微型履带拖拉机牵引附着性能研究——基于正交试验

Research of the Micro-crawler Tractor Adhesion Performance——Based on Orthogonal Experiment

通过设计正交试验,研究某微型履带拖拉机的履带结构参数—履带板宽度b、履带支承段长度L0以及履刺高度h对整机牵引附着性能的影响;通过试验数据处理,量化分析各个参数对于附着力的贡献,获得试验范围内这3个参数的最优组合。试验结果表明,履刺对于附着力的影响最大,履刺的存在能够提高附着力达26.64%;在试验范围获得的各参数的最优组合为b=125 mm,L0=1 020 mm,h=28 mm。此结果为该类履带车辆履带的设计和选用提供了理论依据。

In order to find out the effects caused by changing the crawler structural parameter which includes Track Shoe Width（b）,Caterpillar Supporting Section Length（L0） and Track Shoe Grouser（h） on the adhesion performance,the essay designs and conducts an orthogonal experiment.Through analysis the dates quantificational,find out the optimal combination.The result indicates that Track Shoe Grouser plays a crucial role in improving adhesion performance.Because of its exits the adhesion performance enhanced by 26.64%,the optimal combination in trial stretch is：b=125mm,L0=1020mm,h=28mm.Therefore theoretical basis is provided for caterpillar tread design of this kind of tractor.
