The invention discloses a timing belt transmission system noise test method, equipment, a storage medium and a device, and the method comprises the steps: determining a plurality of noise collection points according to a timing belt transmission system model when a noise test instruction is received, and carrying out the vibration simulation test according to the timing belt transmission system model under a preset idling condition, obtaining a transverse vibration amplitude of each noise acquisition point, and generating a noise test result of the timing belt transmission system model according to the transverse vibration amplitude; compared with an existing mode that the goose noise of the timing belt transmission system is determined by manufacturing different timing belt transmission system samples for testing, due to the fact that the noise level of the timing belt transmission system model can be rapidly determined in the initial stage of project design, a goose noise test can be carried out without manufacturing a timing belt transmission system sample piece, the development period of the timing belt transmission system is shortened, and the development cost of the timing belt transmission system is reduced.
Description
technical field [0001] The invention relates to the technical field of automobiles, in particular to a noise testing method, equipment, storage medium and device of a timing belt transmission system. Background technique [0002] As people's requirements for vehicle comfort are getting higher and higher, the performance requirements for engine noise, vibration and harshness (Noise, Vibration, Harshness, NVH) are also becoming more and more stringent. The timing transmission system is an important part of the engine, therefore, the performance of the timing transmission system directly affects the NVH performance of the engine. [0003] Because the timing belt transmission system has lower friction loss and less noise performance, the timing belt transmission system is often used as the timing transmission system of the vehicle in the prior art. However, when the timing belt drive system is parked or the engine is idling, the goose noise of the timing belt is relatively larg...
