Abstract
The technical memorandum describes the development of finite element models of helical compression springs with closed ground ends. These models are to be subsequently used in finite element based procedures for the design and analysis of machinery vibration isolation systems employing helical spring mounts. Solid finite element models, constructed with 20-node hexahedral elements, and simplified beam element models are considered. The natural frequencies of vibration are predicted for both unloaded and statically compressed springs using the DREA in-house finite element code VAST. Comparisons are made with experimental data and with results obtained using a beam transfer matrix method.
