Japan, March 5 -- SINFONIA TECHNOLOGY CO LTD has got intellectual property rights for 'VEHICLE COLLISION TEST DEVICE.' Other related details are as follows:
Application Number: JP,2022-027035
Category (FI): G01M17/007@Z,G01M7/08@A
Stage: PROBLEM TO BE SOLVED: To solve the problem that the vehicle speed deviates from a predetermined speed at a separation position of a vehicle by feeding back the traction speed at the position where the influence of expansion and contraction of a traction rope is minimized.SOLUTION: A vehicle collision test device includes: a traction rope 1; a drum 2 for pulling the traction rope 1; a plurality of sheaves 3 (3A, 3B) engaged with the traction rope 1; a motor 4 for driving the drum 2; and control means 5 for controlling the motor 4 based on a traction speed command Vref. In a collision test in which a vehicle 7 is connected to a connection point C set on the traction rope 1 via a dolly 6, which is connection/disconnection switching means, a sheave speed detection part 31 is installed on the sheave 3B at a position closest to the connection point C of the vehicle, and the sheave speed Vs detected by the sheave speed detection part 31 is inputted to the control means 5 to control the motor 4.SELECTED DRAWING: Figure 1 (Grant)
