Research On The Type Of P_160E Movable Sidewall Cover Wagon

The frequent transportation of railways and the cross-running of passenger and freight wagons have caused the shortage of transport capacity in China.According to China's"Mid-and-long-term railway network plan?adjusted in 2008?",by 2020,passenger cars and trucks will be transported on separate lines to improve the truck's transportation capacity.At the same time,more trucks will be used to meet the transportation demand.With the deepening of the"The Belt and Road"and the rapid development of CHINA RAILWAY Express put forward new requirements for the development of railway freight equipment.Nowadays,railway transportation is mainly developing towards fast and heavy load.After the efforts of product researchers in recent years,the heavy haul freight cars have achieved outstanding achievements in terms of technology,but the rapid wagon technology is slightly lacking.As China's GDP steadily rises,transportation demand is toward the direction of high value of goods,strong timeliness,and individual product direction,which are also the main direction for the development of railway express transportation.Drawing on the experience of foreign express transportation,the development of the type of P_160E60E movable sidewall cover wagon side wall cover wagon has important practical significance.This article takes the type of P_160E60E movable sidewall cover wagon side wall cover wagon as the analysis object,and refers to the development status and characteristics of domestic and foreign rapid wagon.The technical problems that need to be overcome to develop the type of P_160E60E movable sidewall cover wagon side wall cover wagon are discussed in the following aspects:Firstly,the main technical parameters of domestic and international express railway freight transport equipment were studied.Secondly,the restrictive factors of developing the type of P_160E60E movable sidewall cover wagon side wall cover wagon in China are analyzed.By analyzing the existing technical parameters and basic characteristics of China's existing locomotives,EMUs,package?mail?vehicles and trucks,it is concluded that the relevant technology accumulation for the development speed of 160 km/h rapid wagons and the type of P_160E60E movable sidewall cover wagon side wall cover wagon in China has met the requirements.And then,by using running rapid cover wagon,improving the transportation efficiency of goods and shorten the transportation time as starting point,the main technical parameters and usage of various parts are compared in detail,and the main process of selecting the technical parameters of the type of P_160E60E movable sidewall cover wagon side wall cover wagon is expounded.Then based on the actual situation of domestic express transport and combined with the basic status quo of the development of domestic and foreign fast trucks,the final technical proposal was put forward for the overall idea and design goal of the P_160E60E type activity side wall cover wagon.Then based on the actual situation of domestic express transport,considering the development status of domestic and foreign express transport,the final technical proposal for the general idea and design goal of the type of P_160E60E movable sidewall cover wagon side wall cover wagon was put forward.Finally,based on the TB/T1335-1996 standard,the stiffness and strength assessment conditions of the type of P_160E60E movable sidewall cover wagon side wall cover wagon are put forward,and the fatigue assessment conditions are put forward based on the standard of AARM-1001 2011,and the static strength analysis and fatigue analysis of the type of P_160E60E movable sidewall cover wagon side wall cover wagon are carried out by finite element analysis.Based on the TB/T1335-1996standard,the prototype of the type of P_160E60E movable sidewall cover wagon side wall cover wagon was tested for stiffness and strength,and all the development work of the type of P_160E60E movable sidewall cover wagon side wall cover wagon is completed in the end.At the end of this paper,the technical and economic comparison of the type of P_160E60E movable sidewall cover wagon side wall cover wagon and the existing cover wagon is made.It is concluded that the use of the type of P_160E60E movable sidewall cover wagon side wall cover wagon can reduce user's transportation cost,shorten the time for transportation,accelerate vehicle circulating availability,improve the utilization efficiency of the locomotive and vehicle,and realize the expansion of the railway transportation capacity.The development of the type of P_160E60E movable sidewall cover wagon side wall cover wagon provides a reference for the development of China's rapid railway freight transport and is conducive to the further development of rapid railway freight transport equipment in the future.
