Abstract:

Even the best-designed engineering products can suffer from failures early in their lives either as a result of inadequacies in the design itself or caused by external conditions and unrestricted events. Failures are not easy to analysis and the precise mechanism of failure can often be difficult to identify. The objective of this study is to look briefly at what happens when crane sheave fails and to introduce the activity of redesign necessary to stop the failure recurring. For this a crane sheave is design as per standard BS 466 and shows how some simple design improvements are used, by following a design review and analysis of the failure. For the analysis purpose conventional FEM tool is used with load and boundary condition similar to reality and found that crane shave subjected to fail from the top edge due to excessive stress concentration and hence new modified design is suggested.
