Study on High-Strength Ring Chain Dynamic Characteristics Under Different Launch Parameters

The aim of this study is to investigate the mechanical characteristics of the high-strength ring chain under various launch parameters and the energy consumption caused by this. Particularly, the contact dynamics simulation was implemented in ABAQUS to study the launch characteristics impacted by different chain speeds different transportation loads, and the results were proved by experiments. The results show that stable stresses under different launch speeds are diverse, and the launch speed providing the optimal performance is 5.6 m/min; stable stresses under different loads are diverse, and in the overload-launch process, the normal force of the chain increases multi-fold so that the chain will be significantly damaged. The share of energy consumption by the friction of high-strength ring chains under idle/no-load operation conditions is 23.8% of the total value. With the rise in loads, the total consumption grows linearly. As a consequence, the results obtained are quite instrumental in the research of ring chain launch characteristics, prediction of chain operating life, and the efficiency improvement of electromotors.
