摘要
防波堤护面块体是防波堤上抵御波浪冲击的重要构件,受波浪冲击时会发生摇摆甚至造成破坏。采用IMU惯性传感器测量护面块体受波浪作用规律。根据惯性导航系统中坐标系转换原理,将IMU惯性传感器安放在护面块体上并放置在3种不同水线位置上进行试验,对IMU惯性传感器获取的角速度信号进行处理得到冲击速度、碰撞数。试验结果表明,在水线z/D_(n)=-2处的碰撞数要比在水线z/D_(n)=0和z/D_(n)=2要大,最大冲击速度发生在水线z/D_(n)=0处。通过以上测量参数可为块体防护提供定量评价。
The block of breakwater protection surface is an important component of breakwater to resist wave impact.The angular velocity signal obtained by IMU inertial sensor was processed to an IMU inertial sensor are used to measure the wave-induced effect on the protecting surface block.Based on the principle of coordinate system transformation in inertial navigation system,the IMU inertial sensor was mounted on the protecting surface block and placed in three different water line positions for testing,btain impact velocity and collision number.The results show that the collision number is larger at z/D_(n)=-2 than at z/D_(n)=0 and z/D_(n)=2,and the maximum impact velocity occurs at z/D_(n)=0.The above measurement parameters can provide quantitative evaluation for block protection.
