[0007] (2) In the fixed support state of a certain type of fairing, there are many explosive bolt devices and hinge devices lower than the fixed support plane in the required state of the test piece. How to facilitate its on-site installation and the implementation of the fixed support boundary, the design of the fixed support tooling is more difficult Big

Embodiment approach

[0061] Step 1: Fix the tooling, this step is common knowledge, as attached Figure 4 shown;

[0062] Step 1.1: According to the distribution position and size of the protrusions at the docking surface of the fairing 11, the form of the docking surface and the distribution size of the docking holes, determine the circumference of the punching hole 15 and the position of the through hole 16 for avoiding the structural interference of the docking surface;

[0063] Step 1.2: According to the space size required for assembly and docking operation of the fairing 11 test site, determine the size of the through hole 16 for avoiding structural interference of the docking surface to be 370mm×350mm;

[0064] Step 1.3: Determine the inner diameter 13 of the tooling and the outer diameter 14 of the tooling according to the distribution of the ground rails on the ground of the second floor F-2 in the vibrating tower and the distance between the ground rails of 1m; in order to maximize the u...

Abstract

The invention discloses a method for two-stage fairing-mounted rocket body free boundary implementation and fairing fixed-end boundary implementation in a vibration tower. The method for two-stage fairing-mounted rocket body free boundary implementation comprises the steps that a free suspension tool is arranged, a rocket body and a fairing are hoisted to a tower body in sequence, the fairing is connected with the rocket body in a butt joint mode, the installing position of a basket is determined, the fairing is separated, and half baskets of the basket are fixed. The method for fairing fixed-end boundary implementation in the vibration tower comprises the two steps of fixed-end tool implementation and fixed-end boundary implementation. Compared with the prior art, the method for two-stage fairing-mounted rocket body free boundary implementation and fairing fixed-end boundary implementation in the vibration tower has the advantages that the test preparation period is short, available resources are effectively utilized, the test cost is reduced, and the test risks are reduced through the matched risk handling scheme.

Description

Background technique [0001] The structural dynamic characteristic test is a routine and important link in the product development process. The general purpose of the test is to assess the dynamic characteristic parameters of the structure in the real state of the product; for launch spacecraft and missile weapons, it can provide attitude control The important design parameters of the stable system can also provide important parameters for theoretical prediction model correction; it can also be used for structural health detection and discovery of structural design defects, etc. The boundary condition of the product is a decisive factor to determine the dynamic characteristic parameters of the structure. Therefore, how to realize the specific boundary conditions of the test product safely, efficiently and at low cost is an important link in the early planning and test implementation process of the structural dynamic characteristic test. [0002] The related technologies for th...
