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 impact test on a lower abdomen of a vehicle crash test dummy includes: controlling an arc-shaped hammer head to impact a lower abdomen of a preset dummy at a preset speed; obtaining displacements from a displacement sensor, wherein the displacements are generated by the lower abdomen of the preset dummy and the arc-shaped hammer head during the impact; obtaining a pressure from a pressure sensor, wherein the pressure is borne by the lower abdomen of the preset dummy during the impact; and determining, based on the displacements and the pressure, whether the preset dummy satisfies a biological simulation standard. The method is capable of testing whether the current dummy satisfies the biological simulation standard, so as to ensure the accuracy of test data in subsequent vehicle crash tests using the dummy.
