Positioning Control System for Full-Scale Aircraft Static Tests

摘要

PURPOSE: A position posture control apparatus is provided to reduce manufacturing cost and obtain accurate control characteristics by using hydraulic/pneumatic components. CONSTITUTION: A position posture control apparatus comprises a hydraulic operator(1) which restricts six degree-of-freedom for restricting rigid motion of a testing object(9). The load applied to the testing object is transmitted to a hydraulic pressure portion of the hydraulic operator attached to the testing object, so as to generate a pressure. The pressure corresponding to the volume of load which is pre-calculated with respect to the pressure generated at the hydraulic operator, is absorbed, through a pipeline, to a first pressure regulator(5) of a pressure regulator(2) arranged within a control unit(10). The pressure is absorbed linearly in accordance with the compression ability of an air pressure controller(4) for controlling air pressure of a pressure accumulator(3), when the pressure is greater than the calculated load. Thus, the hydraulic operator having six degree-of-freedom performs simulating motion. When the linear displacement of the hydraulic operator occurs, a single direction flow unit(6) operates so as to permit position change of the hydraulic operator. Thus, the control unit of different five systems operates, to thereby restrict the rigid motion of the testing object.
