Design of a Certian Electric Train Door Frame Based on Carbon Fiber
Through the static analysis of a type of rail door frame door column,door upper crossbeam,door corner structure,this paper determines that the maximum Von-Mises stress at each place of the door frame structure under four load conditions are less than the allowable value.In this design,the door frame structure will be designed with T700 carbon fiber equivalent and loaded with four working conditions,and the stress levels at all parts of the equivalent design structure meet the specification.Then the free size optimization,dimensional optimization and cladding sequence optimization are carried out for the composite door frame,and finally the actual cladding scheme of T700 is obtained.The new structure is more than 35%lighter than the original metal door frame structure,and the weight reduction effect is extremely obvious.The design provides a reference for the subsequent car body change to use carbon fiber composite parts.
