The Research On Modeling Design Of Electric Road-rail Tractor Based On The Geometry

With the development of the railway in China,the safety and efficiency of railway transport have been paid more and more attention.The function of electric road-rail tractor is train traction and dispatch,especially safety detection and fault maintenance when the tractor arrived at the maintenance base Manufactures in our country have been launching many electric road-rail tractor and put it into the practical work very wel.As the same time,many problems have been showed successively like poor appearance modeling,weak series feeling and ignoring the operating experience.These problems have been the reason of poor competitiveness in our country between the national and foreign market.The author takes the modeling design of electric road-rail tractor as research object based on the design of geometry.With the purpose of improving the effector of appearance,consolidating the seriation of the products and improving the operating experience,the research will follow this paragraph below.First,study the design of geometry,expounded the relations between the design of geometry and engineering machinery product modeling design.Providing the theory basis for design.Next,analyzing the functional structure of electric road-rail tractor deeply helps to clear the obstacles doing the research.Comparing the domestic and foreign product through market research,the products in our country show their major problems.Though analyzing the user,operating environment and mode,find out user needs.Then,apply the design of geometry to the appearance design of electric road-rail tractor and analyze its reason and meaning.Introducing the method of the design of geometry that using in modeling design of the electric road-rail tractor.Product standards is putted out through analyzing the objectives influence of design.Finally,apply the design of geometry to solving the problems which is found out by market research.Position appearance design of electric road-rail tractor as find target,Combine the design position needs and analysis needs,got the design scheme.Analyzing and evaluating the design results,get the design scheme and optimize the design.Show the design with the form of 3D modeling and write statement.Though the study,find the effective method,and guide the design of electric road-rail tractor,which improve the quality of product.Proved that the design of geometry is suitable for the appearance design of electric road-rail tractor.
