针对榫头的设计要求,介绍了榫头的设计方法和过程.以榫头重量最轻和满足静强度约束为基点,确定榫头的控制参数,实现了人机交互的榫头参数化设计.

英文摘要：

Aiming at the design requirement on serration, the method and process of the serration design are proposed. The control parameters of serration are defined based on the least weight and meeting the static strength constraint, and the man-computer interactive parameterized design of serration is realized.
