Bidirectional loading soft real-time hybrid simulation test method and device

The invention discloses a bidirectional loading soft real-time hybrid simulation test method, which uses two MTS dynamic electro-hydraulic servo actuators which are horizontally arranged and have an included angle of 90 degrees in the loading direction to realize dynamic response simulation of a test substructure test piece under the action of bidirectional seismic waves through geometric relationconversion. The target machine provided by the invention uses a soft real-time loading method to provide more time for solving a numerical model and transmitting an actuator signal. If the solution cannot be completed within a given integration time step or the communication between programs is delayed, the hybrid simulation system can avoid the oscillation or deadlock of the system by increasingthe simulation time step length. 本发明公开了一种双向加载软实时混合仿真试验方法，本发明使用两台水平放置且加载方向夹角呈90度的MTS动态电液伺服作动器，通过几何关系转换实现了试验子结构试件在双向地震波作用下的动态响应模拟。本发明的目标机使用软实时加载方法，为数值模型的求解和执行器信号的传输提供了更多的时间。若未能在给定的积分时间步内完成求解，或者程序之间通信延迟，混合仿真系统可以通过增加仿真时间步长的方式避免系统
