The invention relates to the technical field of structure dynamic characteristic tests, in particular to a fairing combining method for a fairing in a vibration tower. The fairing combining method includes the following steps that firstly, a first half fairing body is lifted into the vibration tower so that the inner wall of the first half fairing body can be close to the outer wall of a simulation airship in butt joint with a secondary rocket body; secondly, the first half fairing body is rotated around the simulation airship so that the first half fairing body can enter the installation position, and the opposite combining face of the first half fairing body is located on a fairing combining operation face; thirdly, the first half fairing body is connected with the secondary rocket body; fourthly, a second half fairing body provided with a fairing fixture is installed to the installation position according to the first step, the second step and the third step, and the opposite combining face of the second half fairing body can be opposite to the opposite combining face of the first half fairing body; and fifthly, the first half fairing body and the second half fairing body are combined. According to the fairing combining method, the problems that the due to the fact the movable space in the vibration tower is limited, interference of the tower entering space of the fairing with the fixture exists, and the operation difficulty of fairing combining of the fairing without the fixture is high are solved.
Description
technical field [0001] The invention relates to the technical field of structural dynamic characteristic testing, in particular to a method for closing a fairing in a vibrating tower. Background technique [0002] At present, 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 It can control the important design parameters of the stable system, and 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 product state is a decisive factor to determine the structural dynamic characteristic parameters. Therefore, how to ensure the state of the test product at the test site safely, efficiently...
