Abstract

The invention discloses an aerial cabin door lock variable loading test device, composed of a fixing component, a transmission component, a driving component and a loading component, wherein the loading test device is fixedly connected with external equipment and a test object through a fixing plate, a control system sends an actuation signal to a hydraulic system during the test to make the driving component and the transmission component operate so as to apply different loads to the test object at different working stages and simulate the test object to move to the final locked position; anda spring is used as the load tool to obtain high loading accuracy. The test device has compact structure and large rigidity, the test is completed by a single drive actuator, and less demanding is required for the hydraulic system; the position of the test object is adjusted by a positioning sleeve, and the operation is simple; the test object is not blocked, which is beneficial to observation for work process of the test object; and the production and processing are less difficult, thereby having better engineering application prospects.

Description

technical field [0001] The invention relates to an aviation cabin door lock test device, in particular to a variable loading test device for an aviation cabin door lock. Background technique [0002] A test fixture is a device used to support a test object during a test. In the process of reliability and durability testing, in addition to providing support to the test object, it is also necessary to provide a periodic driving force for the movement of the test object. The working process of the test fixture should meet the working environment that can be simulated as much as possible; at the same time, the reliability and durability tests are assessed for small samples, and the test fixture must have high strength and rigidity, and can meet the requirements for cyclic loading. The more realistic the test fixture simulates the real use environment, the more likely the potential deficiencies will be exposed during the test, and the problems reflected will be more credible. ...
