Title:
制振ダンパの試験装置
Document Type and Number:
Japanese Patent JP7309288
Kind Code:
B2
Abstract:
To provide a vibration damper test device capable of inputting displacement of an actuator into a vibration damper while amplifying it while keeping an amplification factor input to the vibration damper constant, and performing test satisfactorily by accelerating vibration performance.SOLUTION: A test device 1 includes not rotatable movable first and second movable bodies 3A, 3B and a ball screw mechanism 5 for amplifying relative displacement of the vibration damper 21. The ball screw mechanism 5 includes a first and a second nuts 10A, 10B provided on the first and second movable bodies 3A, 3B, and a rotatable immovable screw shaft 11 having first and second screws 12A, 12B constituting first and second ball screws 13A, 13B therewith. The first and second ball screws 13A and 13B have an inverse screw relationship. A vibration damper 21 is disposed between the first and second movable bodies 3A and 3B. An actuator 4 vibrates the vibration damper 21 via the first movable body 3A.SELECTED DRAWING: Figure 1
