Abstract

The invention belongs to the technical field of shaft head dynamic load testing, and discloses a shaft head dynamic load calculation method and device, equipment and a storage medium. The method includes the steps of during test of a car to be tested under a preset road condition, acquiring working condition data corresponding to a sensor at a preset position on the car to be tested in real time;acquiring a transfer function corresponding to the sensor; and according to the working condition data and the transfer function, calculating a dynamic load of a shaft head by means of a preset inverse matrix formula. In the above manner, when the dynamic load of the shaft head is measured, the time period is reduced, so that the cost is reduced and the efficiency is improved.

Description

technical field [0001] The invention relates to the technical field of shaft head dynamic load testing, in particular to a shaft head dynamic load calculation method, device, equipment and storage medium. Background technique [0002] Vehicle noise, vibration and harshness (Noise, Vibration, Harshness NVH) performance is one of the key indicators to measure the performance of the vehicle. Vibration and noise caused by road conditions are important input sources of vehicle NVH. In the NVH simulation system, currently the most advanced road surface excitation vehicle interior vibration and noise analysis in the world usually has two methods, one is to use the tire displacement excitation generated by the road spectrum, that is, to load the displacement spectrum into the model by collecting the road surface displacement spectrum. The ground contact point of the dynamic tire is used to obtain the noise inside the vehicle; the other is to collect the dynamic load of the axle head...
