2、，考虑其独立性和通用性和通用性。独立性是可独立实现某一功能，比如支撑、连接、变速、润滑。独立性是可独立实现某一功能，比如支撑、连接、变速、润滑等等,通用性是通用性是具有相同的数理模型，具有相同的数理模型，能用相同的函数或参数表达。能用相同的函数或参数表达。Classified by the functionality of product components,considering their independence and universality.Independence refers to the ability to independently achieve a certain

3、function,such as support,connection,variable speed,lubrication,etc.Universality refers to having the same mathematical model and being able to be expressed using the same functions.模块的划分 Classification of modulesf(D,R,N)f(C,U)f(D,N)对于每一个独立的模块需要研究其物理性能和几何尺寸之间的相互关系，以快速评估其是否能满足功能需求。以行星轮系模块为例，推导其数理关系、参数

4、定义及函数表达：For each independent module,it is necessary to study the interrelationships between its physical performance and geometric dimensions to quickly evaluate whether it can meet functional requirements.Taking the planetary gear train module as an example for mathematical model derivation:接触应力：接触
