摘要:
 对比分析了现有高速动车组设备舱强度计算与评估标准,提出将气动载荷设为定值研究设备舱疲劳强度的方法。通过静强度分析优化改进了设备舱结构,对比分析了单独施加气动和冲击,同时施加气动和冲击对设备舱静载荷的性能影响;同时参照标准和实测载荷,探索性研究了不同气动载荷下设备舱疲劳特性。分析结果表明,气动载荷对设备舱强度影响较大,±1 500 Pa 气动载荷下设备舱疲劳强度满足设计要求。
Abstract:
 By comparing and analyzing the existing strength calculation and evaluation criteria of equipment cabin of high-speed EMUs, the method of setting aerodynamic load as fixed value to study the fatigue strength of equipment compartment was put forward. Through static strength analysis and optimization, the structure of equipment cabin was improved, and the effects of pneumatic and impact separately and simultaneously on the static load performance of equipment cabin were compared and analyzed. At the same time, the fatigue characteristics of equipment cabin under different aerodynamic loads were explored according to the standard and measured loads. The analysis results show that the aerodynamic load has a great influence on the strength of the equipment cabin, and the fatigue strength of the equipment cabin meets the design requirements under (±1 500 Pa) aerodynamic load.
