Controlling exterior noise by advanced sealing systems design

摘要

Controlling exterior noise intrusion involves a complex array of variables, such as seal geometry,rnclosure geometry and trade-offs between closure force/pressure and seal material properties. Thernavailable CAE tools require engineering expertise and excessive time, and laboratory testingrntakes place in the final stages of design verification. The results from these methods are oftenrninconclusive, leading to expensive changes at prototype stage when physical testing reveals thatrnthe initial seal section geometry needs modification. At this stage, time and cost considerationsrngenerally make it very difficult to modify the design. EASi-SEAL, a design-oriented alternativernto the conventional methods, is changing this trend by catching design problems in seal sectionsrnand closure environment early in the product development cycle, long before a physicalrnprototype is built.
