摊铺机振捣机构工作时，振捣梁的复合运动会对熨平板箱体产生冲击，直接影响了路面的摊铺质量。以9.0m熨平板双振捣机构为研究对象，采用多体机械系统仿真软件ADAMS建立了熨平板振捣器的动力学模型，通过仿真分析，得到了振捣频率、振幅及各段间相位角对振捣梁惯性力和惯性力矩的影响规律。结果表明：主振捣振幅为5mm，副振捣振幅调整为3或6mm时，振捣器产生的惯性力和惯性力矩较小；随着振捣转速的增加，振捣装置的惯性力增加幅度较大，且均匀性变差；各加长段间的相位角调整为60°时，双振捣机构对熨平板框架产生的影响较小。
Abstract
When the tamper mechanism of paver is working, the composite motion of the beam will have an impact on the screed. The virtual prototype model of 9.0m double-tamper mechanism is established and simulated by the simulation software-ADAMS .The impact regularity of the vibrating beam inertia force and moment of inertia as a result of the vibration frequency , vibration amplitude and phase relationships is obtained. The result of analysis shows that the inertia force of the vibrating beams increases greatly with the vibration speed increasing, and the uniformity gets worse. It has a little effect on the frame of flatiron-box when we take the phase angle as 60° in practice.
