Abstract：Research purposes: The improvement and optimum are made for the structure of slide bar of speed-increase turnout for the purpose of solving the existing problems of it, such as failure of tightening force, cracks in spring shim and pin, large surface resistance of slide bed-plate, difficulty in gauge adjusting and so on.
Research conclusions: On the one hand, the improved slide bar can consistently and reliably pressure the inner side of stock rail to keep the consistent pressure. On the other hand, it can be easily and flexibly adaptable to gauge adjustment of stock rail. In addition, the slide bar can reduce the switching resistance of turnout and insufficient displacement of switch rail to guarantee the reliable switching of turnout, which meets the requirement of railway for slide bar.
