摘要
针对CRH3型动车组跨接电缆的车端安装接口,探讨了使用悬链线方程计算电缆长度的可行性及必要约束条件,将MATLAB软件的计算结果与CRH3型车的实际跨接电缆长度进行了比较,证明了计算方法的可行性和计算结果的准确性。
In view of the car end installation interface for the jumper cable on CRH3 multiple units,the feasibility to use the catenary equation to calculate the length of cable as well as the necessary constraint conditions is discussed.The calculation result of the MATLAB software is compared with the actual length of the jumper cable on CRH3 multiple units.The feasibility of the calculation method and the accuracy of the calculation result are proved.
