Excavator bucket performs heavy duty work as a earth movers. Several high pressure- high impact loads come on the teeth of the bucket. Sudden impact on earth surface, high stresses and shearing loads try to damage bucket every time. But the bucket must overcome from all the forces and loads which are directly and indirectly affect the performance efficiency. After some duration the dynamic stability of bucket also get affected due to heavy duty work. Sometimes the modification is done to improve the life of bucket by means of attaching the extra metal plates. But by this the weight of the bucket gets increased. The dynamic stability of bucket is very important for bucket which may lose by increase in weight. Excavator bucket life is the very important issue, because it fails to complete its designed life. The major reason behind this failure is its working environment and modes of operations. Excavator buckets are designed to work in worst conditions, situations for long duration of time. During its working bucket undergoes with great amount of stresses, loads, jerks, deformations and it would be very difficult to withstand in such situations. In this paper the design of bucket is tested in CAE tools. Also, the CAD tool will help for the creation of virtual excavator bucket design. Several tests like, structural analysis, vibration analysis, shape optimization, crash test etc. will give the behavior of excavator bucket during working condition. Also, the change in bucket material may provide the extra dimension to the study. Hence the complete dynamic performance is checked by applying loads with respect to time and cycles. Collective results will give the helpful conclusions which will improve the bucket life. Again, by changing the design and performing all related test will provide the optimized design solution for the excavator bucket life improvement which is the main aim of this project.
