结构静力分析是动力分析的基础。在计算接头处轮轨冲击力时需要用到接头的静力折角及接头处的轨道刚度值。为此,首先需要计算鱼尾板所承受的弯矩。本文主要有以下成果: 1.在文献[1]的基础上,整理推导了轮群荷载作用下计算鱼尾板弯矩的通式,使之更便于理解和掌握; 2.计算了轨端折角,算例中得出的折角为41×10~(-3)弧度,而文献[3]22页给出的实验值是4.5×10~(-3)弧度;
Structural static analysis is the basis of dynamic analysis. When calculating the wheel and rail impact at joint, it is necessary to use the static bending angle of the joint and the rail stiffness value at the joint. To do this, we first need to calculate the bending moment of the fish plate. The main contributions of this dissertation are summarized as follows: 1. Based on the literature [1], the formula for calculating the bending moment of fish plate under wheel load is derived and complied to make it easier to understand and master. , The bending angle obtained in the example is 41 × 10 ~ (-3) radian, while the experimental value given in [3], page 22 is 4.5 × 10 ~ (-3) radian.
