Strength Analysis and Optimum Design of Dynamic Compaction Machinery Boom

Abstract:

Based on UG NX7.5 and a certain dynamic compaction machinery whole model, strength analysis and optimum design of boom were studied. After determining the dynamic compaction machinery working loads, based on finite element analysis method, by comprehensively considering lifting, unhooking and rated load conditions, the stress and displacement contours were obtained. The error of experimental and calculated values was less than 15%; furthermore by taking into account of the rationality and security of design and manufacture, the structural optimization of boom in lifting and unhooking conditions was studied. By comparing to the original structural, both the stress and displacement performances of the optimized one was greatly improved, with a 6% and 18.6% increase in maximum stress in lifting and unhooking condition respectively, a 3.9% and 5.6% reduction in maximum displacement and a 6.52% reduction in mass.
