摘　　要：针对矿砂船质量分布的特点,研究矿砂船横摇转动半径的估算方法,通过3型矿砂船的对比,分析矿砂船横摇转动半径的特点,针对大型矿砂船不同的装载工况给出一种横摇转动半径的估算公式。以某型矿砂船为例,通过对比分析研究横摇转动半径估算值对载荷和结构应力的影响。研究表明该估算公式是合理的。Aiming at the features of mass distribution of VLOC, the estimation method for roll gyration radius of VLOC is studied. By the comparison of three ore carriers, the characteristics of the roll gyration radius of VLOC are analyzed. An estimation formula of roll gyration radius is given for different loading conditions of VLOC. VLOC is taken as an example to compare, analyze and study the influence of the roll gyration radius estimation on the loadings and structural stress. It is shown that estimation formula is reasonable.
