Belleville springs are important type of springs. They are frusto-conical in shape. Nowadays, they are extensively used because they occupy less space and support high load with small deflection. Load-deflection characteristics of a Belleville spring can be altered by introducing holes in the springs. In this research work, Finite Element analysis of Belleville spring and experimental investigation using strain gauge was carried out. Finite Element analysis was carried out on a plain spring and results are compared with theoretical analysis. Analysis was also carried out on Belleville spring by introducing holes. It was observed that Load-deflection characteristics can be altered by introducing holes which can be used as an advantage. Experimental investigation was carried out using strain gauges for different configuration of Belleville springs such as plain spring, spring with holes. From the studies it was observed that Theoretical, Finite Elemental and Experimental analyses were in good agreement. When holes were introduced, the magnitude of maximum stress was increased by 20%. Thus, when a slight increase in stress is tolerated, a given load-deflection characteristics can be achieved by using springs with holes. Moreover, Belleville spring and helical spring combination can be used to develop high deflection load cell.
