Due to the change of the structure of the lower beam to the closed section structure, the structure of the X direction is mainly changed, which can explain that the dynamic stiffness in the X direction has undergone a significant change before and after the simulation test; at the same time, the lower beam of the radiator and the inner side of the left and right columns Adding a connecting plate respectively, a small triangle-like structure is formed between the lower cross member of the radiator, the left (right) post, and the connecting plate, so that the stability of the radiator frame structure is improved, and the stiffness is improved. This triangular structure affects the dynamic stiffness of the radiator in both the Y and Z directions, but because the two triangular structures in the Y direction are symmetrical, the effects may cancel each other, and the two triangles in the Z direction produce The influence is consistent, and then superposition may occur, which ultimately leads to significant changes in the dynamic stiffness in the Z direction in the test results, while the stiffness in the Y direction is almost constant. But from the results of the entire test, the stiffness of the improved radiator frame will be improved, and the dynamic stiffness of each installation point will also be improved. Further verification of the test test needs to be verified by the actual vehicle. In addition, in order to improve the test success of the actual vehicle and reduce the test cost, in the follow-up test verification, we can increase the size of the connecting plate to form a more solid and reliable triangular auxiliary structure and increase the connection. The number of plates (upper beam) and other reference methods are used to further simulate and verify the dynamic stiffness performance of each mounting point.
The prediction of the lack of stiffness of the engine room radiator frame in a certain type of vehicle, the analysis of the reasons and the optimization design process description, the use of the actual vehicle test results of the old model to analyze the possible problems of the new model, combined with the CAE finite element analysis method in the design stage, can be very good Predict the possible problems of new models, so that appropriate measures can be taken to improve the body design stage, shorten the production and development cycle for the development of new models, while saving production resources and increasing production efficiency. Therefore, the idea of â€‹â€‹design and development in this way will be an important reference direction for the development of subsequent models.
