摘　　要：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.采用多体机械系统仿真软件ADAMS,建立了振捣机构的动力学模型,通过对振捣机构的仿真分析,得到了振捣频率和振幅对振捣梁惯性力和惯性力矩的影响规律.结果表明,在满足路面压实度的条件下,应尽量采用低频振捣,且主副振捣机构的相位角应选择150°.Owing to the tamping mechanism of paving machines, the shocks towards flatiron-box are produced by compound motion of tamping beam. This significantly influences the road paving quality. Based on the simulation software for multi-body mechanical systems, i.e. ADAMSTM, a dynamical model is established for tamping mechanism. In particular, the correlation between tamping frequency-amplitude and tamping-beam inertia force-moment is detected. In order to satisfy the road compactness, the low-frequency tamping is preferred with a phase angle of 150° between master and slave tamping mechanisms.
