摘　　要：To fulfill the operational demands of deep-sea tracked mining vehicles traversing soft seabed substrates,an evaluation of the characteristics of these substrates was conducted,drawing a comparison with the land swamp black soil found in the buffalo's habitat.Employing the principles of biomimicry,two distinct types of bionic grouser were devised,replicating the configuration of the buffalo's hooves in both the horizontal and vertical planes.Utilizing self-constructed testing platforms,exhaustive examinations of the reinforcement efficacy of these bionic track grousers were undertaken,spanning from single-grouser to multi-grouser configurations and encompassing the entire track assembly.The findings unequivocally demonstrate a pronounced and consistent enhancement in traction force for both types of bionic grousers.Notably,the W-shaped bionic grouser,mimicking the horizontal contour of the buffalo's hoof,exhibits the most substantial increase in traction force.The maximum enhancement in traction force for individual bionic grouser exceeds 30%,while the overall track achieves an increase of over 19%.This research provides a valuable reference and establishes a foundational framework for the design of equipment tailored for the locomotion of deep-sea tracked mining vehicles across soft substrates.
