摘　　要：分析了定心上摆式递纸机构的运动过程,建立了机构的动力学模型。该模型为一存在弹性变形的四杆机构,运用Lagrange方程建立了该模型的动力学运动方程,通过摄动分析对模型进行了求解,得到了与实际运行相一致的结论。分析表明,弹性连杆机构动力学系统中存在内共振和组合共振,运动副间隙、机构边界条件、阻尼和机构尺度均可能引起机构产生非线性振动,而机构弹性构件的变形是导致机构产生非线性振动的关键因素。The uncertainty resources constraint project scheduling problems （URCPSP） is the hot spot in the present study. The task scheduling with the processing time to be an interval number belongs to the URCPS＇P （uncertainty resources constraint project scheduling problems）. Aimed at the uncertain scheduling of fine-graded collaborative designing task in the virtual enterprises this paper established its model and let it be transformed into certainty plan by adopting the ＂possibility level＂ method, and carried through the soiution by means of genetic algorithm （GA）. The structure of this genetic algorithm was presented in this paper and the concrete operational method of coding of ＂chromosome to be sub sectioned according to resources, and to be arrayed according to the task order within the section＂ was put forward. The concrete realization of this uncertain scheduling was explained in this paper by a living example, and analysis showed that this method possesses pretty good values of reference.
