PARAMETRIC COMPUTER AIDED DESIGN OF NON-H CLOSED EPICYCLIC GEAR TRAINS BASED ON MULTI-OBJECTS FUZZY OPTIMIZATION

Non-H closed epicyclic gear trains characterized by large transmission ratio,high power,high efficiency,simple and compact structure are researched on ranges of the modeling,the fuzzy optimization design of multi-objects and multi-cons-traints and the parameterized design of assembly drawing and main part drawings.Based on analyzing the structure and characteristics of non-H closed epicyclic gear trains,a mathematic model of the fuzzy optimization design of small volume and high efficiency is put forward,and the non-fuzzy process of the fuzzy factors are accomplished.The results of the optimization design show that the method of the fuzzy optimization design of multi-objects and multi-constraints takes into account not only the whole property of the gear trains but also the fuzziness of objects and constraints,and gets an optimum level of the entire objects.By computer aided design(CAD) technology,the design pattern of non-H closed epicyclegear trains is standardized.The software of non-H closed epicycle gear trains parametric CAD is programmed.The parametric design of the complex gear trains is realized.
