Load sensitive valve-controlled integrated load loading device and control method thereof

Abstract

The invention provides a load-sensitive valve control integrated load loading device and a control method thereof. The loading device comprises a loading actuator module used for conducting loading on a to-be-tested device, an oil supplying module used for providing power for the loading actuator module, and a load-sensitive module used for controlling the working state of the oil supplying module. The loading actuator device module, the oil supplying module and the load-sensitive module are integrated. According to the load-sensitive valve control integrated load loading device, the loading actuator device module, the oil supplying module and the load-sensitive module are integrated, so that distributive loading can be realized, complex pipeline arrangements at multiple-passage loading test time are reduced, the loading device is made to be arranged flexibly, and the workload of changing the test table layout and structure is reduced. The load-sensitive module is used for controlling the working state of the oil supplying module, so that the efficiency of a hydraulic system is improved, energy consumption is reduced, and utilization cost is saved.

Description

technical field [0001] The invention relates to the technical field of electro-hydraulic servo control, in particular to a load-sensitive valve-controlled integrated load loading device and a control method thereof. Background technique [0002] The whole machine structure test system of the aircraft is mainly oriented to full-scale structural static test and fatigue / damage tolerance test. The static test is to study the static characteristics of the structure such as strength, stiffness and stability under the action of static load; the fatigue / damage tolerance test is based on the flight profile actually used by the aircraft, and the test load spectrum is compiled, and the test machine is cyclically loaded, exposed The key parts of structural fatigue damage provide the basis for fatigue life determination, repair cycle determination and improvement optimization. [0003] There are often dozens of loading points during the static test of the whole aircraft, which are respe...

Problems solved by technology

The static test needs to simulate different flight states, and the layout and configuration of the test bench are often changeable. It takes dozens of people nearly two weeks to change the configuration once, and the workload is huge.
