| 摘 要： | 为研究履齿高度对集矿机在多金属结核矿区稀软底质上的牵引性能的影响,并确定履齿高度,以优化集矿机的行走机构。该文基于稀软底质的剪切位移和应力模型,构建了单履带板、齿与稀软底质的驱动力模型和集矿机的附着力模型,研究了履齿高度参数对集矿机在稀软底质上的牵引性能的影响。结果表明,履齿高度能提高集矿机在稀软底质上的牵引性能:集矿机在稀软底上产生的驱动力随履齿高度增加而快速增加;附着力在齿高小于15cm时随齿高增加快速增加,齿高大于15cm后趋缓。集矿机的齿高应不大于15cm。 |

| Abstract: | In order to analysis the influence of height of seabed of track shoe tracked vehicle on traction performance, the shearing strength-shearing displacement model of deep-sea soft sediments were obtained by shearing testing of simulated sediments in testing pool, and then the traction force model of the sediments and the adesion force model of the tracked seabed vehicle were founded. The influence of the height of track shoe on the traction performance of the seabed tracked vehicle was researched by traction force model and adesion force model. According to the research, the traction performance of the vehicle increases with the height of the track shoe on deep-sea soft sediments, and the traction force of the vehicle on sediments increases quickly with the height of track shoe. The adesion force increases quickly when the height of track shoe is less than 15 cm and then increases slowly when it is more than 15 cm. The height of track shoe should be not more than 15 cm. |
| Keywords: | construction equipment adhesion drives seabed tracked vehicle deep-sea soft sediments traction performance height of track shoe |
