How do you calculate combined spring rate?
(Identical Spring Rates) You have two identical springs with a spring rate of 30 lbf/in (pounds of force per inch). To calculate the rate these two provide together, simply multiply the rate by 1/2 (0.5).
What should my spring rate be?
The softer rate will generate a smoother ride while the stiffer spring will result in a firmer ride. You need to consider these options when you are selecting the proper spring rate for your application. Springs should typically be compressed 25-30% of the free length when supporting the weight of the vehicle.
What is a good spring rate for coilovers?
With a typical street car, you’re looking for the weight of the vehicle to compress the springs 25- to 30-percent. For drag cars, you will typically want between 30- and 35-percent of the spring to compress.
What is a dual rate spring?
Dual-rate: a spring combination that utilizes two springs in a series to achieve a softer initial rate. Once the Secondary Spring goes to block or the slider hits the stop ring (called Transition Point) the load deflection characteristic changes solely to the rate of the Primary Spring.
What is the spring constant of two springs in series?
5 N/m
Using the same springs as the first example, when two 10-N/m spring scales are combined in series, the resultant spring constant for the two-spring system is 5 N/m. The resultant spring constant is half the value of the original, single spring constant.
How do you add spring rate in series?
To calculate the rate being exerted when using more than one spring, you simply add them together. If the springs have different spring rates, you must add each rate individually. However, if the springs are identical (thus having the same spring rate), you multiply this value by the number of springs working together.
What is a good spring rate for daily driving?
You should run stiffer springs in the rear. 8/10 (F/R) for daily driving should be nice. not too harsh, not too soft in my opinion. may be just a little bouncy if you have bad roads.
Are dual rate springs better?
These springs are much more sophisticated than a typical linear spring. A dual-rate spring will provide a much better rate of transition when the spring is under compression and hard load. It’s important to note that this type of progressive spring is more oriented towards high-performance driving.
What happens when two springs are connected in series?
When the same springs are connected in series, as shown in the diagram below, this is referred to as a series connection. On spring 2, a constant force F is applied. As a result, the springs are elongated, and the total extension of the combination equals the sum of each spring’s elongation.
What’s the difference between the Discovery I and Discovery II?
Both the Discovery I and Discovery II share a similar shape, but Land Rover really modernized the Discovery II. The Discovery II was the first SUV to use airbag suspension and an optional cornering enhancement system known as ACE.
What happens when you put two springs in a series?
(The compliance of its spring constant.) When putting two springs in their equilibrium positions in series attached at the end to a block and then displacing it from that equilibrium, each of the springs will experience corresponding displacements x 1 and x 2 for a total displacement of x 1 + x 2.
What kind of sway bar does Discovery 2 have?
The Discovery II also had an optional sway bar system called ACE, also known as “Active Cornering Enhancement.” This system used a hydraulic pump and hydraulic rams to make the Discovery II corner extremely flat. This system can also completely disengage at low speed to increase articulation.
What kind of engine does a Land Rover Discovery have?
Land Rover, however, gave the Discovery I a much lower price point. Early models in the US came equipped with a 3.9-liter V8, but Land Rover upgraded later models to the 4.0-liter V8. The Discovery I was the vehicle used in the “Camel Trophy” which proved its reliability in all conditions.
