The Design And Research Of Comfortable Soft Sleeper In Direct Express

China has a large population, a large population, the economy and the fast railway passenger transport services in the transport and economic development plays an important role. At present, the vast majority of China’s long-distance passenger transport conditions are reflected in the railway above. By the end of 2010, the mainland of China’s railway passenger turnover is 981233 km, ranking first in the world in other countries. The direct express train because of its moderate price, speed, short time by long-distance travel transit passengers of all ages, in the season to travel the overnight North Korea to the sleeper seat is hard to get a vote. At present, due to the long cycle of the train production, the update is slow, and the environmental conditions in the car are becoming increasingly difficult to adapt to the demand of the passengers gradually increasing. The research of this thesis is the first to start from the running status of the direct train and the market demand analysis of the sleeper train. The market research shows that the majority of passengers have a huge demand for long-distance sleeper train. In the face of such a large demand, the interior decoration and design of the non high speed train of non high speed train has not been updated for many years. Because of the lack of theoretical practice in ergonomics,aesthetics and environmental psychology.In the course of the study, the sleeper design case of Europe, America, Japan and other countries was collected, and the different design strategies of the sleeper compartment were studied. And the development of the sleeper car model is reviewed, and the comparison and analysis of the various types of sleeper design are made. Then, from the overall system of the people- car- environment, the interaction between passengers and passengers is studied,and the factors affecting the comfort of passengers’ body and psychology are analyzed. The data used in the research stage collect positioning a soft sleeper, take the population,through interviews and field observation survey method in-depth sleeper passengers ride in the process in the face of the main problems, and analysis of its causes and improvement.Based on the existing basic design standards of the train, the analysis of the interior space design of the train compartment is focused on the analysis of the characteristics and the design of the scheme. According to the results obtained from the above analysis, research,analysis, and analysis of the main points of the design and innovation, to solve the above problems to complete the design, and for which the most reasonable solution to achieve its vision and specific design.
