Falling object impact test apparatus and cab integrated test system

Abstract

The invention discloses a falling object impact test apparatus (2). The falling object impact test apparatus (2) comprises: a support (21); a third stay cable (23), which is arranged on the support (21); and a drop hammer (24), which is fixed on the third stay cable (23); besides, the falling object impact test apparatus also comprises a guiding framework (25), which is fixed on the support (21) and is vertically arranged along a falling path of the drop hammer (24). In addition, the invention also discloses a cab integrated test system including a testing stand and the falling object impact test apparatus (2); and the support (21) is installed on the testing stand. According to the above-mentioned technical schemes provided in the invention, the guiding framework that is vertically arranged along the falling path of the drop hammer can effectively guide the drop hammer to be always maintained at a vertical direction, so that the drop hammer can fall at a predetermined position accurately; and moreover, working personnel will not be harmed.

Description

technical field [0001] The present invention relates to a test device, in particular to a falling object impact test device, and also to a cab comprehensive test system with the falling object impact test device. Background technique [0002] The cab of a vehicle (especially an engineering vehicle) and the protective structure of the cab need to undergo a series of performance tests to ensure that the cab and its protective structure meet the relevant requirements. These performance tests include frontal impact tests, falling object impact tests, side tipping tests and crush tests, among others. [0003] The falling object impact test is performed by a falling object impact test device. The existing falling object impact test device usually includes a bracket, a guide wheel fixed on the bracket, a cable straddling the guide wheel and a drop weight fixed on the cable. During the test, the cab to be tested is set under the drop weight, the drop weight is pulled to a predeter...

AI Technical Summary

Problems solved by technology

When using this existing falling object impact test device to carry out the falling object impact test, when releasing the falling weight, if a lateral force is applied to the falling weight, the falling weight may deviate from the vertical direction during the free fall process, thus causing the falling weight to fall. The position where the hammer falls on the top of the cab will deviate from the predetermined position, which will affect the test results, and if the hammer falls to a position other than the cab, it will cause personal injury to the staff on site
