Analysis On Stability Of CWR With The New Type Wheel Protection Railroad Rail Facility On Minor Radius Curve

As a new type of track structure, because of its comfort, smooth, low maintenance cost advantages, CWR provide a strong technical support for railway developing in the high-speed, heavy-haul transportation direction. How to prevent small radius curves CWR buckling accidents, to maintain the stability of CWR, to ensure traffic safety, which is a vital topic. Relevant operating experience shows that the new type off-rail prevention, wear-resistant and wheel protection railroad rail facility can strengthen the track structure to improve the stability of CWR. The new type wheel protection railroad rail facility has a broad application prospects. Studying the stability of radius curve CWR which is installed the new type wheel protection railroad rail facility has important theoretical and practical significance.Aim at the CWR which is installed the new type wheel protection railroad rail facility, stability analysis model is established to calculate the CWR stability which is installed the new type wheel protection railroad rail facility, using MATLAB language. Study the effects of the new type wheel protection railroad rail facility in improving the stability of CWR. The main contents are as follows:1. Aiming at the defect of the formula which based on the law of equilibrium of inner and external moment of force, Re-establish the stability formula of the CWR, and compare unconnected and corrected formulas with the improved uniform formula. Calculate the small radius curves CWR stability which is installed the new type wheel protection railroad rail facility, using MATLAB language.2. Calculate the state-owned railways, local railways, urban rail, special railways CWR stability in the case whether CWR is installed the new type wheel protection railroad rail facility. Through comparative analysis, it can be seen, the new type wheel protection railroad rail facility can effectively enhance the stiffness of the track frame, to effectively improve the stability of the CWR.3. Local railway small radius curves CWR for instance, study the impact parameters of the small radius curves CWR stability by calculating, and draw the law of impact on CWR stability. Investigate the possibility of laying CWR in smaller radius curves.4. Explore measures to improve the stability of CWR by calculating.
