摘　　要：应用调谐质量阻尼器(tuned mass damper, TMD)改善某摩托车手把振动。建立了用于手把减振研究的整车有限元模型,通过振动台架试验验证发动机激励下所建模型的可行性。提出了一种符合TMD安装方式的嵌入式TMD振动模型,以手把第一阶振动模态频率为TMD调谐频率,以抑制手把振动加速度响应为目标,结合Den Hartog定点理论和等价质量识别法确定了嵌入式TMD最优减振设计参数值。通过发动机激励下的手把振动响应分析表明:所设计TMD对手把振动有显著抑制效果,其总加权加速度均方根值减小了37.8%。A tuned mass damper(TMD) is applied to improve handlebar vibration of a motorcycle. A motorcycle finite element model is established for the study of handlebar vibration reduction, and the feasibility of the model under engine excitation is verified by vibration bench tests. An embedded TMD vibration model is proposed in accordance with the actual TMD installation mode. Taking the first order vibration mode frequency of the handlebar as TMD tuning frequency and aiming at suppressing the vibration acceleration response of the handlebar, this paper combines Den Hartog fixed-point theory and equivalent mass identification method to determine the optimal vibration damping design parameters of the embedded TMD. The vibration response analysis of the handlebar under engine excitation shows that the designed TMD has a significant suppression effect on handlebar vibration, and the root-mean-square value of its total weighted acceleration decreases by 37.8%.
