Analysis of Performance and Frequency Response Characteristics of Fasteners for High-speed Railway
摘要
Abstract
The performance and frequency response characteristics of the fastener clips in high-speed railway are analyzed. With the clips of fastener SKL15 as the object, the finite element model of the fastener system is established by means of Solidworks software and ABAQUS code. The modal frequencies of the fastener in the free state and assembling state are analyzed respectively, and the modal frequencies of the same mode are obtained, which are 297 Hz, 440 Hz, 758 Hz, 1 292 Hz and 363 Hz, 632 Hz, 1 233 Hz, 1 645 Hz for the two states. The performance parameters analysis of the fastener under different torques is also carried out. The relationship between the projectile range of the clip and the buckle pressure of the fastener under the normal installation conditions is obtained. In order to further analyze the performance of the fastener clips, the frequency response of the track structure is tested in a high-speed railway section. The peak frequency of the fastener is 620 Hz according to the test, which is close to the assembling modal frequency of 632 Hz. Thus, resonance of the fastener system may occur, which can cause the fatigue failure of the fastener.关键词
