AI Technical Summary

Problems solved by technology

During the vibration test, some current vibration tooling amplifies the vibration level of the tested product relative to the original vibration level, which cannot truly reflect the performance of the tested product, and even causes irreparable damage to the product, especially This kind of precision power transmission device, due to improper test equipment or methods, is more prone to invalid tests and direct scrapping of products

Abstract

The invention discloses a vibration test method of a precision power transmission device. A power transmission device under test is fixed in the middle of a vibration test bench by means of a vibration tool. During a vibration test, an assigned vibration requirement is transmitted to the precision power transmission device at a ratio of 1:1 through a control sensor and a monitoring sensor, and dynamic performance indices of the precision power transmission device under test are monitored in real time, i.e. through controlling the actual vibration level of an object under test, the real-time contact resistor fluctuation value of the object under test is monitored during the vibration process, and the signal transmission reliability of the precision power transmission device in a vibration environment is accurately reflected.

Description

technical field [0001] The invention relates to a vibration test method of a precision power transmission device, belonging to the technical field of vibration tests of precision electromechanical components. Background technique [0002] In the missile / rocket / aircraft inertial platform system, the precision power transmission device undertakes the important task of supplying power to internal devices and inertial instruments and transmitting signals. It can be called the "central nerve" of the inertial platform system and is a highly integrated, Representative of precision manufacturing and high precision signal transmission. With the development of inertial platform systems in the direction of high precision, high reliability, high integration, and long life, precision power transmission devices are required to have the ability to simultaneously transmit high power and small signals, redundancy, miniaturization, high and low temperature alternating environments, high With...
