摘要: 力隔振试验系统是力隔振研究中最基本和必需的装备,从机理和传感器设置等方面都有别于现有的振动台。针对半主动力隔振研究的要求,研制了适用于单、双层力隔振控制的试验台和测量系统。设计并建立基于同步振动原理的机械机构和传感器体系;推导双电动机同步振动激励力的数学表达式;确定力传递率的测量理论和方法,并构建基于PC的传递率测量的软、硬件系统;分别测量单、双层力隔振试验台的无阻尼传递率,以及应用Lord公司RD-1005-3磁流变阻尼器后的小阻尼力和大阻尼力条件下的力传递率。试验结果表明,力隔振试验台的无阻尼传递率与理论传递率相吻合,而由于磁流变阻尼器的强非线性,小阻尼力和大阻尼力传递率和理论值相比具有明显的特异性。

Abstract: Experiment system is essential to the investigation of force isolation, which is much different from the exciter for displacement isolation upon mechanism and transducer setting. A rig and corresponding measuring system is developed to ful-fill the requirements of the force isolation of single layer or double-layer system. First, framework based on synchronized dual rotational vibrators is designed and made. Secondly, the exciting force of the exciter is deduced. Thirdly, measuring method, PC based software and hardware for force transmissi-bility is presented. Finally, force transmissibility of the double- layer and double-layer systems of no damping, light damping and heavy damping provided by Lord Company produced MR damper RD-1005-3 is measured independently. The results show that the experimental damping free transmissibility matches well the theoretical one; however, the experimental transmissibility of light damping and heavy damping differs much from the theoretical one because of the strong nonlinear-ity of the MR damper.
