滑撬 meaning in Chinese

sled

The thesis had done the theories analysis in detail and built the relevant mathematics models aiming at the mechanics characteristic about the lodging of stalk , the elastic and plastic deform of stalk under the action of the transverse loads , the mechanics condition which causes stalk pushed , the relation between the speed of unit and the surface radius of ski , the relevant location between the thickness of the compressed stalk and action location of load , the relevant location between the mating device and plough , the coefficient of overturning soil under the thickness of the compressed stalk and so on . in addition , the computer aided analysis and simulating experiments in field were acted by choice
本文对秸秆自倒伏力学特性；横向载荷作用下的茎秆弹塑性变形与秸秆被推倒的力学条件；机组作业速度与滑撬曲面半径的关系；秸秆压实厚度与加载作用点的相对位置；配套装置与犁体相对位置；秸秆压实厚度下的翻垡系数等，进行了较详细的理论分析并建立了相关数学模型。在此基础上，本项研究还选择性地进行了计算机辅助分析和田间模拟试验。
