地铁转向架排障器的结构改进及疲劳性能评估
Published 2021-01-01“…In view of the fracture and edge crack initiation of the bogie cowcatcher during the service of a metro train,the failure causes are analyzed,and a fatigue performance evaluation method combining finite element analysis and dynamic stress test is proposed to verify the rationality of improving the structural design of the cowcatcher.Firstly,the structure of the cowcatcher with fracture or edge crack is analyzed in the aspects of design,structure,manufacturing and raw materials,and the corresponding structural improvement scheme is proposed.Secondly,the static strength and fatigue strength of the structure for the new cowcatcher are analyzed to clarify the dangerous parts according to the EN13749 standard.Thirdly,determine the strain gauge layout plan and conduct line tests considering the simulation analysis results and the operating space comprehensively.Finally,the fatigue performance evaluation of the cowcatcher is carried out by miner’s linear cumulative damage rule and IIW recommended S-N curve.The results show that the fatigue performance of the new type of cowcatcher based on finite element analysis and dynamic stress test meet the requirements,and the two support each other to further verify the rationality of the new structure design.Simultaneously,the simulation analysis results provide a theoretical reference for the reasonable arrangement of measuring points.…”

OUTSIDE REARVIEW MIRROR PANORAMIC CAMERA POSITION ON THE AERODYNAMIC CHARACTERISTICS OF IMPACT STUDY
Published 2018-01-01“…In order to reduce the influence of the panorama camera on the aerodynamic noise of the vehicle,the exterior flow field and sound field analysis are carried out on the rearview mirror of three different lens placement positions.The calculated results are in good agreement with the experimental data,which verifies the reliability of the numerical simulation.At the same time,it is found that the different position of the panoramic lens has an influence on the air flow which through the exterior mirrors,thus changing the rear flow field and the front window noise radiation intensity.Scheme Ⅲ is compared with other schemes,the tail vortex,the turbulence kinetic energy and the noise emission of the front window are relatively weaker,which can reduce the aerodynamic noise.Finally,by comparing the noise test of three kinds of schemes,it is found that the noise of scheme Ⅲ is lower than that of other schemes,which verifies the correctness of the analysis method.The analysis results provides the guidance for the reasonable arrangement of the rearview mirror panorama image lens,and is favorable for improving the comfort of the driver.…”
