摘要
本文利用最简单的二面楔子和复合楔子的受力分析，采用相似性方法，推导出计算土壤工作部件工作阻力的数学模型．这就有可能不经过耗资大的试验过程，利用简单的数学公式计算工作部件的土壤阻力，从而简化部件的研制过程，实现部件设计的优化，为科学地评价部件动力性能提供科学依据．
Applying stressed analysis of two-side wedge and complicated wedge,mathematical model of soil workpiece resistance was derivated by similarity method.It could calculate the resistance of workpiece with simple mathematical formula instead of experimental process which expended much fund,so it simpled the development processing of parts,optimized parts sign,provided scientific basis for evaluating parts dynamic performance
