Methods And Systems For Spring Design And Analysis

US Patent:
2006014, Jul 6, 2006
Filed:
Dec 30, 2004
Appl. No.:
11/024723
Inventors:
Sami El-Sayed - Bloomington IL, US
Avtar Sandhu - Bloomington IL, US
Dana Coldren - Fairbury IL, US
Rabah Seffal - Bloomington IL, US
International Classification:
G06G 7/48
US Classification:
703007000
Abstract:
A spring design method is disclosed. The method begins with inputting a first set of design parameters for a spring. The design parameters include a parameter that provides an estimate of non-linearity in the spring. The spring design method determines a spring design based on the first set of design parameters. A spring design and analysis method is disclosed. The method begins with creating a spring design. The spring design includes a parameter that provides an estimate of non-linearity in the spring design. The spring design and analysis method creates a spring animation file that enables stress levels in a spring design to be identified at the coil level. The spring design method next identifies the coil in the spring design having the lowest dynamic fatigue factor and determines whether the lowest dynamic fatigue factor is acceptable.
