工程机械非完全对称四支腿反力简易计算方法

A Simple Calculation Method of Nonfull Symmetry Four Outriggers Reaction for Construction Machinery

基于变形设计中小型工程机械支腿反力的求解问题，给出了非完全对称支腿支反力计算的简化数学模型，用此数学模型对模拟试验样车进行了计算。计算结果与模拟试验结果对比表明本简化数学模型是正确、可行的。在此数学模型的基础上对臂架全回转过程中4支点受力，3支点受力进行了分析。

A simplified mathematical model for solving construction machinery outriggers reaction calculation problems is developed. Calculation on a simulatlon construction machinery are carried out using that model, the results of comparing experiments with calculation showed that the simplified mathematical model is correct and feasible. Based on the model, analyses of Four and three outriggers reaction during turning round of arm are put into practice.
