The invention discloses an annular time-delay feedback control dynamic vibration absorber for a vehicle, and aims to provide a wheel vibration energy absorbing device which is wide in working frequency band, capable of adjusting inherent frequency in real time, simple in structure and convenient to install. The dynamic vibration absorber comprises a spring, a damper, a time delay controllable actuator, an annular energy absorption mass block, a displacement sensor and an electric control unit. According to the annular time-delay feedback control dynamic vibration absorber structure for the vehicle, when a wheel is excited by a road surface to generate vibration, the inherent frequency of the annular time-lag feedback control dynamic vibration absorber can be changed to be equal to the vibration frequency of the wheel, vibration energy of the wheel is absorbed to the annular energy absorption mass block, vibration of the wheel is effectively reduced, and wheel vibration energy transmitted to a vehicle body is reduced, so that the operation stability and the running smoothness of the vehicle can be improved.
本发明公开了一种车用环形时滞反馈控制动力吸振器,旨在提供一种工作频带宽、可实时调节固有频率、结构简单、安装方便的车轮振动能量吸收装置。它包括由弹簧、阻尼器、时滞可控作动器、环形吸能质量块、位移传感器、电控单元组成。本发明设计的车用环形时滞反馈控制动力吸振器结构,可在车轮受到路面激励产生振动时,改变环形时滞反馈控制动力吸振器自的固有频率使之与车轮振动频率相等,将车轮的振动能量吸收到环形吸能质量块上,有效减小车轮振动,并减少了车轮振动能量传递到车身,可提高车辆的操纵稳定性和行驶平顺性。
