Problems solved by technology

The release method is a rough method, which is not suitable for high-precision tests; in the method of cutting the suspension line, the center of gravity of the test object must pass through the suspension line. If the test requires that the center of gravity of the test object does not pass through the suspension line, then it must It is required to add several suspension wires, so that there is no guarantee that these wires will be broken at the same time at the moment of thread cutting; the accuracy of the mechanical release method is high, but this method requires special mechanical equipment, and this method generally It is designed for some special tests, not universal and flexible

Abstract

The invention relates to the technical field of physical mechanics tests, specifically relating to the free release process of the tests, and relates to a high-precision free release control apparatus based on an electromagnet, and a control method of the same. The high-precision free release control apparatus based on an electromagnet includes an electromagnet, a clamping piece connecting with the electromagnet, an attitude controller, an altitude controller, a D.C. regulated power supply and a switching device, wherein the attitude controller can be designed in different attitudes according to different test requirements; the altitude controller is connected with the attitude controller; and the D.C. regulated power supply is connected with the electromagnet. The high-precision free release control apparatus based on an electromagnet, and the control method of the same have the advantages of flexibility being adaptive to different test conditions, high precision in assembling and changing components, simplicity and stability.

Description

technical field [0001] The invention relates to the technical field of physical and mechanical tests, more specifically to the free release process of such tests, and to an electromagnet-based high-precision free release control instrument and a control method thereof. Background technique [0002] In physical and mechanical experiments, the problem of limiting the test object is often encountered. In particular, for tests such as free fall, free release, and free fall, the test object is required to be released from a fixed height and a fixed initial state, and even some tests have very strict requirements for this free release process, such as requiring the release process No interference, good repeatability of multiple tests, high stability, etc. The common release methods include the release method of letting go, the method of cutting the suspension line, and the method of mechanical release. The release method is a rough method, which is not suitable for high-precisio...
