摘　　要：为满足农机市场对船式拖拉机的迫切需求,设计了新型船式拖拉机的关键部位之一换轮机构。在基于TRIZ理论的基础上,根据系统进化法则和系统矛盾对立消除法则设计的换轮机构,采用PRO/E进行建模,利用ANSYS分析齿轮应力大小及分布并计算输出轴的低阶模态,满足基本的设计要求。To meet the urgent demand of agricultural machinery market to boat-type tractors,a intelligently amphibious boat-type tractor is designed. The structure of change-wheel mechanism is one of the key parts. According to TRIZ theory and eliminating law of system contradictory opposites,the paper designed the change-wheel mechanism,established its model by using PRO / E,analyzed the value and distribution of gear stress by ANSYS,calculated the output shaft＇s low-order modes,and which could meet the basic design requirements.
