摘　　要：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.This paper is a further study of the tuned-rotary-inertia-damper（TRID） system based on the previous work of modeling of TRID system and the work of small-scale model experiments. First, the full-scale pendular vibration control experiment of a medium crane hook is carried out to verify the effectiveness of the TRID control system. Next, a TRID system is designed to control the pendular vibration of the crane hook on a large ship sailing in the ocean. As the TRID system is too large to be used in practical engineering, the gear box is introduced to miniaturize the TRID system. Through a preliminary miniaturization study and the numerical analyses, we find that the gear box is desirable for generating a large-equivalent rotational inertia for the small physical inertia in the TRID system.
