Embodiment Construction

[0026] The technical solutions of the present invention will be described in detail below in conjunction with specific embodiments.

[0027] Such as figure 1 and figure 2 As shown in the present invention, a vibration loading combination device for a steering gear compartment of the present invention includes: vibration tooling and 4 sets of elastic rod combination devices;

[0028] (1) The vibration tooling is a square aluminum alloy plate. The steering gear cabin is installed on the vibration tooling through screws, and then the vibration tooling is installed on the vibration table through screws, so as to apply vibration conditions to the steering gear cabin and conduct vibration tests on the steering gear cabin;

[0029] (2) The steering gear cabin is a part of the spacecraft, and its shape is cylindrical. The four steering gear shafts are evenly distributed on the side of the steering gear cabin at 90° intervals. The rotation of the steering gear shaft drives the deflec...

Abstract

The invention relates to a vibration and loading combined device of a steering engine room, and belongs to the technical field of spacecraft controllers. The combined device is capable of control surface loading and vibration clamping of a spacecraft. The device is composed of a vibration tool and a torsional moment loading tool. The vibration tool as a clamp can fix the steering engine room to avibration table by switching. Four elastic rod assemblies are mounted on the vibration tool, and elastic torsional moment loads are applied to four steering engines in a stern room simultaneously viatorsinoal deformation of elastic rods. The vibration and loading combined device is characterized by being multifunctional, low in cost, easy to dismount, simple in structure, smooth in load output, consistent in elastic coefficients, and the like.

Description

technical field [0001] The invention belongs to the technical field of spacecraft control devices, and in particular relates to a steering gear cabin vibration loading combination device. Background technique [0002] The development progress of modern small and medium-sized spacecraft is accelerating, and the requirements for low-cost and miniaturization are constantly increasing. The traditional steering gear tooling has a wide variety and single function, which has brought many problems such as difficult control of the development cycle, difficulty in reducing costs, and frequent disassembly of products. The use of combined tooling can improve design efficiency, reduce tooling development costs, and has the advantage of being able to carry out multiple test items after one clamping. The loading device of the steering gear needs to provide accurate and stable linear load in the case of fast movement of the steering gear in a limited space. The elastic rod loading method is...
