The Principle and Applicalion of an Mechanical Micro-Power Measuring Instrument

This paper discusses a methed to measure the parameters of mechanical micropowers and introduces the measuring instrument. The instrument includes a strain sensor to measure micro-forces and a mechanism to translate a moment of force into a force. The analyses and calculations of the design and test of the sensor, and the test results are given. A velocity simulation was specially designed to suit the characteristics of the measured parameters.The principle and construction of the instrument are demonstrated, as well as its practical application. Actual test results of some precision micro-mechanisms are given.
