Space positioning and supporting device for actuating cylinder

Abstract

The invention belongs to a strength test loading and supporting technique, and particularly relates to a positioning and fixing device required for the mounting of actuating cylinders. The main body of a space positioning and supporting device for the actuating cylinders is a frame plate, a plurality of mounting holes are formed in the frame plate, and every four mounting holes form a set to be used for fixing the actuating cylinders, and each set corresponds to the mounting position of one actuating cylinder under all working conditions. The frame plate is formed by welding channel steel and a steel plate, wherein the thickness of the steel plate and the specification of the channel steel are determined by loading point loads based on the number of the actuating cylinders arranged on the frame plate. The space positioning and supporting device for the actuating cylinders, disclosed by the invention, can enable a plurality of actuating cylinders to be quickly and conveniently positioned and reloaded, and support the integration of the actuating cylinders, so that the labor intensity and the mounting risk are greatly reduced, and the working efficiency is improved; in addition, a welding general frame structure is adopted, the requirements for the position and the mounting of the tested actuating cylinders are effectively met.

Description

Technical field [0001] The invention belongs to the strength test loading support technology, and specifically relates to a positioning and fixing device required for the installation of an actuator. Background technique [0002] Loading the test piece through the actuator is the main method used in the aircraft ground strength test to simulate the actual loading of the aircraft. With the increase in requirements for the test load to be closer to the real load situation, the load situation will inevitably be more complicated and the test conditions will be more, which will lead to the increasing number of actuators used in the aircraft ground strength test; on the other hand, due to the aircraft Due to the high cost and long period of test piece development, it is usually desirable to complete as many strength test assessment items as possible on one test piece. As a result, a test often contains multiple test load conditions; again, due to the error of the actuator installation ...

AI Technical Summary

Problems solved by technology

The whole refitting process will inevitably lead to unfavorable factors such as the use of many equipment and personnel, large amount of high-altitude operations, large equipment occupation, mutual interference, large installation errors, and inconvenient inspection of installation results.

It makes the coordination of test design difficult, the test duration is long and affects the test loading accuracy
