Maximum spring compression calculator1/28/2024 ![]() Standard and custom springs are available. Using the values in the first example, (If a spring has a 5-inch length, the spring rate of and will travel 2 inches), you can calculate the amount of spring rate needed to travel down to a loaded height of 3 inches using the formula above. When designing for a particular spring, design for critical loads and rates to be within the central 60% deflection range. The final 20% of deflection shows considerably higher spring rate. The final velocity of the block that I calculated correctly (finally) was 10.727 meters. compression (1.914 meters) of the spring, but Im assuming this makes sense since the spring constant was only 20 N/M and the block had only traveled a bit more than 5 meters at this point. Because of end-coil effects, the first 20% of deflection range has a considerably lower spring rate. Thank you I received a rather small number for the max. The spring rate tends to be constant over the central 60 percent of the deflection range. Spring rate can be measured by taking the difference in force at 80% maximum deflection and 20% minimum deflection and dividing by the difference in deflection. Torsional Correction Stress of Compression Springs This calculator computes all parameters (spring rate, maximum load, maximum stress. Therefore, the height (H) to the n (th) coil measured from the maximum coil diameter under no load can be expressed by the following formula when the pitch angle () is small. Open -> Helical Compression Spring Design Calculator In a conical coil spring with a fixed pitch angle, R and n’ ( / 2) are associated with the following formula. ( This calculator requires a java - enabled browser) K = Spring constant determined by experiment or calculation ( Calculate k Constant) This Helical Compression Spring Design Equation will determine force from the given variables.ĭ Standing = Free length of spring (inches)ĭ Deflected= Length of spring with force applied (inches) ![]() This can be represented by the equation F -kx, where F is the force, k is the spring constant, and x is the displacement of the spring. ![]() Helical Compression Spring Design Equations and Calculator The maximum distance a spring is compressed can be calculated using Hookes Law, which states that the force exerted by a spring is directly proportional to its displacement from its equilibrium position. ![]()
