How is spring rate related to load on Spring?
WHAT IS SPRING RATE? Spring rate refers to the amount of weight that is needed to compress a spring one inch. If the rate of the spring is linear, its rate is not affected by the load that is put on the spring. For example, say you have a 200 lb. per inch spring – it will compress 1” when a 200 lb. load is placed onto the spring.
Which is the unit of measurement for spring rate?
The units of measurement of rate in the English System are, lbf/in (pounds of force per inch) or N/mm (newtons per millimeter) in the Metric System. Spring rate is the most important part of your compression or extension spring design, but it is also the most complicated spring calculation.
How can I find out what spring I Need?
You can find the spring based on the maximum load or the maximum deflection. When you find the spring that meets your load and travel requirements, you can then check whether the spring rate meets your working loads. Furthermore, you can check pricing at different quantities by clicking on the Quick View icon.
What kind of springs are open wound linear?
Compression springs are also known as coil springs. They are open wound linear springs because they have the same amount of pitch between each one of the coils. Learn about their dimensions, specifications, and how they work. Compression Spring Deflection Calculation.
What do you need to know about spring rate?
Spring Rate Calculator. Definition: Spring rate, also known as spring constant, is the constant amount of force or spring rate of force it takes an extension or compression spring to travel an inch of distance or, in the metric system of measurement, a millimeter of distance.
When to use spring rate calculator for coil over?
Below are approximate spring rates for your coil-over application. This calculator will only give approximations depending on the accuracy of your information. Use at your own discretion. Recommended spring rate to optimize ride quality. Is best used for crusing, day to day use, and long distance driving.
What is sprung weight in spring rate calculator?
Sprung weight = Corner weight – Unsprung weight. It is the weight supported by the spring and is the only weight used in calculating spring rates. The “motion ratio” is the mechanical advantage (lever ratio) that the wheel has over the spring in compressing it.
How to calculate spring rate on ball joint?
Dimension B – Measure the distance from the control arm pivot point on the subframe to the centerline of the ball joint. Using a protractor or similar measuring device, measure the angle of the centerline of the spring or “coil-over assembly” from the horizontal of the control arm (or axle if calculating the rear).
