Springs in Parallel

Definition of Parallel Springs

 

When a group of springs work together under one force or load.

 

When springs work in parallel, you have more force to withstand your working loads. Ninety nine percent of the time the springs will be identical which is why we’ve provided you with the following formulas to calculate the amount of force (equivalent rate) you’re generating when placing a load on these springs.

 

Rate With Identical Springs Example

 

If you have 4 identical compression springs, and need to have an equivalent spring rate of 40 pounds per inch (lbs/in), you divide the equivalent rate by the number of springs. The result of this equation is the constant spring rate/force that each spring needs to have.

 

Formula for Parallel Springs Rate

Single Spring Rate = Equivalent Rate ÷ Number of Springs

Parallel Springs Rate Calculation

Single Spring Rate = 40 lbs/in ÷ 4 springs
Single Spring Rate = 10 lbs/in

Load With Identical Springs Example

 

To know how much load you will achieve per spring, you will also need to divide the equivalent load by the number of springs. If you’re applying a force of 20 pounds and divide it by 4 springs, the load each spring will be carrying is 5 pounds.

 

Equation to Calculate Load Per Spring

Load p/ Spring = Equivalent Load ÷ Number of Springs

Parallel Springs Load Calculation

Load p/ Spring = 20 lbs ÷ 4 springs
Load p/Spring = 5 lbs
