What is the max deflection of a spring?
The maximum deflection is the measure of how far the spring can travel before it suffers damage. The maximum spring compression is the maximum deflection specifically of compression springs.
How much load can a spring take?
The maximum load that a standard variable spring can support is 50,000 lbs. The maximum load that a standard constant spring can support is 90,000 lbs. A big ton spring support can be be used for loads greater than these standards.
What does deflection at load mean?
In engineering, deflection is the degree to which a structural element is displaced under a load (due to its deformation). The deflection distance of a member under a load can be calculated by integrating the function that mathematically describes the slope of the deflected shape of the member under that load.
What is the relationship between spring tension and deflection?
To calculate the amount of deflection you may achieve under a certain load, you may calculate it by dividing the required load by the spring rate. If this is an extension spring, you must subtract the initial tension from the load first.
How do you calculate spring load?
To calculate the working loads, you need to use the spring rate. Either you divide the load by the spring rate to calculate distance traveled, or you multiply the distance traveled by the spring rate to calculate the load. You can also calculate your required spring rate using working loads.
What is a normal spring rate?
Springs should typically be compressed 25-30% of the free length when supporting the weight of the vehicle. Drag race cars will normally use a lighter rate spring (about 30%) to promote weight transfer while a street car will use a firmer rate spring (about 25%).
What does deflection mean in Springs?
Spring deflection is how a spring responds when force is applied or released. For example, if a compression spring compresses one inch for every 200 pounds of load applied to it, its deflection rate is 200 lbs. The deflection limit definition for the load on a linear spring is the rate times the length of the spring.
