摘　　要：印刷机串墨机构的载荷分布特性是对墙板进行有限元分析的基础。利用动态静力分析法,建立了串墨机构运动副间动载荷的数学模型;用消元法得到了各运动副反力的解析式。结合实例分析了机构的动载荷分布特征。研究表明:各运动副反力和反力矩在换向位置均出现突变,引起墙板的振动,从而造成印刷故障。Distribution characteristic of dynamic forces and moments for the oscillating ink mechanism of press is the fundamental of Finite Element Analy sis (FEA) to the wall of the press. Based on the kinetostatic method, the dynami cload model to the motion pairs of the oscillating ink mechanism isderived. Fur thermore, the analytical formula of force and moment is given by elimination method. The dynamic load's feature between the motion pairs of the mechanism is analyzed with examples. It is shown that sudden change of the forces and moments between motion pairs takes place at the position changing direction of the oscillation roller, leading to the shock and vibration of the wall and printing troubles.
