摘　　要：在考虑物料非线性作用力基础上建立含有物料结合系数的倾角振动输送机力学模型,采用解析法对该模型进行求解与分析。分析结果表明:当工作面有倾角时物料结合系数比工作面无倾角时小;物料结合系数与阻尼系数随着振幅的增大而减小,其中物料结合系数减小较快;物料结合系数随着转速的增加而减小。Mechanical model of vibration conveyer with inclination was built, and the model which was based on nonlinear force of material with material combination coefficient was solved and analyzed by analytical method. The results showed that material combination coefficient in inclined face is less than that without inclined face, and material combination coefficient decreased faster than damping coefficient when amplitude increased. Moreover, material combination coefficient is lower when rotational speed increased. The same kind of vibratory machines which were based on the analysis of results obtained better dynamic performance and has longer service life.
