Extension Spring Design Software

More powerful than a spring calculator, ODOP:Spring is a full-featured web app enabling the engineering design of coil springs.

Get Design Solutions for Any Extension Spring.

More than a spring calculator, ourĀ free and open-source ODOP:Spring software helps to remove the guesswork involved in designing an extension spring.

Express your design goals by setting constraints or fixed values on variables such as spring rate, spring force, spring weight and cycle life. Our full-featured extension spring web app will then find the best design solution.

If a feasible solution cannot be reached within your specified parameters, ODOP:Spring’s Search feature will converge to a compromise solution for your extension spring design.

In this situation, ODOP has a feature that may be used to identify those constraints that are most leveraged and guide you to restructure your goals in a way that is most consistent with your original objectives
