Problems solved by technology

Although the above scheme can determine whether the performance of vehicle components meets the design indicators under different working conditions, the process of simulation analysis takes a long time and the work efficiency is not high. Moreover, with the increase of the number of working conditions, the data volume of the vehicle component model It is getting bigger and bigger, which leads to the shortage of data storage space occupied and damages the user experience
