关于平行弹簧组等效劲度系数的讨论

在通常情况下,针对多个平行弹簧等效劲度系数的研究过程中,存在这样的假设:这些平行弹簧同时被压缩或伸长的量要相等。但是在实际中,更多的情况是:在同时间内,每个平行弹簧被压缩或伸长的长度各有不同。我们以劲度系数不相同的两个平行弹簧为例,将平行弹簧的一端固定,而对另一端压缩,每个弹簧被压缩的量不一致。在这种情况下,得到平行弹簧组的等效劲度系数。

Discussing on the Equivalent Stiffness Coefficient of Parallel Spring Groups

In the normal condition,there is an assumption in the research process of equivalent stiffness coefficient of many parallel springs:the amount of compression or elongation of these parallel springs at the same time must be equal.In practice,however,the more situations are that the amount of compression or elongation of every parallel spring at the same time is different.This article takes two parallel springs with different stiffness coefficient as examples:an end of parallel spring is fixed,the other end is compressed,and the amount of compression of every spring is different.In such circumstances,we can get equivalent stiffness coefficient of parallel spring groups.
