Fatigue Analysis and Experimentation of Two Wheeler Valve Spring

Bharathrinath Gorakhnath Kadam | A. B. Ghalke | P. H. Jain | A. Z. Patel

Abstract: Springs are mainly used in the industry as members absorbing shock energy as well as for restoring the initial position of a part upon displacement for initiating a given function. Compression springs are coil springs that resist a compressive force applied axially. In every two-wheeler valve springs play an important role in controlling the breathing in internal combustion engines. The valves are mechanically opened by a camshaft, via valve lifters or tappets, and closed by the valve springs. The analysis would indicate the prominence of the design parameter and its effect over the performance of the spring in terms of fatigue life. The work would be pursued to conclude with a proposal specifying the suitable values (levels) for the significant parameters identified for this study. References are drawn from the literature review as well as the industry. So it is important to calculate the fatigue life and reduce fatigue failure in its intended working period.
