Motor/air-hydraulic load simulator system

Abstract

The invention provides a motor / gas-liquid load simulator system which comprises a base, three supports (2, 11 and 12), a locating base, a gas-liquid cylinder (4 and 5), a displacement sensor, a coupler, a pressure sensor, a crank rocker and a motor. The base bears the whole system elements, the gas-liquid cylinder (4 and 5) is formed by connecting a hydraulic cylinder and a pneumatic cylinder in series, the displacement sensor is a resistor telescopic position sensor or one of other linear position sensors, the coupler is used for connecting the two ends of the crank rocker and the two ends of a gas-liquid cylinder connecting rod and the pressure sensor is a pressure type sensor. According to the motor / gas-liquid load simulator system, the fact that gas has high compressibility is considered, the flexibility of the system can be improved, the liquid part can provide appropriate damping, liquid has the characteristic of high rigidity and the gas and the liquid are combined, so that a simulator has the advantage of being rigid and flexible at the same time. Thus, the motor / gas-liquid flexible loading system used for simulating loads has the advantages of being stable in running, high in precision, strong in flexible loading characteristic and the like, and the key characteristics of the load simulator are improved.

Description

technical field [0001] The patent of the present invention belongs to the technical field of simulators, in particular to a load simulator system. Background technique [0002] The load simulator is a device that simulates the moment load required by the bearing object under test conditions. It can simulate the soil resistance encountered by agricultural machinery during plowing operations; it can simulate the aerodynamic force of aircraft landing gear at different flight heights and speeds; it can simulate the load of seawater on submarine antennas; it can simulate the process of lifting large lifts The load force; it can simulate the dynamic load of tanks and cars on different road surfaces; it can simulate the muscle force of the biological manipulator; it can simulate the traction force and braking torque of the power unit, etc. Through the load simulation of the load simulator, the destructive or destructive full-body experiment is transformed into a semi-physical simu...

AI Technical Summary

Problems solved by technology

The hydraulic load simulator has high operating accuracy, but its movement speed is slow; the electric load simulator has a small output torque; the pneumatic load simulator has poor operating accuracy and low stiffness

At present, there are not many reports on the literature on the motor / pneumatic-hydraulic load simulation system. As far as the inventor knows, there are almost no patent documents on the motor / pneumatic-hydraulic flexible loading system.
