[0086] [Example 2]
[0087] Figure 8 It is a schematic configuration diagram showing a motor vehicle crash simulation test device of Example 2 of the present invention. It should be noted that components having the same functions as those in the above-mentioned embodiments are denoted by the same reference numerals, and detailed descriptions are omitted.
[0088] In the vehicle crash simulation test device of Example 2, such as Figure 8 As shown, the stroke of the piston 32 in the hydraulic cylinder 22 is set based on the data obtained through the actual vehicle collision test, and the stroke start position of the piston 32 is set based on the stroke. That is, as in Example 1, the stroke of the piston 32 is set based on the data obtained through the actual vehicle crash test, and the stroke start position of the piston 32 is set based on the stroke. Then, the piston 32 is moved from the initial position to the strike start position, and the collision simulation test is performed...
