摘要: 为提高摩托车在较差路况下的减震效率,增加行驶的平稳性和乘坐人员的舒适性,设计研究了一种混合式智能减震系统.该系统以弹簧、电磁铁为基础,空气阻尼为耗损振动能介质,利用压力传感器实时检测振动力的变换,自动调节电磁作用力,使系统具有自适应调整减震的能力.通过ANSYS对系统电磁部分进行性能仿真,分析该系统的力学性能和电磁性能,并阐述了系统设计方案.仿真分析表明,在相同载荷和冲击力条件下,混合式智能减震系统与一般筒式液压减震系统相比,不仅减震性能好,同时具备自动化柔性减震功能,能够满足较差路况的减震需求,使摩托车行驶更加平稳.能耗分析表明,在连续振动冲击下,使用7Ah蓄电池给系统供电,系统能够有效工作5.4h,完全能够满足实际使用需要.Abstract: A hybrid intelligent shock absorption system that uses spring and electromagnet as the basis and air damping as the vibration loss medium is designed to improve the shock absorption efficiency under poor road conditions and to increase smooth driving and riding comfort .A pressure sensor is used to realize a re‐al‐time test of vibration change and automatically regulate the electromagnetic force to get a self‐adapting shock absorbing system .The electromagnetics performance of the system is simulated through ANSYS to analyze its mechanical property and electromagnetic performance and to expound the system design scheme .The simulation analysis indicates that with the same load and impact ,the hybrid intelligent shock absorption system shows better performance and excellences than the commonly used cylindrical hydraulic shock absorbers ,and it has automatic flexible shock absorption to meet the need of smooth driving under poor road conditions .The energy consumption analysis indicates that this system can work effectively for 11 h under a continual vibration condition with a 7Ah battery ,which can meet the needs of practical use .
