Research on the "Elastic Putting Putting Panel of Hermore Railway Micro -Pole Railway Railway" formed by the research project "Research on the Research of the Research Railway Technology Upgrade" of the National Railway Group "Elastic Panel"。

　　For the Daqin heavy 188bet mobileload railway freight trains, the impact of the line is large，Rail geometry is difficult to maintain，Dao bedboard is serious，The elasticity of the rail structure is largely relying on the undercate pads and other conditions，On the basis of absorbing and learning from related research at home and abroad，Analysis of the application scenario of elastic pads under the track、material selection、Structure optimization design、Disposal analysis、Movement friction analysis, etc., conducted comprehensive 188bet loginresearch，The design of the elastic 188bet loginpads under the micro -hole polyurethane of the heavy -daising railway。

　　The main technical innovation of the research results:One isA three -dimensional mesh structure macromolecular polymer prepared by a reasonable chain -length polyether polyol and isocyanate，Optimization of the combination of soft sections and hard segments，To the best degree of micro -phase separation，Make the pad board have a good return elasticity、weather resistance and stability stability。The second isMicro -hole polyurethane 188bet sports bettingtablet structure improves the 188betrelationship between elastic layer and concrete pillow，Reduced damage to concrete pillows，Improved service performance。

　　Elastic pad，Use polyurethane stereo mesh molecular structure to follow a certain cross -linking density，Get excellent material back elasticity、weather resistance and stiffness stability，Effectively improved the service cycle of the pads under the volume of heavy -duty railways，Reduced the rail wave grinding caused by the loss of elasticity of the pads、Loose of fasteners、Dispellet deviation and 188bet mobileother diseases generate risks，Provided 188bet mobiletechnical support for operational safety。The tablet structure design it adopted，Use the micro -hole deformation of the material to provide support，increased the contact area of ​​the pad and the pillow，Effectively alleviated the problem of wear and cutting slot of the pillow bearing surface，Improving the service life，Reduced pillow wear，Effectively reduced the frequency of the padding board to change the frequency，Save the cost of the pillow replacement，Improved transportation 188bet sports bettingefficiency，Have good technical and 188beteconomic benefits and promotion and application prospects。
