Embodiment Construction
[0035] Attached below Figure 1-6 The application is described in further detail.
[0036] refer to figure 1, the embodiment of the present application proposes a rocket body natural frequency test support platform, including a main body support unit and an auxiliary support unit supported at one end of the radial side of the rocket body 1; the main body support unit includes a main body support assembly 2 and an eversion Side 3, which is detachably connected to the main body support assembly 2 and fixed to the other end of the rocket body 1, so that the main body support unit can be indirectly supported on the other end of the radial side of the rocket body 1. While indirectly or directly supported by the main support unit and the auxiliary support unit on the radial side of the rocket body 1, the rocket body 1 can move slightly along its radial direction under the action of force. An end cover 4 is detachably connected to the side of the rocket body 1 near the auxiliary su...

The invention provides a rocket body inherent frequency test supporting platform, which relates to the technical field of rocket test auxiliary equipment and comprises a main body supporting unit and an auxiliary supporting unit which are respectively supported at two ends of the radial side of a rocket body and can allow the stressed rocket body to do axial or radial micro movement, the main body supporting unit comprises a main body supporting assembly and an outer flange which is detachably connected to the main body supporting assembly and fixed to one end of the rocket body, and an end cover which is of an opening structure along the axis of the rocket body is detachably connected to the end side, close to the auxiliary supporting unit, of the rocket body. The device has the effect that the problems that the test efficiency is low and potential safety hazards exist in an existing hoisting mode due to the fact that rocket bodies of different sizes cannot be tested through the same hoisting mode are solved.
Description
technical field [0001] The application relates to the technical field of rocket test auxiliary equipment, in particular to a support platform for natural frequency test of rocket body. Background technique [0002] With the development of domestic private rocket companies, the demand for rocket launches by private rocket companies has grown rapidly, and the frequency of rocket launches has become higher and higher. In the initial sample design stage, a full-scale rocket is used in the vibration test tower to conduct transverse and longitudinal vibration characteristics tests on the rocket, and the dynamic characteristic parameters such as the mode shape, natural vibration frequency and structural damping coefficient of the rocket body are measured, and the structure of the rocket body is determined. , power plant system, attitude control system and load calculation provide design basis. In the prior art, when testing the natural frequency of a rocket body with openings at b...
