Abstract
Rubber springs are widely used in industry as antivibration components giving many years of service. The Metacone range of mountings is well established as an antivibration mounting, suitable for engine suspension, where vertical and horizontal movement is controlled within the design. The Metacone mountings manufactured at Trelleborg-AVS are designed for maximum load capacity combined with a large deflection in an axial direction. An integrated design procedure (including material and prototype testing and finite element (FE) analysis) has been carried out to evaluate the component unit to meet customer requirements. The geometry data were imported from a computer aided design (CAD) system to a computer aided engineering (CAE) system. A solid three-dimensional model with appropriate mesh was generated for FE analysis. Detailed stress analysis was conducted, and conclusions from the FE results suggested that the assembly of the Metacone mounting unit is safe for prototype testing. The ultimate load test on the prototype unit was carried out in the present authors' laboratory, and the result has shown that the component has met customer requirements. Now the products have been manufactured and delivered.
