Modeling and Analysis of Composite Helical Compression Spring

The challenges for the automobile manufacturers are to improve the quality along with the performance of the components and reduction in weight and manufacturing cost. Therefore, the investigation is going for alternative materials to design automobile parts and improves the strength to weight ratio, which is fuel-efficient. As alternative materials, composites are used widely. The use of composite material produces in mass level which reduces the manufacturing cost and higher strength. The present work is keen to study the feasibility of composite helical compression spring used in suspension systems. The comparative study was done with conventional steel IS4544 Grade 3 (Tata Indica Vista) helical compression spring to the composites helical spring in the present study on a load of 4542.3 N. EGlass/Epoxy and IS4544 Grade 3 are used as the composite constituent, in which EGlass/Epoxy is used inner or outer layer and IS4544 Grade 3 vice versa. Composite helical spring has found better mechanical properties than conventional. Solid works 2013 is used for the modeling of helical compression spring, and commercially available ANSYS 14.5 software is used for the static and modal analysis. It is observed from the study that stresses and deformation generated in the composite material helical compression spring are reduced, and strain energies stored by the composite material helical compression spring are increased.
