Paper Title:
An Improved Optimization Method on the Material Mixture Ratio of Ship Stern Bearing
  Abstract

An improved optimization method on the material mixture ratio of ship stern bearing is proposed. During the optimized experiment of ship stern bearing material mixture ratio, uniform design and partial least-squares regression are used to extract the regression function between the optimization object factors (including friction coefficient of the stern bearings, abrasion loss in unit time)which can evaluate the performance of ship stern bearing material mixture ratio and the other experimental factors(including the material mixture ratios of stern bearing components, stern bearing processing temperature).The total optimization object function is composed by the proper weighting to these obtained regression functions.The optimized material mixture ratio will be attained when the comprehensive evaluation index which is the value of the total optimization object function gets its optimum value. Through an analytical comparison with existing optimization method , the improved optimization method can greatly reduce testing times and the experimental cost, shorten the experiment period in the allowed precision range. Based on the experimental analysis of a technology simulation model of related ship stern bearing, it shows that the improved optimization method is practicable and effective.
