Title:
DISPLACEMENT-CURRENT HYBRID CONTROL QUASI-STATIC TEST LOADING SYSTEM
Document Type and Number:
WIPO Patent Application WO/2021/081690
Kind Code:
A1
Abstract:
A displacement-current hybrid control quasi-static test loading system, which provides a loading system and method for a quasi-static test of a self-reset structure provided with a magnetorheological damper. The method comprises the following steps: S1. determining an active control parameter used for an actuator, the parameter comprising multiple stages of loading displacement angles, the quantity of cyclic loading cycles at each stage of loading displacement angles, and the period of each cyclic loading; S2. determining a semi-active control parameter used for a regulated direct current power supply, the parameter comprising the current level, the current application moment, the current duration, the change in current or termination moment, as well as the quantity of current levels of a magnetorheological damper; and S3. inputting the parameter determined in S1 into the actuator, and inputting the parameter determined in S2 into the regulated direct current power supply. In the described loading system, the rigidity, bearing capacity, and energy consumption performance of the self-reset structure can be increased by continuously applying a current. After a test, the current is cut off, thus eliminating the impact of the magnetorheological damper on the self-reset performance of the self-reset structure.
