The Study of Plastic Snap-fit Design and the Development of Snap-fit CAD Application Module

塑料卡扣设计研究及CAD应用模块开发

Therefore, the strength and reliability of the locking features play a very important role in the snap-fit connection.

因此，锁紧功能件的强度和可靠性在卡扣连接中起到十分重要的作用。

Locking feature as an important part of the snap-fit attachment bears the combined effects of insertion force and deflection force.

锁紧功能件作为卡扣的重要组成部分，承受着装配力和偏斜力的综合作用。

The maximal stress and strain of snap-fit of POS machine could be easily obtained by taking advantage of ANSYS and the process of assembly can dynamically displayed so as to be used to check up the rationality of the design of the snap-fit.

用ANSYS可方便地确定POS机卡扣的最大应力和应变，并可动态显示其装配过程，以检验卡扣设计的合理性。

Both the analytical result by ANSYS and the calculated result by the simplified formula were compared to show that the analysis of the complicated structure of snap-fit based on ANSYS was a better way.

再对基于ANSYS的分析结果与简化计算公式的计算结果进行比较，结果表明对复杂的卡扣结构采用ANSYS分析方法是合适的解决方案。
