Effects of bottom shear stresses on the wave-induced dynamic response in a porous seabed: PORO–WSSI (shear) model
Bottom shear stresses Wave-induced dynamic response Porous seabed “u–p&rdquo approximation Biot’s theory
2012/2/28
When ocean waves propagate over the sea floor, dynamic wave pressures and bottom shear stresses exert on the surface of seabed. The bottom shear stresses provide a horizontal loading in the wave-seabe...
水稻种绳直播机对地表不平度的动态响应（Dynamic Response of Taped Type Rice Direct Seeding Machine for Field Surface Roughness）
水稻 种绳直播机 地表不平度
2009/9/11
为了探索水稻种绳直播机对地表不平度激励的适应性，进行了动态模拟试验。根据样机的结构特点，设计了由角位移传感器、数据采集卡和计算机等构成的地表不平度检测系统。检测了由旋耕形成的原始地表不平度和经过种绳直播机作业后形成的地表不平度，应用Matlab软件对信号进行了时域和频域分析。应用等同法建立了系统的传递函数，分析了系统的动态特性。研究结果表明，由种绳直播机和土壤等构成的土壤—机器系统是一个具有一阶惯...
Numerical Simulation of Dynamic Response of Structure Caused by Impact Pressure Using an Eulerian Scheme with Lagrangian Particles
Dynamic Response Eulerian Scheme Lagrangian Particles
