Weight Reduction of Structural Vibration Isolation Hydro-Mount Bracket Through Design Analysis and Use of Advanced High Strength Steels

摘要

Vibration Isolation Mounts are designed to isolate noise, reduce resonant vibration and lower structure-borne noise. The external mounting bracket that encases the fluid-filled inner mount is usually made from relatively thick (～3mm) high-strength, low-alloy steel and has critical structural and durability requirements. In this study, a practical approach combining FEA and physical testing was used effectively in component design with complex functional requirements. A new lighter-weight configuration with ～8% weight savings was validated to pass all the structural and durability requirements.
