The invention relates to a synchronous control system of a multi-cylinder loading testing machine. The synchronous control system comprises a base, a synchronous control system body and supporting columns arranged at the upper end of the base, and further comprises a beam arranged at the upper ends of the supporting columns. The synchronous control system further comprises a fixed chuck and a movable chuck which are arranged between the base and the beam. A force measuring sensor arranged between the fixed chuck and the base is further included. The synchronous control system further comprises oil cylinder barrels arranged on the side faces of the supporting columns. Pistons penetrating the oil cylinder barrels are further included. According to the synchronous control system of the multi-cylinder loading testing machine, the moving displacement of the pistons is collected through magnetic induced telescopic displacement sensors, the opening amount of servo valves corresponding to oil cylinders is adjusted through the synchronous control system body, the opening amount of the servo valves corresponding to the oil cylinders with the large piston displacement needs to be properly reduced, on the contrary, the opening amount of the servo valves corresponding to the oil cylinders with the small piston displacement needs to be properly increased, and balance can be achieved so as to achieve the purpose of synchronous control.
Description
technical field [0001] The invention relates to the technical field of scientific measuring instruments, in particular to a synchronous control system of a multi-cylinder loading testing machine. Background technique [0002] In today's rapid economic development, no matter government agencies, national defense science and technology departments, enterprises, colleges, or ordinary consumers have higher and higher requirements for product performance, appearance, performance, quality and cost, especially It is the reliability of product quality that has higher requirements. For the instrumentation production industry that detects product quality and product raw material performance, it is facing better opportunities and development, but also facing new challenges. The traditional multi-cylinder loading testing machine is reduced due to the low synchronization accuracy of the control system. It is difficult to meet the experimental needs of today's era due to the loss of prod...
