Abstract
Provides documentation and operating instructions for the FORTRAN computer program SPRING2. This code is used to generate the geometry of a helical compression spring with closed ground ends. The primary output of the code is a PATRAN session file which can be run in PATRAN to generate PATRAN Phase 1 (geometry) and Phase 2 (finite element) models automatically. A PATRAN neutral file is then created which the program PATVAS can convert to a VAST finite element model. The program can be used to generate a session file for a full solid finite element model, constructed with 20-noded hexahedral elements, or for a simplified line model in which the spring helix is modelled with a string of beam elements following the spring wire centre-line.
