| 標(biāo)題 |
| 組合式制動梁易產(chǎn)生裂紋的問題分析及采取的對策(35 卷) |
| 英文標(biāo)題 |
| Analyzing the Cracks Frequently Happened in Combined Brake Beam and the Countermeasures |
| 摘要 |
| 通過對一起因制動梁架圓弧修磨不圓滑而致使L-B型組合式制動梁動載荷試驗(yàn)出現(xiàn)裂紋的事例分析，表明在制動梁架生產(chǎn)過程中存在不規(guī)范的操作，導(dǎo)致修磨圓弧出現(xiàn)棱角，產(chǎn)生局部應(yīng)力集中，并使制動梁在動載荷試驗(yàn)中的交變載荷作用下開裂。 |
