本文在研究履带板推进力形成机理基础上,将履带板推进力分为两部分,其一为由土壤内聚力及土壤对虚带板的外附力所产生的推进力;其二为由土壤内摩擦力及土壤对履带板的外摩擦力所产生的推进力。依据模型试验基本理论,为了避免模型畸变,推导出用两种模型履带板试验预测原型履带板推进力的方程式及试验方法。
In this paper, based on the study of the formation mechanism of track plate propulsion, the track plate propulsion force is divided into two parts. One is the propulsive force generated by the soil cohesion and the external force of the soil on the virtual belt plate; the other is from the soil. Friction force and the propulsive force of the soil on the external friction of the track shoe. According to the basic theory of model test, in order to avoid the distortion of the model, an equation and a test method for predicting the propulsive force of the prototype track shoe using two types of track shoe experiments were derived.
