摘要
采用有限元分析的方法,建立了计算简支梁桥上无缝道岔温度力与位移的有限元力学模型。计算了桥上无缝道岔的受力与变形,并分析了桥梁结构对无缝道岔的影响。研究结果对桥上无缝道岔的设计有一定的指导意义。
A finite element mechanics model to calculate the temperature force and displacement of the joiless switch on simple supported beam bridge by using the finite element method. The forces and displacement ofjoiless switch are computed, and the influences on seamless turnout of bridge structure are analyzed. The results could be used to guide the design of joiless switch on bridge.
