Abstract An open coil and closed coil helical springs works usually under critical conditions due to the continuous variations of load acting on the top surface. The analysis of an open coil and closed coil helical springs of an automobile clutches are carried out in ‘ANSYS’ software and the experimental study has been conducted for different load conditions. The various parameters like total deformation, stress intensity, strain energy and equivalent von-misses stress are considered for study. An experiment has been carried out for total deformation of an open and closed coil helical springs at various loads like 500, 1000 and 1500 N. The experimental results shows a good agreement for the simulation results. The results shows that the performance of an open coil helical spring is good compared with closed coil helical spring.

1 Introduction A spring may be defined as an elastic member whose primary function is to deflect or distort under the action of applied load; it recovers its original shape when load is released. Coil springs are manufactured to very tight tolerances to allow the coils V.C. Sathish Gandhi (&) M.

spring to precisely fit in a hole or around a shaft. Most structures are designed will undergo acceptable deformation under specified loading conditions, but their main requirement is to remain rigid. A spring, however, will store energy elastically due to its relatively large displacement. The various application of springs are used to absorber shocks, applying forces in brakes and clutches, to control the motion between cams and followers and store energy in watches, toys etc.,. To ensure the application of springs the study of performance of coil springs are very important.
2 Literature Review The literature of the coil springs are composed based on the information from the simulation techniques and its applications. Gaikwad and Kachare [1] presented the static analysis of helical compression spring used in two-wheeler horn. In this work the safe load of spring is calculated analytically and compared with Simulation results. The simulation is performed in the NASTRAN solver. Patil et al. [2] studied the comparison of cylindrical and conical helical springs for the
