Abstract
Improving of the quality of the disc cutters’ plane layout design of the fullface rock tunnel boring machine TBM is the most effective way to improve the global performance of a TBM The plane layout design of disc cutters contains multiple complex engineering technical requirements and belongs to a multiobjective optimization problem with multiple nonlinear constraints Based on analysis of the technical requirements of the plane layout problem an optimizing mathematical model was built To obtain a set of design schemes for engineers to choose from a multiobjective genetic algorithm MOGA was applied to carry out the optimization of the mathematical model A constraintdomination principle was utilized to handle the constraints and a nondominated sorting method was adopted to obtain Pareto solutions Simulation results showed that the proposed method was efficient and accurate in obtaining the Pareto layout solutionsJunZhou Huo received his BS in Mechanical Engineering from Henan University of Science and Technology China in 2001 He then received his MS and PhD degrees from Dalian University of Technology in 2003 and 2007 respectively Dr Huo is currently a postdoctor at the School of Mechanical Engineering at Dalian University of Technology in Dalian China His research interests include layout optimization and TBM cutter head designWei Sun received his BS in Mechanical Engineering from Dalian University of Technology China in 1988 He then received his MS and PhD degrees from Dalian University of Technology in 1993 and 2000 respectively Dr Sun is currently a professor doctoral supervisor at the School of Mechanical Engineering at Dalian University of Technology in Dalian China His research interests include knowledgebased product digital design design and optimization of complex mechanical equipmentJing Chen received her BS in Mechanical Engineering from Henan University of Science and Technology China in 2000 She then received her MS degree from Dalian University of Technology in 2006 Chen is currently a PHD candidate at the School of Naval Architecture Engineering at Dalian University of Technology in Dalian China Her research interests include optimization design and CADPengCheng Su received his BS degree from Dalian University of Technology China in 1982 He then received his MS degree from Shenyang University of Technology in 1988 Su is currently a chief engineer of Nhi Group Tunnel Broing Machine Company in Shenyang China His research interests include TBM design large bucketwheel excavator design and MWclass wind turbine designLiYing Deng received his BS degree from Shengyang Institute of Technology China in 1998 He then received his MS degree from Northeastern University in 2006 Deng is currently an engineer of Nhi Group Tunnel Broing Machine Company in Shenyang China His research interests include TBM design
