Abstract: In response to the high labor intensity of manual operations in coal mines, an exoskeleton was developed to assist miners in transporting and carrying heavy tools or materials in underground mining workings. The structural design and functions of each part of the exoskeleton were introduced. By using finite element analysis technology, the equivalent stress and displacement distribution law of the core components of waist and leg exoskeleton under working conditions were obtained. Based on this, combined with topology optimization technology and technological characteristics of manufacturing process, the optimal structural scheme of the components was obtained. Finally, a lightweight design with a total weight of 8.3 kg (23.1% decreasing of weight compared to the original design) was developed for the waist and leg exoskeleton, providing a solid foundation for the application of exoskeletons in conditions of coal mine.
