Why is the spring chosen by CII smaller than one selected from the table?
Thread Content
For the 4 springs shown in the diagram, the numbers 13, 15, 14, and 15 were selected; the corresponding working loads are 9663, 15276, 12358, and 15483 respectively. However, when referring to the table for selecting variable spring load-displacement combinations based on working loads (JB/T 8130.2-1999), the numbers 14, 16, 15, and 16 are used instead. Why is this? Which one should I choose? Note: The subsequent values represent the installation load (with the actual installation load being 0), the spring stiffness in N/CM, the horizontal displacement, and the rate of change of the spring load during verification; all of these values are less than 25 percent
If you change to a different spring manufacturer, the results will be different.
In the software’s spring settings, by using a different spring table, the calculated results will also vary.
