Technical field
The utility model belongs to vehicle passive safety field tests, especially relates to dummy and chair motions displacement measuring device in a kind of vehicle collision testing experiment.
Background technology
In order to better evaluate the protective capability of vehicle to member, crash tests form is constantly perfect, thus more realistic traffic hazard form. new test form test speed is higher, and test chassis is heavier, and test angle also changes thereupon simultaneously.Such as 40% biased test, the little overlap test of SOP, multi-angle crash tests, RMDB crash tests etc.In common crash tests, dummy travels forward and is coming in contact with the constrained system such as air bag, and the way of contact is comparatively simple, is convenient to injury and analyzes.New crash tests is more harsh, and meanwhile, due to the change of angle, the deflection strengthened all can occur when being subject to clashing into vehicle, and test dummy also more complicated motion can occur, and comes in contact with the body part such as air bag, A post.And in this case the potential injury of human body will be increased greatly, the especially head of human body and neck.
In traditional frontal collision test, dummy can travel forward along vehicle X-direction after collision happens.The image gathered by high-speed camera can calculate displacement and the related dynamic parameters of dummy.At car in car and angle collisions, dummy also can produce moving of Y-direction along X while moving.Simultaneously during collision happens, seat also can occurrence dynamics position or even plastic yield, in order to measure the displacement of dummy and seat more accurately, be necessary the device designing a set of measurement dummy and seat dynamic displacement, the assessment for potential injury provides data foundation.
Summary of the invention
In view of this; the utility model is intended to propose dummy and chair motions displacement measuring device in vehicle collision testing experiment; combined with the performance degree of injury and constrained system by the dummy's dynamic displacement measured, thus can constrained system be optimized, improve vehicle to the protective capability of occupant.
For achieving the above object, the technical solution of the utility model is achieved in that
Dummy and chair motions displacement measuring device in vehicle collision testing experiment, comprise the stay wire displacement sensor 1 be installed on vehicle body, be installed in the seat 2 on vehicle body, be seated in the dummy 3 on seat 2, be installed in the support 4 on dummy 3 neck and drawstring 5 with a scale, described stay wire displacement sensor 1 is arranged on the vehicle body at seat 2 rear, the bracing wire end of described stay wire displacement sensor 1 is connected through the backrest back skeleton 6 of the backrest back connecting hole with seat 2 that are arranged on seat 2, described drawstring 5 one end is installed on support 4, the other end is connected with the backrest front surface skeleton 7 of seat 2 through the connecting hole on backrest front surface top being arranged on seat 2, described drawstring 5 two ends equal altitudes is arranged.
Further, described stay wire displacement sensor 1 is connected with the backrest back middle and upper part of seat 2.
Further, the backrest back of described seat 2 arranges multiple and described stay wire displacement sensor 1 along short transverse and is connected and uses connecting hole.
Further, described support 4 is L shape aluminium brackets.
Further, the bracing wire end of described stay wire sensor 1 is pasted onto on the backrest back skeleton 6 of seat 2.
Further, the bracing wire end of described stay wire sensor 1 is connected with the drag hook on the backrest back skeleton 6 being arranged on seat 2.
Relative to prior art, in vehicle collision testing experiment described in the utility model, dummy and chair motions displacement measuring device have following advantage:
Dummy and chair motions displacement measuring device in vehicle collision testing experiment described in the utility model, the displacement of seat can be measured, thus safety evaluation is carried out to it, obtain constrained system to the protective capability of occupant eventually through calculating, judge the risk of potential injury; Dummy's direction of motion and characteristic can be understood, obtain dummy's exercise data, potential injury can be assessed more accurately; The dummy's dynamic displacement measured will to injure with dummy and the performance degree of constrained system combines, thus can be optimized constrained system, improves vehicle to the protective capability of occupant.
