Problems solved by technology

However, this test device is not suitable for electromagnets with the characteristics of high speed, high precision, small stroke (generally less than 2mm), light and small size, etc., and this type of electromagnet performance test requires a static performance test that is convenient to adjust different strokes device, and the need for a dynamic performance test device that is convenient to adjust different preloads
[0005] The electromagnets required by solid attitude and orbit control engines generally have the characteristics of high speed, high precision, small stroke, light and small size, etc., but for this type of electromagnet, there is still a lack of simple and effective static and dynamic performance testing methods. Restricted the electromagnet research and development process

Abstract

The invention relates to an electromagnet testing device, which can realize electromagnet static performance and dynamic performance test. A static performance device comprises a precision displacement adjusting device, an orientating and locking device, a force test and strutting device, an electromagnet fixing device and a displacement test device, and can obtain electromagnet static characteristics in different strokes. Based on the electromagnet static device performance device, a dynamic performance test device is partially improved by providing a pretightening force loading device. The pretightening force loading device comprises a support bar, a spring, a loading rod and a third straight bearing, wherein the third straight bearing provides straight-line guidance for the loading rod; the loading rod can move left and right in the support bar; the spring performs compression or stretch under the relative displacement between the support bar and the loading rod, and generates required pretightening force, thereby obtaining electromagnet dynamic characteristics under different pretightening force.

Description

technical field [0001] The invention relates to an electromagnet testing device, in particular to a static and dynamic performance testing device for electromagnets with the characteristics of high speed, high precision, small stroke (generally less than 2mm), light and small size, and the like. Background technique [0002] With the development of digital integrated circuit technology in modern society and the needs of aerospace, electronics, machinery manufacturing and other fields, high-speed electromagnets are more and more widely used. The electromagnet is a multidisciplinary product of electricity, magnetism and mechanics. It has strong integration and has become the core technology of solid attitude and orbit control engines. The advantages and disadvantages of its static performance and dynamic performance have a great impact on the overall system scheme of the engine. Subversive problems may occur in severe cases, so it is very necessary to test the static and dynam...
