柠条平茬圆锯片的结构参数对圆锯片耐磨性能有着显著的影响，合理的优化结构参数会使圆锯片的耐磨性能极大的提升。为延长柠条平茬圆锯片的使用寿命，通过试验测量，并对测量结果进行理论分析，获得柠条和65Mn圆锯片的物理参数和接触参数，然后采用仿真正交试验法，结合锯片仿真模型的仿真结果，对齿数、齿厚、前角、后角，共4种主要的圆锯片结构参数进行分析，得到其对锯切过程中最大磨损量的影响。利用单因素仿真试验得到各个因素的影响曲线，以得到各因素的影响趋势。利用多因素正交仿真试验，以耐磨为目标，通过响应面分析和所构建的预测模型对上述的4个锯片参数进行优选和分析，结果表明，最优的参数组合是齿数100，齿厚2 mm，前角21°，后角21°，所得最大磨损量为8.249 96 μm，符合实际需求，可为分析柠条平茬技术和优化柠条平茬机构提供参考。

The structural parameters of circular saw blades have significant influence on the wear resistance of circular saw blades. Reasonable optimization of structural parameters will greatly improve the wear resistance of circular saw blades. In order to prolong the service life of Caragana flat stubble-saw blades, the physical parameters and contact parameters of Caragana and 65Mn circular saw blades were obtained through experimental measurement and theoretical analysis of the measurement results. Then, four main structural parameters of circular saw blades, including tooth number, tooth thickness, front angle and back angle, were analyzed by using the simulation orthogonal test method combined with the simulation results of the saw blade simulation model. Its influence on the maximum wear in the sawing process was obtained. The influence curve of each factor was obtained by single factor simulation test, and the influence trend of each factor was obtained. The four saw blade parameters were optimized and analyzed by response surface analysis and prediction model. The results show that the optimal parameter combination is tooth number 100, tooth thickness 2 mm, front angle 21°, back angle 21°, and the maximum wear amount is 8.249 96 μm, which meets the actual demand. It can provide reference for analyzing the cropping technique and optimizing the mechanism of Caragana.
