Separation-type hybrid test system and test method

Abstract

The invention relates to a separation-type hybrid test system and a test method. The separation-type hybrid test system comprises an OpenSees numerical substructure module, a MATLAB computing module,an ARM embedded controller module, a data acquisition module, an actuator loading system and a test substructure module. In addition, the test method based on the separation-type hybrid test system isfurther disclosed. OpenSees, MATLAB and the ARM embedded controller are combined, thus the functions of real-time two-way communication between the OpenSees and the MATLAB and real-time two-way communication between the MATLAB and the ARM embedded controller are realized, the problem of cooperative work of a numerical simulation test of the OpenSees numerical substructure module and a real objecttest of the test substructure module in the overall structure is solved, and a hybrid dynamic simulation seismic test of a damping structure can be realized. The separation-type hybrid test system and the test method further have the characteristics that the test system is small in occupied area, low in cost and high in test precision, the test procedure is easy to transplant, and the test systemis easy to control.

Description

technical field [0001] The invention relates to a separate hybrid test system and a test method, belonging to the technical field of anti-seismic tests of civil engineering structures. Background technique [0002] In the field of anti-seismic test of civil engineering structures, the traditional anti-seismic test methods of structures mainly adopt the test methods of pseudo-static test, pseudo-dynamic test and shaking table test. The pseudo-static test applies a predefined displacement to the specimen through the actuator, so as to obtain the basic information of the specimen, such as stiffness, bearing capacity, deformation and energy dissipation capacity. This method is easy to operate and the results are easy to compare and analyze, but this method cannot reflect the response of components under real earthquake action, so this method cannot be used to study the performance of velocity or even acceleration-related components. The pseudodynamic test method combines the co...

Problems solved by technology

Among them, OpenFresco is mainly an interface software developed for OpenSees software. It has only developed several conventional test units and lacks complex special test models, which greatly limits the application of OpenSees numerical simulation software in hybrid test systems. MTS electro-hydraulic The servo loading system is a large-scale hydraulic servo system. The system has high requirements for the scale of the laboratory, the capacity of the test equipment, the number and performance of computers, and the number of personnel in various aspects. The whole system is complex to build, and its singleness and high Costs make hybrid testing systems prohibitively expensive and a major barrier to the adoption of this advanced testing method
