Abstract

The invention belongs to the technical field of vehicle evaluation, and discloses a durability analysis method and device based on torque influence, equipment and a storage medium. The method comprises the following steps: extracting a hard point virtual load signal from a virtual test field simulation result; obtaining a torque virtual load spectrum and a torque-free virtual load spectrum according to the virtual test field simulation result and the hard point virtual load signal; establishing a finite element model of the target vehicle, and determining a test hard point according to the finite element model; carrying out a unit force loading test on the test hard point to obtain a test result; performing fatigue durability analysis on the target vehicle according to the test result, the torque virtual load spectrum and the torque-free virtual load spectrum to obtain a reference durability analysis result; and performing damage value evaluation test according to the durability analysis result to obtain a target durability analysis result. Under the condition of no physical sample vehicle and no actual road surface collection road spectrum, the influence of the torque on the whole vehicle fatigue durability simulation analysis result is evaluated, the vehicle development period is shortened, and the cost is saved.

Description

technical field [0001] The present invention relates to the technical field of vehicle evaluation, and in particular, to a method, device, device and storage medium for durability analysis based on torque influence. Background technique [0002] At present, due to the advantages of low cost and short development cycle of virtual test field, the simulation technology of virtual test field has been widely used. Because the influencing factors of torque are uncontrollable, it is difficult to adjust the dynamic model to make the torque benchmarking well, so the accuracy of the wheel center torque TX / TY / TZ has never been included in the load benchmarking category. In the case of uncontrollable torque accuracy, the impact evaluation of torque on the results of fatigue and durability simulation is not accurate, resulting in low reliability of fatigue and durability simulation. [0003] The above content is only used to assist the understanding of the technical solutions of the pre...
