摘要:
［目的］与轴箱外侧悬挂转向架相比，内置式转向架具有质量小、通过曲线能力强、轮轨磨耗小、噪声低的特点，但内置转向架的一系抗侧滚能力不足，横向尺寸非常小，零部件布置空间狭小，适应速度等级低，在高速动车组上应用较少。对此，有必要对高速动车组内置式转向架的设计与试验验证进行研究。［方法］以开发新一代高速动车组转向架为背景，设计了以复合材料板弹簧技术和油气悬挂装置作为一系悬挂装置的新型400 km/h高速动车组内置式转向架，采用ANSYS等软件进行了主要部件的强度仿真分析，采用SIMPACK多体动力学软件对转向架进行了动力学仿真计算，并开展了主要部件的疲劳试验、转向架试验台滚振试验及整车线路试验测试。［结果及结论］计算结果及试验结果表明：强度、动力学各项技术指标均符合相关标准要求，其中试验台试验速度达到了606 km/h。
Abstracts:
［Objective］ Compared with bogies suspended on the outer side of the axle box, built-in bogies offer advantages such as light weight, superior curve negotiation capability, lower wheel-rail wear and noise. However, built-in bogies typically suffer from insufficient primary lateral anti-rolling capability, very compact lateral dimensions, limited space for component arrangement, and lower adaptability to high-speed applications, making their use in high-speed EMUs (electric multiple units) relatively uncommon. In response, it is necessary to carry out research on the design and experimental verification of high-speed EMU built-in bogies. ［Method］ In the context of developing a new generation of high-speed EMU bogies, a new type of built-in bogie for 400 km/h high-speed EMUs is designed, utilizing composite plate spring technology and oil-gas suspension devices as primary suspension system. Strength simulation and analysis of major components are conducted using ANSYS and other software tools. SIMPACK multi-body dynamics software is used to perform dynamics simulation calculation of bogies. Fatigue tests of key components, rolling vibration tests on the bogie test bench, and full-vehicle track tests are also carried out. ［Result & Conclusion］ The calculation and test results indicate that various technical indicators such as strength and dynamics performance all meet the requirements of relevant standards. Notably, the test bench trials achieved a speed of 606 km/h.
