Problems solved by technology

The deflector used for missile launching has a relatively large bearing surface, which is a streamlined curved surface. Under working conditions, it bears the pressure of the gas flow as a whole, and the bearing part is made of non-metallic materials. No damage will occur during the test. The pressure applied by the test press cannot meet the above test requirements.

Embodiment

[0033] A certain type of deflector is a unilateral type of deflector structure (see Figure 5 ), the profile is a double inflection point arc surface, the forward projection size is 1200×1200mm, and the height is 370mm. It is required to have an overall bearing capacity of 40t. The test process must not damage the non-metallic surface. The test method includes the following steps:

[0034] 1) Install a strain sensor on each of the fourteen measurement points on the bottom surface of the deflector 1 to be tested, respectively bond the five vertical pull wires of the displacement sensor to the five measurement points on the bottom of the deflector to be tested, and all the strain sensors The signal line of the displacement sensor is jointed with the signal line of the displacement sensor and connected to the data collector together;

[0035]2) Assemble the deflector 1 to be tested after step 1) into the frame 4 on the top of the test bracket 2, and the assembly state of the defl...

Abstract

The invention discloses a flow director overall static load testing method for missile launching. A strain sensor is mounted on the bottom face of a to-be-tested flow director; a vertical wire of a displacement sensor is pasted to a measuring point at the bottom of the to-be-tested flow director; the to-be-tested flow director is assembled in an encircling frame at the top of a testing supportingbracket; a sandbag assembly is positioned in an accommodating cavity formed by the to-be-tested flow director and the encircling frame; a pressing plate assembly is positioned above the sandbag assembly and is connected with an oil cylinder system on the lateral face of the testing supporting bracket; adjusting is conducted before a test is carried out; and a plurality times of full-load tests areconducted. According to the flow director overall static load testing method for missile launching, testing data are reliable and stable, the product quality rick is low, the testing cost is low, testing conditions are easy to achieve, and damage to non-metal materials does not occur.

Description

technical field [0001] The invention belongs to the technical field of product static load test, and specifically refers to a method for static load test of an overall deflector for missile launching. Background technique [0002] At present, the static load tests of industrial and military products with load-bearing purposes are mostly realized by test presses. The test presses are rigid pressure, which can realize partial loading and simulated static load tests under single pressure conditions, suitable for small products or products. Static load test at local locations. The deflector for missile launching has a relatively large bearing surface, which is a streamlined curved surface. Under working conditions, it bears the pressure of the gas flow as a whole, and the bearing part is made of non-metallic materials. No damage will occur during the test. The pressure applied by the test press cannot meet the above test requirements. The deflector military manufacturing enterp...
