Control method and system for simulating part performance test

Abstract

The invention discloses a control method for simulating a part performance test, relates to the field of engine part performance tests, and solves the technical problem of low efficiency of an existing part test mode. The method comprises the steps: monitoring the resonance inertia force of a vibration device provided with a part in real time, obtaining the amplitude of the resonance inertia forceaccording to the time curve of the resonance inertia force, and enabling the vibration device to work in a resonance state consistent with the inherent frequency of a control system according to theamplitude of the resonance inertia force. The amplitude of the resonance inertia force of the vibration device in the resonance state is used for representing the magnitude of the dynamic load borne by the part. The invention further discloses a control system for simulating the part performance test. According to the invention, the vibration of the part can always work on the resonance point through a closed-loop control system, the waveform distortion degree is small, the work is stable, the test result is accurate, and the work efficiency is effectively improved.

Description

technical field [0001] The present invention relates to performance testing of engine parts, more specifically, it relates to a control method and system for simulating performance testing of parts. Background technique [0002] When the car is running, the whole car will be affected by vibration due to the road surface. Especially when the car is running on non-paved roads, mountain roads and other relatively uneven roads, the parts in the engine will be subject to greater vibration. If the parts themselves have defects, this will cause parts to deform, break, and bend. In addition, if the engine works in different environments such as plateau, heat, hypoxia, and low temperature, the parts of the engine will be more fragile and more prone to deformation, fracture, and bending. Therefore, the parts of the engine need to undergo performance tests before leaving the factory, mainly including dynamic load performance tests and static load performance tests. At present, the lo...
