Broad-Gauge Bogie Design Of CKE1 High-power Electric Locomotive

Railway transportation has become an important transportation mode in many countries, because of its clean, high speed, large capacity, high security advantages,low cost and so on. The performance of the locomotive is an important part of the railway transportation. The world famous locomotive manufacturers are constantly upgrading their technological strength And do their best to develop a superior performance locomotive products for different users. They have occupied the majority share of international locomotive market, because of their early start and rich experience.In recent years, Chinese locomotive industry has made a leap forward development, gradually enter the international market, occupy some market share.China manufacturing locomotives gradually enter the international market, occupy a part of market. At present, Chinese main locomotive manufacturing factories have export many products which has superior performance to many developing countries and even developed countries.However, long-term since, due to different historical, national conditions, and many other reasons, railway transportation gauge is difficult to unifiy in different country of the world. Countries in the world main use standard gauge type, narrow-gauge type and broad-gauge type. Chinese railway is standard gauge type, there is no non-standard locomotive used in China, therefore the export locomotive's bogie design must according to the requirements of export country's gauge. It's the first time for Dalian Locomotive & Rolling Stock Co., Ltd. that CKE1 locomotive as high power broad gauge electric locomotive products export to a central Asian country, R&D broad gauge electric locomotive products could help the domestic locomotive industry to realize the diversification of locomotive products, expand the international market, enhance their competitiveness.The paper defines the design idea of the bogie at first, by using the HXD3 high-power AC electric locomotive technology platform which has rich experience in design and application, and combined with the complex parts structure design's concept unit method. Design of broad-gauge high power AC electric locomotive according to the railway standard which is used in Russia and the Central Asian countries.The main research work of this paper is as follows:(1) Introducing the background and research areas of the topics, for a simple understanding about broad-gauge electric locomotive's development of the domestic and foreign locomotive supplier, and elaborated the research significance of this topic.(2) Designing bogie on the technology platform which has been set up, and construct a basic geometrical physical model of bogie which can satisfy function at first.(3) Using newly designed parts and modular component which have been chose to perfect the geometry of the physical model which has been constructed. To get good performance of structure and layout.(4) Making stiffness and strength design of the bogie's 3D solid model which has been built. Analysis that if the stiffness and strength of the bogie can meet the relevant standards. Finally, get the structure and layout which can be met the strength and stiffness requirement.And meantime, evaluate the product's fatigue life.(5) According to the CKE1 broad-gauge high power electric locomotive bogie's structure and suspension parameters, using the SIMPACK which is a software about multi rigid body dynamics analysis,construct dynamic analysis model of locomotive. Through comprehensive analysis and calculation of locomotive dynamics, analysis and prediction the dynamic performance of the locomotive.
