In the development process of the whole vehicle, the durability test of the whole vehicle is required to verify the durability of the heat insulation plate, and generally, the time of half a year is required.
In order to shorten the development period and reduce the failure risk of the thermal insulation board falling, the vibration durability of the thermal insulation board needs to be verified separately for the product development of the thermal insulation board, particularly for the thermal insulation board on a fuel tank without a binding band, but currently, no effective test device is available in the industry for testing, and the traditional whole vehicle verification method has the following defects:
1) the traditional finished automobile verification method has long experimental period and high cost;
2) in the traditional finished automobile verification, if the thermal insulation board falls off and fails, the optimized thermal insulation board cannot be verified quickly after the thermal insulation board is optimized, so that the development progress of the whole project is influenced;
3) the failure risk of the newly developed heat insulation plate cannot be verified at the early stage, so that the failure risk is higher in the verification of the whole vehicle; therefore, a new solution to solve the above technical problems is urgently needed.
