中文摘要：

当槽轮的槽数一定时，普通槽轮机构的运动系数是定值。以椭圆齿轮机构作为槽轮的驱动曲柄，利用椭圆齿轮机构的变传动比特性，可以改变槽轮机构的运动特性。文中分析了机构运动系数的变化规律，给出了最大运动系数和最小运动系数的计算方法，提出了按照运动系数进行椭圆齿轮槽轮组合机构综合的方法，以及槽轮中位具有一段匀速运动特性的组合槽轮机构参数。

英文摘要：

Based on comparative analysis, the lowest annual comprehensive cost was taken as the objective function of optimization design. The function relationship between the annual comprehensive cost and the structural parameters of the watercooled surface cooler was given under restrained conditions, that is the mathematical model of the surface cooler optimization design, providing certain referential data for achieving reasonable matching between the surface cooler and relevant parts.
