通过试验，研究了自同步振动磨机内物料运动形式，考虑了物料区间性非线性作用力，建立了物料非线性作用力自同步振动磨机的振动方程．用非线性理论中的等效线性化法求出振动方程的一次近似解及物料的结合系数与阻力系数 Through the experiment, the movement form of the material in the self-synchronous vibration mill was studied, the nonlinear force of the material was taken into account, and the vibration equation of self-synchronous vibration mill with material nonlinear force was established. Using the equivalent linearization method in nonlinear theory, the first-order approximate solution of the vibration equation and the combination coefficient and drag coefficient
