摘要
文中针对地面雷达的结构特性,对地面雷达铁路运输过程中的受力进行了简要的分析。按《铁路货物装载加固规则》要求设计了加固方案,并对易出错参数的选取进行了解释和规范。在风力计算中考虑了货车交会时产生的附加风压。分析比较了因平板车上捆绑点位置不同引起的拉牵绳纵(横)向拉力数值变化对加固强度的影响,提出了计算公式的修正方法,有利于铁路提速后的运输安全,具有一定的参考价值。
Based on the structural characteristics of the ground-based radar,a brief mechanics analysis of the ground-based radar during railroad transportation is carried out in this paper.According to Railroad Cargo Loading and Reinforcement Rules,a reinforcement project is designed and the selection of the error-prone parameters is explained and standardized.In wind resistance calculation,the additional pressure caused when two trucks meet is considered,then the effect on reinforcement of the vertical and transverse tensile value change caused by the different binding site selection is analyzed and compared.After that,a method is proposed to amend the formula.This result shows that the method can improve the speed-up railroad transportation safety and can provide a reference for engineering.
