Optimization Design of Cab Structure in Power Concentrated EMU
摘要
Abstract
The cab structure takes the key role for the safety of driver inthe powder concentrated EMU.The structural strengthening by the design of reasonable load paths can be used for the structural weight reduction of the corner and collision pillars in the load case of collision under the condition of structural safety.This can be meaningful for designing the power concentrated EMU with heavy load and high speed.The topological optimization was used for the topology design of the cab structure in the power concentrated EMU,in which the distributions of the corner and collision pillars can be obtained.Based on the obtained re-generated structures,the geometrical size optimization is further used.Results indicate that the weight of the cab structure can be obviously reduced by integratingthe topological and geometrical optimizations under the condition of structural safety.In comparison with the initial design,the weight of the cab structure can be obviously reduced.All the weight of the new corner pillar andcollision pillar can be reduced by up to 67.5%.The weight of cab can be obviously reduced by the present integrating topological and geometrical optimization method.关键词
