Device for ensuring position precision of radome test loading point

Abstract

The invention belongs to the field of test mechanics, and particularly relates to a device for guaranteeing the position precision of a radome test loading point, which comprises a loading assembly, asteel wire rope, an actuator and a stand column, wherein the loading assembly is composed of a load transfer pull rod, transfer lug rings and a canvas belt; the canvas belt is pasted on the surface of the test piece; the load transfer pull rod is provided with a limiting assembly and scales; and the two ends of the load transfer pull rod are connected with the transfer lug rings arranged on the canvas belt; one end of the steel wire rope is connected with the load transmission pull rod, and the other end of the steel wire rope is connected to the actuator. By adopting the device provided by the invention, stable and accurate loading in the radome load transfer process is realized, the installation of a radome static test system is facilitated, and the high efficiency, accuracy and stability of radome static test loading are ensured.

Description

technical field [0001] The invention belongs to the field of test mechanics, and in particular relates to a device for ensuring the position accuracy of a radome test loading point. Background technique [0002] Static test is a technical key to the design of radome. The technical agreement of GJB67 and various types of radome has put forward requirements for the static test of radome. At present, the loading method of the static test tensile load is mainly to use simple pull rods and steel wire ropes to transmit the test load. The simple pull rods are simple rods without limit design. Under the condition of large load, the steel wire rope will overcome the surface friction and slide on the simple pull rod, and deviate from the correct loading position, resulting in loading error. In addition, in order to ensure that the simple pull rod does not fall off during the test, its connection end needs to be fixed to the loading adapter device. In the early stage, adhesive tape wa...
