Backlash cannot be always avoided in mechanical systems because of wear or looseness. Steady-state vibration may be induced by backlash in closed loop feed drive systems. This paper presents a mathematical model of a servo rotary table, considering the effect of backlash. The accuracy of this model is verified by an experiment. The influences of the parameters, such as position controller gain, velocity controller gain, load and the magnitude of backlash, on steady-state vibration are discussed. The steady-state vibration amplitude increases with the position controller gain, load and the magnitude of backlash. The steady-state vibration frequency increases with the position controller gain and the velocity controller gain, while an increase in load leads to a decrease in the frequency.

以我国30年大跨度桥梁的快速发展为研究背景,对3种大跨度桥梁的抗风技术挑战进行了基础性研究和应用性研究,着重探讨了悬索桥的颤振性能及其控制、斜拉桥风振性能与拉索风雨振控制、拱式桥涡激共振及其控制、特大桥梁风振精细化理论等一系列抗风关键问题。研究结果表明:悬索桥的颤振稳定性跨径上限约为1 500 m,超过甚至接近这一上限时,必须采取措施改善加劲梁的抗风稳定性;千米级大跨度斜拉桥仍具有足够高的颤振临界风速,其主要抗风问题是长拉索的风雨振动;大跨径拱桥除了个别有涡振问题之外,还没有受到结构抗风性能的影响。文章还提出了三维桥梁颤振精确分析的全模态方法、任意斜风作用下桥梁抖振频域分析方法、基于二阶矩理论和首次超越理论的桥梁颤振和抖振可靠性评价方法,揭示了桥梁颤振演化规律、驱动机理和控制原理。

提出了一个预测潜在冲击载荷下振动效应的理论模型与现场实测相结合的综合预测方法。通过一系列具有针对性的室外重锤冲击振动试验,以及现场实测数据对Anderson 模型进行了验证并修正,然后利用修正的Anderson 模型预测冲击荷载的振动效应。将预测结果和现场试验结果进行对比分析,结果表明:预测结果与实测结果吻合较好。
