Setting of Transition Section of Spring-steel Floating Slab Track on Guiyang Rail Transit Line 1
摘要
Abstract
The big difference of stiffness between the short sleeper monolithic track bed and the spring-steel floating slab track foundation calls for a transition section for smooth transition of the stiffness under the rail. The author, based on the short sleeper monolithic track bed and the spring-steel floating slab track that are widely used in Guiyang rail transit line 1 , sets up a mechanics model of transition section between the short sleeper monolithic track bed and the spring-steel floating slab track. This paper analyzes the influence of different length, classification and speed on the transition section with the finite-element method. At the same time, the pattern of transition section with encryption steel spring bearing in combination with fasteners on the side of sleeper monolithic track bed is also analyzed. The results show that different length and classification have different impact on the performance of the transition section. The pattern of transition section of encryption steel spring in combination with fasteners is better than that of only encryption steel spring.关键词
