Types of Spring Classification based on the load force applied, we have the: Tension or extension spring Compression spring Torsion spring Constant spring Variable spring and, Variable stiffness spring Classification based on their shapes: Flat spring Machined spring Serpentine spring and, Garter spring Classification based on how common they are: Cantilever spring Coil or helical spring Volute spring Hairspring or balance spring Leaf spring and, V-spring Other classifications include: Belleville spring Constant-force spring Gas spring Ideal spring Mainspring Wave spring and so on.

F is the resulting force vector. Factors That Affects Spring Rate There are three major factors that affects spring rate: Wire diameter: when the wire diameter increases, the spring constant increases too. A thicker wire will make the spring constant become stronger and even difficult to deflect. Spring diameter: increase in the spring diameter will lead to decrease in the spring rate.

Number of coils in the spring: the higher the number of coils, the lower the spring constant. Theory of Springs In classical physics, a spring can be viewed as a gadget that stores expected vitality, explicitly flexible possible vitality, by stressing the bonds between the molecules of a versatile material.

Natural Gas Industry The processing and refining of Natural Gas into a marketable products, by separating gas into pipeline-quality natural gas and a stream of mixed natural gas liquids and the transportation of natural gas to through a series of reciprocating compressor stations and pipes, and from there to end users. This spring rate represents an increase of 21 percent over the stock spring rate. With these figures, the Lotus owner can make an informed decision regarding how many coils he needs to cut from the spring before he does the actual cutting, thereby avoiding any unpleasant surprises.

As has been outlined here, a great deal of information can be derived from the simple equation for the spring rate of a coil spring. If the spring constant equation is used as a reference when making decisions regarding coil spring modification, specification, or substitution, the likelihood of a successful decision will be considerably enhanced.

So get out those pocket calculators and start modifying your suspension the logical, scientific way. Your competitors may not notice your improved mathematical abilities, but they will be sure to notice your n quicker times. Like what you're reading? We rely on your financial support. Understanding anti-roll bars. Understanding alignments. Love it Good stuff from GRM Back in '88 I put all this in Excel. From these plus the items in the article, the current spring's stiffness and the weight on that corner are calculated.

When the difference between the desired and calculated ride heights goes negative, it stops and reports the most recent iteration. The "incremental steps for reference" are just there as a sanity check that the calculated number of coils to cut are reasonable.

Interesting "spring steel" and regular steel act the same way. Had no idea. You'll need to log in to post. Log in. Login Digital Edition Buy a Subscription. This al geometry may in turn induce undesirable handling characteristic Next, refer back to the formula and notice the effect of the n of coils N. Restating the spring constant equation: Since d, G and D will remain constant, these terms can be ignored.

David S. The outside diameter can then be calculated by measuring the largest dimension on the outside of the last coil. The inside diameter can be calculated by placing the teeth of the caliper on the inside diameter. The free length is measured by placing the calipers on the entire length of an uncompressed spring. Start counting all the coils from one end beside where the wire has been cut while ensuring that all portions of the coil are counted.

All the dimensions having been determined means you can proceed to calculate the spring load using a spring calculator or employing the services of an expert. These are the important details to understand when it comes to spring load and its relation to spring rate.

The formula to calculate each has been provided and even how to theoretically determine spring load for a torsion spring, helical spring, and other spring types.
