The Excitation Vibration Test and Analysis in Cotton Precise Plastic Film Layering Sower
摘要
Abstract
A large number of field Cotton sundry to drill the larger vibration impact in southern xinjiang , reduce the row of kind of accuracy .To test the machine vibration characteristics under different operation speed , precise coated with 2 BMJ-8/2 mechanical cotton seeding machine for the test point , using vibration instrument measuring point , testing vibra-tion displacement under different operation speed , and frequency spectrum analysis was carried out on the test data .Re-sults show that the effect of seeding machine operation speed is 9.8 10.5km/h, mainly in low frequency vibration ampli-tude of 0 to 10 HZ frequency , are motivated by the vibration of the main clutter for the field winding , clod vibration , etc;Plastic film layering sower operation speed of 7.5~8km/h, the seeder vibration amplitude was decreased , can keep the optimal efficiency and working conditions for the optimal;Plastic film layering sower operation at low speed , small vi-bration amplitude , vibration frequency , between 0 to 50 hz and frequency close to the vibration of the diesel engine , the vibration motivation mainly comes from the tractor vibration power .关键词
