The Application of Computer Modelling to the Design Optimisation of a Microexcavator Digging

An assessment of the parameters which must be considered for the design of microexcavator digging arm and hydraulic system has been undertaken.<br/><br/>Fundamental mechanics and structural theories have been used to develop a structural model of the Powerfab 360WT microexcavator digging arm under static or Quasi-Static loading conditions.<br/><br/>Practical strain gauge tests were carried out to assess the accuracy of the computer model with satisfactory results.<br/><br/>A design optimisation method has been developed using a structural model integrated with a hydraulic system model. A complete computer aided design software package has been written utilising these models, enabling the design engineer to analyse the effects of design changes to the digging arm structure or hydraulic system to optimise structural integrity and performance.<br/>
