| 中文摘要: |
| 提出一种集成曲柄连杆机构、齿轮增速系统、单向轴承、飞轮储能模块及永磁同步发电机的新型曲柄连杆式馈能悬架（Crank Train Shock Absorb，CTSA），该装置通过机械传动和机电转换实现悬架振动能量回收。推导出CTSA惯容系数解析表达式，建立了含CTSA的车辆动力学模型，应用遗传算法对参数进行优化，利用飞轮转速补偿降低了随机振动导致的转速波动。结果表明：优化后的CTSA相较于传统悬架能够降低车辆共振频率至人体敏感频率范围（4～12.5Hz）外，同时使悬架动挠度共振峰值降低19.58%；当车辆以60km/h速度在B级路面上行驶时，CTSA能量回收平均功率为43.53 W。 |

| A novel Crank Train Shock Absorb（CTSA）integrating a crank train mechanism, a gear speed-increasing system, one-way bearings, a flywheel energy storage module, and a permanent magnet synchronous generator is proposed in this paper. The device achieves suspension vibration energy recovery through mechanical transmission and electromechanical conversion. The analytical expression for the inerter coefficient is derived, and a vehicle dynamics model incorporating the CTSA is established. A multi-objective Parameters are optimized using a genetic algorithm, and flywheel speed compensation is applied to mitigate rotational speed fluctuations caused by random vibrations. Results indicate that the optimized CTSA, compared to a conventional suspension, shifts the vehicle resonance frequency outside the human sensitive frequency range (4～12.5 Hz), reduces the suspension dynamic deflection resonance peak by 19.58%,and when the vehicle travels at 60 km/h on a B-class road, the CTSA achieves an average energy recovery power of 43.53 W. |
