ZHANG Tiemin, LI Wentao, LIANG Li. Multi-objective optimization design for turntable of dead pig vehicle based on sensitivity analysis[J]. Journal of South China Agricultural University, 2017, 38(5): 103-109. DOI: 10.7671/j.issn.1001-411X.2017.05.018

To improve the working performance of dead pig vehicle and cut down the costs, multi-objective optimization design was carried out on the structure of turntable.
By using the Creo Simulate three-dimension design software, the statics finite element analysis and sensitivity analysis of the original turntable were executed．Based on the above analysis, a multi-objective optimization design model for the structure of turntable was built．The optimal design scheme was selected using the fuzzy matter-element analysis method and weighted average method.
The multi-objective optimization design model for the structure of turntable was built, and six groups of non-inferior solution were obtained. The optimal design scheme was obtained by evaluating and preferring. Comparative analysis on parameters before and after optimization showed that the turntable mass after optimization was 20.90 kg and reduced 19.43%. The maximum equivalent stress was 1.44 MPa and reduced 4.00%.
The proposed structural optimization design for the turntable of dead pig vehicle based on sensitivity analysis is reasonable and feasible. The result can provide the theoretical guide for improving turntable structure.
