The Measurement of Dynamic Stress for The Top-Cutter Machine of Cotton

In this paper, we used the dynamic strain measurement method to measure the top-cutter machine of cotton’s stress under its working state. With sorting out data and analyzing it, we obtained the stress condition of the framing and the working parts. And the measurement result could be used to analyze the axle’s fatigue strength and check whether it was safe or not. It provided integrant basis for the further design of the machine.
