摘　　要：针对SS4B直流电力机车砂管支架断裂故障进行了详细的调查,分析确定了老型砂管支架断裂故障的根本原因,制定了有效的优化方案,并对改进方案进行了相关的试验验证及仿真分析,最终装车试验效果良好。新型砂管支架采用304不锈钢材质并对结构进行优化,解决了老式砂管支架的安装问题。新型砂管支架极限拉伸强度较老式砂管支架提升,相对变形量也低于老式砂管支架,优化后的砂管支架不易产生断裂等问题。新型砂管支架性能强度整体增强,减少了机车砂管支架断裂的隐患,达到了预期效果,保障了机车的高效安全运行。Based on the detailed investigation for sand pipe bracket fracture fault of SS4B DC electric loco⁃motive,this paper analyzes and locates the root cause of the old sand pipe bracket fracture fault,develops an effective optimization scheme,and conducts the test verification and simulation analysis for the improve⁃ment scheme,ultimately leading to a good loading test effect.The new sand pipe bracket is made of 304 stainless steel and its structure is improved to resolve the installation issue of the old sand pipe bracket.The ultimate tensile strength of new sand pipe bracket is improved compared with the old sand pipe bracket,and the relative deformation is lower than that of the old sand pipe bracket.The improved sand pipe bracket is not prone to fracture or other problems.For the new sand pipe bracket,the overall performance and strength are enhanced,the potential risk of fracture of the locomotive sand pipe bracket is reduced,indicat⁃ing that the expected effect is achieved.This supports the efficient and safe operation of the locomotive.
