Problems solved by technology

[0004]However, there are 8-16 hard points that need to be loaded in a structural part of the vehicle, and the strength and durability assessment work that needs to be carried out on each hard point There are also 20-50 cases. Further, loads need to be applied in 6 directions on each hard point, and then thousands of times of load application are required to complete one load loading for a structural member. The manual operation process is cumbersome and consumes It takes a long time and is prone to errors, which reduces the efficiency of simulation work. At the same time, it is difficult to find errors, which seriously affects the design of subsequent vehicle performance.

Abstract

The embodiment of the invention discloses a load loading method and device, equipment and a storage medium. The method comprises the steps of obtaining a to-be-loaded structural member of a vehicle and a whole vehicle model corresponding to the vehicle; determining a hard point loading template corresponding to the to-be-loaded structural member, and determining a hard point load result of each hard point in the vehicle according to the whole vehicle model; and matching and replacing the hard point loading template according to the load result of each hard point, and determining the matched and replaced hard point loading template as a load loading file of the to-be-loaded structural member. According to the technical scheme, when structural strength durability simulation is carried out on the to-be-loaded structural component in the vehicle, load loading can be directly and automatically carried out on the to-be-loaded structural component according to the load loading file, the problems that the manual loading process is tedious, consumed time is long, and errors are likely to happen are solved. The working efficiency of loading the load for the structural member is improved, the loading error rate is reduced, and then the accuracy related to the subsequent vehicle performance is improved.
