Abstract

The invention relates to a dynamic and static multifunctional test servo loading system, and belongs to the technical field of civil engineering. The system includes a steel reaction force platform, areaction force wall, a rigid cross type load beam and a dynamic actuator. The reaction force wall includes a first reaction force wall 1 and a second reaction force wall 2 at an angle of 90 DEG. Thedynamic actuator includes a plurality of horizontal dynamic actuators and a plurality of vertical dynamic actuators. The horizontal dynamic actuators are respectively connected with the reaction forcewall and the rigid cross type load beam. The vertical dynamic actuators are respectively connected with the steel reaction force platform and the rigid cross type load beam. The system component of the system can be freely disassembled to form a test servo loading system with different functions, and can realize free switching of static multi-dimensional loading, dynamic multi-dimensional loading, vertical high-speed impact loading and ocean wave simulation loading systems through disassembly and connection and the control actuators. The system can greatly save investment of manpower and material resources, and is a multifunctional test servo loading system which is reasonable in design, and is efficient and convenient, and can be dismounted freely.

Description

technical field [0001] The invention relates to a dynamic and static multifunctional test servo loading system, which belongs to the technical field of civil engineering. Background technique [0002] In recent years, earthquakes have occurred frequently, and secondary disasters such as large earthquakes, intensive earthquakes, and accompanying or triggered tsunamis, debris flows, etc. will cause serious damage to sea and land infrastructure engineering structures; in addition, accidental events such as traffic accidents and terrorist attacks will also damage infrastructure structural components. Causes damage and destruction, and is difficult to repair, resulting in significant economic losses and threatening life safety. There is an urgent need for a simulation test platform that can truly simulate the mechanical behavior of the structural system and structural components under the action of earthquakes, tsunamis, vehicle and ship collisions, explosions, and impacts. Howe...
