Design and parametric characterization of flexure bearing as automotive valve spring replacement

Automotive valve springs occupy substantial space in the cylinder head of an internal combustion engine and contribute to frictional loss. In this paper, the design and analyses of a flat spring concept, known as flexure bearing are presented. Flexure bearing act like a typi...
