Barycenter Error Evaluation and Correction for Modular Marine Propeller

Liang Yande;Sun Jiefu;He Fuben;Lu Yaheng;Dalian University of Technology;  
In the process of blade manufacturing,there existed the influences of manufacturing precision,material defects,assembling errors and other non-design factors,which caused the difference between actual position and theoretical position of modular marine propeller barycenters. There would have adverse effects on its mechanical properties. Hence,it was necessary to evaluate the barycenters and remove the weights so as to correct the barycenter position errors of relevant blades. The concepts and the algorithms of minimum containing ball and removal processing ball were proposed,which could be applied to determine whether the blade needed to be re-processed. Meanwhile,regarding the barycenter combination,two weight correction solutions were also proposed based on the principles of the minimum amount of correction weight and the minimum dispersion degree of barycenter respectively. In the end,the feasibility of strategy was evaluated by applying theoretical analysis and simulation experiments.
