Embodiment Construction

[0033] The multi-signal feedback loading and decoupling method and device for a structural test system according to an embodiment of the present invention will be described in detail below with reference to the accompanying drawings.

[0034] image 3 A structural testing system is shown having multiple loading channels in accordance with an embodiment of the invention. To simplify the description, image 3 Only three loading channels are shown in , and the cantilever beam is loaded by a valve-controlled cylinder. Such as image 3 As shown, a cantilever beam 301 as a bearing object is fixed on a base 303 through a supporting wall 302 . where u i (i=1, 2, 3) represents the control signal of the servo valve 304 on each loading channel, F i (i=1, 2, 3) represent the force signals collected by the force sensors 305 on the respective loading channels.

[0035] Specifically, when a certain loading channel i (i=1, 2, 3) applies a load F to the cantilever beam 301 i , the canti...

Abstract

The present invention provides a multi-signal feedback loading decoupling method for a structural testing system. The method comprises: linearly combining control signals from each loading channel and output load signals from each loading channel of multiple loading channels of the structural testing system to obtain decoupling compensation signals of each loading channel, to be used for compensating the control signals of each loading channel. The present invention also provides a multi-signal feedback loading decoupling device for the structural testing system.

Description

technical field [0001] The invention relates to a multi-signal feedback loading decoupling method and device for a structural test system. Background technique [0002] The structural test system refers to physically applying alternating loads to the body structure through the loading points all over the body of the aircraft, so as to observe the performance parameters of the body structure, so as to make a correct evaluation of the bearing capacity and fatigue life of the body structure of the aircraft. test system. Because multiple loading channels of the structural test system apply different loads to a load-bearing object at the same time, coupling interference will occur between the loading channels. [0003] In fact, the mutual coupling interference between the channels of the structural test system is a force closed-loop problem with external interference. At present, there are existing technologies on how to improve the control accuracy of the force closed-loop syst...
