Abstract: In order to study the trajectory of the inner cone of the vibrating slow shear crusher, a six-degree-of-freedom inner cone dynamic model was established through Lagrangian equations and MATLAB was used to solve the inner cone dynamic response.The ADAMS simulation software was used to perform the inner cone under no-load cone dynamic response simulation analysis, coupling of EDEM and ADAMS was used to analyze the inner cone dynamic response under load.The results show that the movement of inner cone of the vibrating slow shear crusher is mainly the circular vibration on the horizontal plane.The displacement range in X and Y directions under no-load conditions is from-0.4 mm to 0.4 mm, and the overall amplitude is 0.8 mm.The displacement range in X and Y directions under load is from-0.3 mm to 0.3 mm, and the overall amplitude is 0.6 mm.The amplitude under load is smaller than that under no load.

Keywords: vibrating slow shear; crusher; multiple freedom degrees; vibrating circular motion；dynamic analysis
