveness are guaranteed.

Description

technical field [0001] The present invention relates to the technical field of vehicle braking, in particular to a vehicle braking noise simulation analysis method, device, computer-readable storage medium and terminal equipment. Background technique [0002] When the design of the brake disc and brake pads of the car is unreasonable, heavy stepping on the brake will easily cause "whining" noise in the car, which will affect the driving experience of the drivers and passengers. Usually, experience or a large number of DOE (design of experiment) can be used to analyze and optimize noise problems. However, this method takes a long time, has low efficiency and high cost. [0003] If the noise problem can be effectively predicted through simulation, the optimization efficiency will be greatly improved. However, the existing vehicle-level noise simulation analysis schemes often only analyze the noise transmission path, lack the simulation analysis of the vibration source that ge...
