The Application of Finite Element Methods in the Design of Cylinder Block Gaskets for the Wobble Plate Type Compressor 900217
The implementation of rubber coated metal gaskets, (RCM), into refrigerant compressors is valued not only for its replacement of the asbestos fiber material, but for reliability enhancements as well. The design of the gasket, however, must be considered because flat RCM gaskets do not have equivalent compressibility as compared to flat fiber gaskets. This can result in refrigerant leaks when flat RCM gaskets are used due to inadequate load distribution.
Using Finite Element Analysis, (FEA), an embossment was designed for the RCM material which provided a well distributed seal pressure. Prototypes of the embossed RCM gaskets were created and their function empirically verified.
