Mechanical loading mechanical experimental system and application method

Abstract

The invention discloses a mechanical loading mechanical experimental system and an application method. The system is composed of a carrying system, a movable loading system, a pressurizing system anda fixing system. The carrying system is composed of an upper bearing track, a lower carrying beam and a middle connecting rod; the movable loading system is composed of a carrying wagon box, a movablecontrol device and a counter weight; the pressurizing system is composed of a traction pull rod, a loading pressure head, a force sensor, a counterforce pressure bearing plate, an experimental carrying table, an experimental carrying table support column and a linking rod; and the fixing system is composed of a limiting pulley, a fixed support, a pin roll and a limiting blocking beam. In a usingprocess, by wirelessly operating the carrying wagon box on the carrying track, the whole truss structure can rotate along a fulcrum, so that the linking rod links the traction pull rod to provide a stair load or a long-term stable load to a test piece. By means of the lever principle, the truss structure which is unlikely to deform is adopted, so that the load stability is ensured; the limiting pulley is assembled, so that the pressurizing direction is ensured; the system is integrally mounted underground, so that the experimental safety is ensured; and the system is convenient to mount, simple to operate and suitable for the experimental field of engineering mechanics.

Description

technical field [0001] The invention relates to the field of mechanical experiments, in particular to a mechanically loaded mechanical experimental system and a using method. Background technique [0002] With the development of my country's economy and society, research in various engineering and technical fields continues to deepen, and carrying out experiments on the mechanical properties of materials is an indispensable part of scientific exploration. Therefore, various electro-hydraulic servo mechanics experiment machines have also been promoted one after another. The traditional electro-hydraulic servo testing machine can generate large eccentric and axial loads, but due to the fluidity of the hydraulic oil in the cylinder and the permeability of the cylinder mouth, the generated load cannot tend to be stable for a long time, and there is an upper limit for the pressure holding time. Therefore, its pressure-holding accuracy is limited by the hydraulic servo system duri...
