基于前期研究工作建立了调谐转动惯量阻尼器(tuned rotational inertia damper,TRID)理论模型并进行数值分析和小比例模型试验,首先对一台中型桥式起重机的吊钩进行了摆振控制的足尺模型试验,进一步验证了TRID系统控制悬吊结构摆动的有效性.其次针对某大型海洋起重铺管船浪涌致吊钩摆动问题设计了TRID控制系统.然后针对在大型工程实际应用中TRID系统需要较大转动惯量的问题,提出了通过引入变速器使TRID系统小型化的方案,并对该方案进行了理论分析和数值模拟验证,结果表明,通过引入变速装置,TRID系统可以采用较小的实际转动惯量来获得等效的大转动惯量,从而可以使TRID系统实现小型化.
Based on the previous work, a theoretical model of tuned rotational inertia damper (TRID) was established, and numerical analysis and small-scale model tests were carried out. Firstly, the full scale control of a mid-sized overhead crane hook Model test to further verify the effectiveness of TRID system to control the swing of the suspended structure.Secondly, a TRID control system is designed for the swinging of the hook of a large marine crane pipelaying ship surge.Then, for the practical application of the TRID system Which requires a large moment of inertia, proposes a scheme of miniaturization of TRID system by introducing a transmission, and carries out theoretical analysis and numerical simulation verification of the scheme. The results show that the TRID system can adopt a smaller practical Moment of inertia to obtain the equivalent large moment of inertia, which can make the TRID system to achieve miniaturization.
