Embodiment Construction

[0056] The specific implementation manners of the present invention will be further described in detail below in conjunction with the accompanying drawings.

[0057] Such as figure 1 As shown, the present invention has designed a kind of hybrid test control system based on hydraulic actuator, including OpenSees-Matlab host computer module, numerical substructure module, STM single-chip controller module, hydraulic actuator loading device, magnetostrictive displacement Sensors, pull and pressure sensors and test substructures.

[0058] Such as figure 2 As shown, a hybrid test control system based on hydraulic actuators uses the hydraulic actuator as the actuator loading device (that is, the power source of the entire system) to realize the loading of the excitation signal of the test substructure; The structure is a test load, which realizes the force response and displacement response under the excitation signal, and is measured by a force sensor and a displacement sensor. ...

Abstract

The invention relates to a hybrid test control system based on a hydraulic actuator and a test method. The system comprises a numerical value substructure module, a Matlab calculation module, an STM32single-chip microcomputer controller, a hydraulic actuator loading device, a data acquisition module and a test substructure module. According to the system, hydraulic loading equipment is used as anexcitation source of the hybrid test system. An STM32 single-chip microcomputer controller is used for controlling hydraulic loading equipment, and OpenSees-Matlab software, a serial port communication technology, a feedback algorithm, a displacement sensor, a force sensor and the like are used for building a set of complete hybrid test system comprising a software program and hardware equipment.According to the invention, the problems of low precision and time delay of experimental equipment in a traditional electric vibration exciter hybrid test system are solved, the stability and test precision of the whole set of test equipment are improved, and the test loading reaction time is shortened. The test system has the characteristics of wide test working conditions, easiness in test program transplantation and easiness in test system control.

Description

technical field [0001] The invention relates to a hybrid test control system and test method based on a hydraulic actuator, belonging to the technical field of anti-seismic tests of civil engineering structures. Background technique [0002] Earthquake has always been one of the most harmful natural disasters to human life and property. The occurrence of earthquakes is uncertain. At present, human beings cannot realize accurate prediction of earthquakes, which makes the disasters caused by earthquakes to human society continue. In the past century, according to incomplete statistics, the death toll caused by the earthquake has reached more than 1.5 million worldwide, among which China has reached more than 500,000. People have gradually realized the importance of improving the seismic performance of building structures from earthquake disasters. As for earthquake disasters, currently using effective structural seismic design methods is a practical and feasible solution to ...
