Attitude control device for running test stand

摘要

PROBLEM TO BE SOLVED: To control a test stand for use in a running test of a vehicle or the like to a required three-dimensional inclined posture by setting and inputting three variables including the yawing angle, pitch angle and rolling angle of the vehicle or the like.SOLUTION: A posture control device for test stand is equipped with: a test stand 12 that can be mounted with and support a vehicle or the like and keep it in a three-dimensional inclined posture; four universal joints 25 as supporting means for supporting the stand in a suspended state; four supporting columns 21 each having a screw shaft 22 and an elevating table 24 as elevating means to liftably support the test stand via the joints; a servo motor 23 with a numerical positioning function as driving means for controlling the up-and-down driving of these elevating means; and control means for controlling the driving of each of the driving means. The control means calculates the up-and-down driven extent of each elevating means by inputting such setting of the test stand as to take a desired three-dimensional inclined posture, and controls the driving of each of the driving means to perform required inclined posture control of the test stand.SELECTED DRAWING: Figure 1
