The force analysis and strength analysis are important steps in the design of excavator parts. Finite Element Analysis (FEA) is the most powerful technique used to evaluate strength of the structures working under high loads. This paper focuses on the solid modeling of the mini hydraulic backhoe excavator intended for light duty

A recent trend in the development of off-highway construction equipment, such as excavators, is to use a system model for model-based system design in a virtual environment. Also, control system design for advanced excavation systems, such as automatic excavators and hybrid excavators, requires system models in order to design and simulate the control systems.

Jul 16, 2012 · As the industrial arena grows more sophisticated, it seems as though operations are confronting fewer and fewer broken machine shafts. When shafts DO break, however, there are almost always as many theories regarding the suspected culprits as there are people involved. Fig. 1 The appearance of an overload failure depends on whether the shaft material …
