Kinetic Model of the Shearer Operated by Outside Power

摘要

On the basis of analyzing traction property of anchor chain of the shearer operated by outside power, the kinetic model is simplified as spring-mass system with mass. And by adopting the method whose mass is gathered and contracted, this system may be discrelized as an approximate system with n degree of freedom. Then the kinetic mathematical model of the system is established, each multiple natural frequency and vibration model as well their variation regularities with the running position of the shearer are given.
