Helical Compression Spring Design Software
More powerful than a spring calculator, ODOP:Spring is a full-featured web app enabling the engineering design of coil springs.
Set Design Goals. Get Solutions.
Free and open-source software, ODOP:Spring goes beyond the capabilities of a typical compression spring calculator.
Set your design goals by placing constraints or fixed values on variables such as spring rate and spring force. Our full-featured web app will then find the best design solution for your helical coil spring without the need for guesswork.
If our compression spring design software determines a feasible solution cannot be reached within your specified parameters, its Search feature will converge to a compromise solution.
From there, ODOP:Spring’s Trade feature can provide guidance to a workable design while ensuring the least possible compromise of your original design goals.
View the features page for more details.
