Weight Optimization Of A Lift-Tipping Mechanism For Small Solid Waste Collection Truck

Abstract: This paper deals with Optimization of a lift-tipping mechanism for a small solid waste collection truck. Finite element analysis was performed on a linkage mechanism that operates the tipping mechanism. The exercise involved validating the design changes made in the stress analysis environment. The work flow was repeated until the weight of the designs was optimized against the design criteria. Siemens Solid Edge ST3 software package, NX Nastran (7) solver was used in the optimization process. The weight of the linkage mechanism has been reduced from 11.6 kg to 7.5 kg which represents 35.4% reduction in weight.
