Harmonic Response Analysis On Cutting Part of Shearer Physical Simulation System Paper Title
Coal-rock interface recognition system mainly means collecting various response signals available from multi-sensors equipped in shearer and further analyzing and those response signals to see if it is cutting coal or rock. For this purpose, the shearer equips total five types of various distinguishing sensors to pick up these signals. Both the optimized configuration of sensors measuring points and the choices of the sensors properties are the key factors to correctly and completely collecting the manifold dynamic characteristic signals of cutting part of physical simulation system. Therefore, it is important and necessary to carry out the harmonic response dynamics analysis of shearer cutting part. The vibration characteristics based on frequency response is analyzed. The study not only optimizes the disposition of the vibration sensor for the maximum output amplitude signals, but also identifies the frequency range of the vibration sensor, so that it not only satisfies the condition for undistorted measurements, but also avoids that the sensors are interfered due to resonance.
