Carefully analyze the extrusion of the wiring harness in the simulation results, and give a comprehensive judgment; for the combination 16, the CAE simulation results are low, and it can be considered that if the CAE analysis in the early design will not exceed the standard, then in the later test verification, generally not. Exceeding the target value will occur; the CAE simulation results in combination 22 are compared with the test results, and the stiffness of the wire harness is high in the front and low in the back. Overall, it can be considered that the stiffness of the wire harness has little deviation from the test. However, the stiffness of the rear section of the combined 22 CAE simulation results is low. Therefore, when the target value of ≤70% is used for CAE design evaluation, the risk of the result is controllable. Of course, in order to prevent very few omissions, it is still necessary to combine engineering Experience careful analysis of CAE results. Comprehensive analysis of all the benchmarking results, it can be basically judged that the CAE simulation method and the wire harness evaluation target value obtained by the test can be used for the wire harness collision protection design.
