The invention discloses a thighbone angle adjustment device and adjustment method of a pedestrian protection thigh impactor, comprising a first positioning bolt, a second positioning bolt and a base; the base consists of a flat plate, a first lug and a second lug Composition, the base mounting hole is opened on the plate, the first positioning screw hole is opened on the first lug, the second positioning screw hole is opened on the second lug, the first positioning bolt is screwed with the first positioning screw hole and connected with the The first lug is vertical, and the second positioning bolt is screwed to the second positioning screw hole and is perpendicular to the second lug; before the first test, the base is fixedly connected between the launching block and the thigh connecting seat, and then Move the first and second positioning bolts; after a test, first loosen the thigh connecting bolts, then tighten the first and second positioning bolts, then tighten the thigh connecting bolts, and finally loosen the first and second positioning bolts. The invention can quickly and accurately complete the adjustment of the femur bone angle after the collision, and improve the test efficiency and precision.
Description
Technical field[0001]The invention belongs to the field of pedestrian protection thigh tests, and in particular relates to a thigh bone angle adjustment device and an adjustment method of a pedestrian protection thigh impactor.Background technique[0002]Pedestrian protection thigh impact test is used to evaluate the injury of the human pelvis after a pedestrian collides with a vehicle. The dummy module used in the test is a pedestrian protection thigh impactor required by regulations. Such asfigure 1 As shown, the pedestrian protection thigh impactor includes a thigh rear end module 7, a thigh connecting seat 5, a bending moment sensor 9, a thigh bone 8, a thigh connecting bolt 6 and a force sensor 10. The thigh bone 8 has a cylindrical structure, and the back of the thigh The end module 7 is a cuboid, the thigh rear end module 7 is parallel to the thigh bone 8 and fixed together by bolts, the thigh rear end module 7 and the thigh connecting seat 5 are fixedly connected by the thigh ...
