Paper Title:
Study on Noise Control of Fan with Air Suction
  Abstract

Fan is a pneumatic device in the 4ZTL-1800 combine harvester threshing prior to cutting. Based on the prophase search result that fan noise is highest when fan rotates at 1200r/min, in order to decrease noise of it, sigle-microperferated-panel muffler, double-microperferated-panel muffler and interposition muffler were designed and tested. The results show that double-microperferated-panel muffler is best and sound power level of fan is decreased 11dB, and that interposition muffler is better, and that sigle-microperferated-panel muffler is worst to descrease fan noise. Through contrast on transmission power loss of different mufflers, cone-shaped double-microperferated-panel muffler is verified to be best for noise control of fan.
