Jan 22, 2004 · Coilover Spring Rate & Force Modeling Calculator It's what it says it is: an Excel spreadsheet tool to allow you to model the result from combining different springs on a coilover shock. Apr 8, 2023 · Calculating spring rates for a dual rate coilover involves determining the stiffness of the two springs used in the coilover. ) See Figures 1-3 below. It took a few more steps than using the standard compression spring software, but we're just getting started! Making a dual rate spring. where: B B is the bottom spring rate in N/m. Determine the unsprung weight of the vehicle: This includes Jan 21, 2016 · Stacked Spring “Combined Rates” Chart. Spring Rate Calculator (Helical Compression) This tool is designed for reference purposes only in order to help determine an approximate rate of existing unmarked helical round wire compression coil springs. 21 Jan January 21, 2016. Spring Rate is defined as the amount of force required to move the spring a given distance, which means a 100lb/in spring will travel 1 inch for every 100lb of force exerted on the spring. Now, we can calculate the spring rate (k) using the following formula: k = Gd^4 ÷ (8D^3 * n) k: Spring Rate; G: Shear Modulus; d: Wire Diameter; D: Mean Diameter; n : Number of Active Coils; This formula tells us how the spring's physical dimensions and material properties combine to determine its stiffness. 1 day ago · The Dual Spring Rate Calculator finds the combined spring rate when two springs work together in series. The Dual Rate UHT Spring combines a relatively low initial spring rate, designed to absorb minor undulations and increase grip with a precise transition point and transition range to a secondary higher spring rate to improve roll No problem. If the top spring rate is 300 N/m and the bottom spring rate is 500 N/m, the dual spring rate is calculated as: Learn how to stack suspension springs to create a dual rate system, reducing the overall spring rate and distributing deflection. Springs loose; Dual rate nuts high on the body, spring slider not touching dual rate nuts; Tighten the preload nut down while gently rattling the springs, when they stop rattling that is Zero Preload. which will likely be a 100 lb. In this short text, we will cover the following: What is the spring rate or spring stiffness?; How to calculate spring rate; Different ways to find the spring rate; and; More about this property of springs. There are many variables which are not represented in in these calculations, therefore results are estimates and may vary. 62. Determine the total weight of the vehicle: This includes the weight of the vehicle, passengers, and any cargo. In series means one spring stacks after the other, like in some suspension systems. These springs essentially provide the performance of an optimized stacked spring set-up but in a single spring. Look at the Dual Rate Spring in the image above. To figure the combined spring rate just (200 x 300) divided by (200 + 300) next (60,000) divided by (500) equals 120 lb combined spring rate. Spring Rate Formula. In a multi-spring system, the misconception is that the first spring will carry the entire load before the second spring begins to compress. Nov 28, 2022 · The first thing we need to do is determine the active spring rate that we have. If you stack a 10-inch 200 rate and 6-inch 200 rate spring, you get a combined rate of 100 pounds per square inch. Example 10" 100lb/in upper 12" 200lb/in lower Our spring rate calculator can easily derive the spring rate (spring constant) for any spring, given some of its properties. This calculator tells you how stiff the setup feels as a whole. When in doubt, choose a lower spring rate. The Springulator is viewed as the best and most robust spring calculator resource by industry professionals, with easy-to-use functions, reference diagrams and stress charting. 2. You should always find the closest spring rate available for your application. For single rate that number is the rate of your spring as advertised by the manufacturer, for dual rate we use this formula to determine active rate, (upper rate x lower rate) / the sum of the upper and lower = active rate. Lets run a 200 lb upper spring and a 300 lb lower spring. Facebook Twitter For single spring coilovers your calculation is done. This Spring Rate Calculator will help you to find an approximate spring rate for your coil-over application. This article will show you how to use this Omni Calculator spring compression tool. It is calculated by dividing the product of the top spring rate and the bottom spring rate by the sum of these two rates. (A-Arm, I-Beam, Four Link rear, etc. We need to know the suspension configuration as well. See full list on crawlpedia. Determine the ideal spring rate for your vehicle with Donerre’s Spring Rate Calculator, designed to deliver precise results for optimal performance. Based on the example above, you would want to find a spring rate close to 110 lbs/in. Example: Do not exceed 70/100. May 12, 2015 · To figure spring rate, we must know the vehicles WHEEL TRAVEL, SPRUNG WEIGHT, and DROOP PERCENTAGE. I set it up for triple coil (main, tender & helper) combinations, and it works for dual coil systems as What is a Dual Spring Rate? The dual spring rate is the effective spring rate of two springs combined in parallel. Skip to Content (800) 507-2338 Mon-Fri 6:30a - 4:00p PST Corona, CA The handy spring calculator expresses the relationship between the force or torque applied to a spring and its deformation. Now in this Dual Spring Rate system the first 2 inches of travel you are feeling 120 lb spring rate in your butt. If your suspension isn’t drooping properly over bumps and rebound is set correctly, try increasing the preload while using softer spring rates. 69") of travel and a 65 mm stroke shock, giving it an average leverage ratio of 2. Dual Rate Springs are excellent springs for long travel suspension systems. Coilover Dual Rate Nuts. This calculation is useful in mechanical systems where springs are used to provide a specific stiffness or Dec 16, 2013 · Dual Rate Springs are generally more expensive to make, harder to design, and harder to inspect than linear rate springs. Aug 13, 2024 · Enter the top spring rate (N/m) and the bottom spring rate (N/m) into the Dual Spring Rate Calculator. You may not be able to find a 16-inch 100 rate spring, so this provides more spring length to use. This tool is an essential resource for anyone looking to fine-tune their suspension system. Share this post. Stacked Spring “Combined Rates” Chart. Here is a general process basics guide for calculating spring rates for a dual rate coilover:1. Start with the springs and shocks installed on the vehicle. What is a Dual Spring Rate? The dual spring rate is the effective spring rate of two springs combined in parallel. Enter a value of 12 for the pitch in the centre section, and the spring looks like this: That's it! Our spring has been designed. com Get your custom coilovers right the first time using our spring rate calculator! Works for single and dual spring setups! Contact us with questions! Oct 3, 2024 · The formula to calculate the dual spring rate is: DSR = \frac {T \times B} {T + B} DSR = T + BT × B. The first and most crucial step in improving handling performance is designing your springs to work with coilover Feb 24, 2022 · Here's an example I recently reviewed the Starling Spur, which has 170 mm (6. It's easy to use with accurate measurements. It is easier to achieve handling and performance with a lower spring rate and a “stiff” stabilizer bar or shock. Longer Lower Springs Spring Rate = Static Load / Shock Ride Height. Nice and plush. THE NEWCOMB SPRING SPRINGULATOR® Compression Spring Calculator; The industry's most advanced spring calculator. Dual Rate Coilovers (8" to 16" Coilovers) Dual rate coilovers use two springs, so you will double the required spring rate and split the difference. Increasing the spring rate is the simplest way to improve handling, with minimal performance loss, since rebound damping can be easily adjusted to match the new spring rate. The calculator will evaluate the Dual Spring Rate. This calculation is useful in mechanical systems where springs are used to provide a specific stiffness or Dec 30, 2024 · Follow this procedure if you have just purchased new springs or coilover shocks from us. spring. Because the leverage ratio barely rates, to achieve a longer spring that is softer rate than either of the springs used. A dual rate spring needs to have two sections of active coils at different pitch. Also, we will cover what the spring compression formula is and how to calculate the spring constant for different configurations. With a dual rate coilover setup, the softer spring should not be less than 70% of the stiffer rate.
