Problems solved by technology

[0003] At present, there have been some studies on the simplified calculation method of the joint structure itself, all of which are to simplify the existing body joint structure, and obtain the structural performance of the joint through the calculation of the defined local bending and torsional stiffness, and perform local optimization of the joint according to the performance. It is impossible to accurately evaluate the influence of joint structure changes in different parts on the performance of the vehicle
