A valve spring retainer is a small disc and located at intake and exhaust valve stem of engine. The
retainer supports a valve spring and transmits spring force to a valve. Force is applied to the retainer
repeatedly by a rocker arm. Durability of the retainer is an important factor of performance. Weight of
retainer affect dynamic performance of engine. Therefore, optimal strength and weight of the retainer design
are needed.
In this study, stress distribution and fracture load of retainer were analyzed by using FEM to design
optimal strength and weight. Static load test was simulated by using commercial FEM code DEFORM-3D.
Shapes of the retainer to reduce weight were designed and analyzed to verify validity of it. Simulated results
and experimental ones were compared
