Abstract

The invention relates to a test bed, which comprises a frame and a first test part for impact test of an automobile door. The first test part comprises a first rope pay-off and take-up mechanism, a pull cable mechanism, an elastic mechanism and a first monitoring mechanism, wherein the first rope pay-off and take-up mechanism is sued for opening an automobile door, the pull cable mechanism is used for unlocking the automobile door, the elastic mechanism is used for applying elastic force to the automobile door to close the same, the first monitoring mechanism is used for monitoring impact of the automobile door in closing, the first rope pay-off and take-up mechanism, the pull cable mechanism, the elastic mechanism and the first monitoring mechanism are respectively disposed on the frame, and the first monitoring system comprises a first angular speed sensor disposed on the edge of the automobile door. The test bed can be used for precisely controlling impact speed, so that accuracy of data testing is improved, and reliability of the test bed is improved.

Description

【Technical field】 [0001] The present invention relates to a test device, and more particularly, the present invention relates to a test device for acquiring collision impact energy when testing the closing of vehicle doors, hoods and trunk lids. 【Background technique】 [0002] At present, vehicles are more and more commonly integrated into the lives of ordinary families. The cost performance of vehicles has become an indicator that ordinary families pay close attention to when purchasing vehicles. [0003] Doors, hoods and trunk lids are indispensable working parts of the vehicle. Their technical level and quality can reflect and reflect the technical and quality level of the entire vehicle to a large extent. Both users and manufacturers must face up to it. and concerns. However, as far as OEMs are concerned, "excessive" design is also unintentional. After all, "excessive" design means increased costs and waste of resources. Therefore, the entire industry and enterprises ...
