Modeling, Analysis And Optimisation Of Telehandler Components

Abstract

This dissertation illustrates the application of CAD/CAE technologies for the design validation and redesign of the existing components of the telehandler by doing finite element analysis depending on the practical operating conditions. An attempt is made to analyze the telehandler chassis and dipper arm for various load-carrying conditions. Now a day’s telehandler are playing a vital roll in manufacturing, agriculture and material handling purposes in general. A major company, which is a manufacture of various varieties of telehandler, wants to check its design validation and redesign of existing components depending on the analysis results. By applying CAD/CAE technology, firstly a solid model of the telehandler chassis assembly is created in PRO/E 2001 and mid surfaces are extracted and assembled in the default coordinate system in PRO/E itself. Afterwards it is exported to hyper mesh for meshing (dividing into finite elements).The finite element model is then imported in IDEAS for analysis as a Nastran bulk data. Static force analysis is performed in DESIGN VIEW and various reaction forces acting on the telehandler chassis at telescopic boom hinge point and cylinder hinge point are calculated. Total five load cases are considered for finite element analysis of the telehandler chassis. In the similar lines modeling, static force analysis is done for dipper arm. The dipper of the telehandler is safe in condition. It is observed that the chassis is failing at the hinge points so the telehandler chassis is redesigned depending on the stress limit.
