A method for manufacturing a seat for measuring a standard driving posture of a human body includes: performing three-dimensional scanning on an auxiliary device to acquire a first point cloud data set; constructing N seat curves according to the plurality of groups of displacement data sets; correspondingly processing the N seat curves and the first point cloud data set to delete the point cloud data above the seat curves so as to obtain a second point cloud data set; and performing inverse modeling on the second point cloud data set to obtain a rigid seat model for manufacturing a rigid seat. The rigid seat manufactured through the method facilitates putting a dummy in a standard driving posture and also can avoid the problem that key sizes of the dummy are not correctly measured due to deformation of the seat surface.

A method for determining a peak position of lower extremity injury in a crash test dummy includes: controlling the movement of the collision surface until the control point of the collision surface and the first designated collision point of the dummy's lower extremity form a line parallel to the direction of the vehicle acceleration, with a predetermined distance between the control point and the first designated collision point. A collision simulation calculation is performed to obtain the first tibial index curve, the first knee displacement curve, and the first thigh force curve. Similarly, the second designated collision point is used to obtain the second tibial index curve, the second knee displacement curve, and the second thigh force curve. Then, the injury values are calculated, and by comparing the injury values at different positions, the peak position is determined.
