【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]:In order to improve the vibration absorption efficiency of motorcycles in poor road conditions and increase the ride stability and comfort of passengers, a hybrid intelligent shock absorption system is designed and studied. The system is based on springs and electromagnets. Air damping is an energy dissipation medium. The pressure sensor is used to detect the change of vibration force in real time, and the electromagnetic force is automatically adjusted. The system has the ability to adjust and absorb the vibration adaptively. The mechanical and electromagnetic properties of the system are analyzed by the simulation of the electromagnetic part of the system by ANSYS. The simulation results show that, under the same load and impact force, the hybrid intelligent damping system is not only better than the conventional cylinder type hydraulic shock absorber system. At the same time, it has the function of automatic flexible shock absorption, which can meet the needs of poor road conditions and make the motorcycle running more smoothly. The energy consumption analysis shows that 7Ah battery is used to power the system under the impact of continuous vibration. The system can work 5.4hs effectively and can meet the practical needs.
