Abstract: High performance round link chains are applied in many fields, such as mining, metallurgy, hoisting, shipping, etc. and accidents can easily happen under the condition of bad or complicated working conditions. This paper studies the dynamic analysis of the round link chain transmission process. The kinematics analysis is carried out first, and then the dynamic analysis is carried out after the force analysis of each component. By establishing the mathematical equation of the structural model of the round chains chain, the two static analysis models for the contact of the chain link are derived. Then, the collision process between the round link chains is simulated and analysed. Finally, fatigue fracture mechanism of round link chain and the propagation law of fatigue crack are studied, also, experiments verified that the round link chain satisfies the actual requirement in special needs such as mining.
