About company
More than a spring calculator, ODOP:Spring is full-featured spring design software for engineering custom helical coil springs, including compression, torsion and extension springs. While certainly capable of analyzing the performance of an existing spring design, our open-source and free to use web app is at its best when used to develop solutions to difficult and highly constrained original design problems. Typical spring calculators perform design analysis, requiring users to make repeated inputs (independent variables of the design equations like wire diameter, coil diameter, number of coils and loads) until the desired outputs (dependent variables like deflections, stresses, weight, and estimated cycle life) are achieved. On the other hand, ODOP:Spring performs design synthesis to invert the dependent / independent relationships of the design equations and perform constrained optimization. You input specific goals, and ODOP:Spring returns the variable values that best meet those goals.
