Structural Analysis & Optimization Design Research Of Process Bogie Based On AWE

Rail transport plays an increasingly important proportion and role in the economic and social development,and China's railway development is at a critical period of rapid development. According to China's railway construction plan, the total mileage of China's high-speed railway will be exceeded 18,000 km by 2020,at the same time China will have the largest high-speed rail network in the world, accounting for almost half of the total high-speed railway mileage. Motor car and high-speed rail's development speeds up China's economic and social overall development, but also leads the world economic and social development, so Motor car's fast, safe, smooth operation and maintenance work are particularly important. EMU maintenance is divided into five level, usually when one, two level of maintenance the entire line enters the maintenance base;when three and above the level of maintenance, Motor car body and bogie are separated, at this time the equipment is needed to support and carry the body. In this paper, motor car for three and above maintenance requirements, to design a new process bogie. Process Bogie is the special tooling equipment,to meets the needs of various types of motor car, to replace bogies, to carry the body to complete body to move between the repair station after the separation of the body and the bogie. At present, many countries have attached great importance to the locomotive maintenance problems of key parts, and process bogie enables different train fast maintenance, dispatch services. Reliable design and analysis of the process bogie is particularly important, not only affects the efficiency of the locomotive repair, but also for the safety of motorcycle repair quickly replace or play irreplaceable role to man-made.In this paper, this motor car process bogie used CAD/CAE technology is a process equipment that can bear,transport four motor car body; combine with ANSYS Workbench software for key parts of process bogie to finite element analysis and optimization design research. The main research contents and the results are as follows:(1) Combining the railway industry standards and process bogie technical specifications [1], design a process equipment to meet the domestic motor car different type (including CRH1,CRH2,CRH3,CRH5). Make use of CAXA software to complete preliminary structural design for process bogie. The innovation is to use lateral movement slide to move in the dovetail slot, to adjust the horizontal width for meeting the needs of different body widths.(2)Make use of three-dimensional design software Pro/ E to finish three-dimensional model construction of key components for the process bogie preliminary structural design. With the actual process conditions, carry out the static strength analysis, fatigue analysis, and structural dynamics modal analysis of the key components of the process bogie in the ANSYS Workbench Environment (AWE) environment.(3) The optimization of frame and beam is the core problem for lightweight process bogie optimization design. Materials and structures shape in the same circumstances, optimize the size of the main structural for frame and beam in the AWE Environment, and achieve significant results.
