The invention relates to the technical field of mobile impact test, in particular to a simple support and clamped support combined mobile impact wheel load test device and a test method. The device comprises a base assembly; a truss pier assembly and a support pier assembly are arranged on the base assembly; a truss is arranged on the truss pier assembly; a mobile impact assembly is arranged on the truss; a simple support and clamped support clamp shaft is arranged on the support pier assembly; a test piece plate is arranged on the simple support and clamped support clamp shaft; a strain gauge and a displacement meter are arranged on the test piece plate; and the mobile impact assembly and the test piece plate are arranged correspondingly. By adoption of the structure arrangement, the mobile impact assembly is arranged on the truss, the simple support and clamped support clamp shaft is arranged on the support pier assembly, the test piece plate is arranged on the simple support and clamped support clamp shaft, and the mobile impact assembly performs impact on the test piece plate so as to acquire test data; and the simple support and clamped support combined mobile impact wheel load test device is simple in structure, convenient to operate and reasonable in manufacturing and operating cost, and can perform mobile impact test in a laboratory.
Description
technical field [0001] The invention relates to the technical field of mobile impact tests, in particular to a mobile impact wheel load test device and test method combined with simple support and fixed support. Background technique [0002] Many engineering problems involve the problem of moving impact. For example, when an airplane lands, it usually produces a large impact on the ground first, and is accompanied by the forward movement; when the vehicle is driving on an uneven bridge, it will also appear The problem of moving impact is a very important engineering problem that needs to be responded to both the dynamic response of the bridge and the impact force of the vehicle during the moving impact process. When a carrier-based aircraft lands on a ship, it is usually accompanied by a severe impact and moves forward at a high speed. It produces a huge impact force on the ship deck. However, for the experimental research on the impact deck of the carrier-based aircraft, at...
