摘要
制作一个钢质锥柱形平头旋转壳体,使用中国船舶科学研究中心的冲击水池,采用自由落体投放,拖长线测量方法,测定撞水压力、撞水加速度及撞水应变.由测值得出乎头旋转体入水的峰压与初速成正比关系,P=1.016+1.139υο,并实测出体现水弹性各参量关系的时程曲线.
An axisymmetric flat blunt conical made of steel is designed as a free dropping testing model. Method of long towing cable is used to determine of impact. A linear relation between maximum pressure and entering velocity, P=1.016+1.139v_o is found experimentally for such a model. The graphical relations between various hydroelastic parameters and time are also included.
