摘要：To study the influence of the random load on the V-lock chain ring for mining,the numerical simula-tion technology is used.The dynamic tension is obtained by using the dynamic model of the plough.The life and damage nephograms are obtained by using ANSYS Workbench.The analysis results show that the short fatigue life region of the V-lock chain ring for mining is mainly concentrated on the transition region between the medial straight edge and arc,and the fatigue damage of the link chain on the side of the motion direction of the plow head is larger than that on the other side.This link chain has strong anti-fatigue performance.
