Load Spectrum Computer Simulate Of The Pick-shaped Of Coal Cutter's Drum

In accordance with the cutting-test of the pick-shaped tooth and knife-shaped of drum cutter on the same cutting depth and cutting speed, this paper studies the coal cutting forces big or small relation of the pick-shaped tooth and knife-shaped tooth by the lump coal test-bed<, As the same time, gets the cutting characteristic of the pick-shaped tooth ?Though the test of pick-shaped tooth0 this paper also sets up the different force mathematical model of pick-shaped tooth on basis of the character and imitates the force curve of single tooth with the rotating of drum, works out the average and stochastic load imitate program by studying the load of drunio In the program weave process adopts the program apply interface ?analyses and appraises the cutting force character of the drum cutting tooth under the different coal sea...
