查询词典 foundation plate

The theoretical solution of eigenfrequencies and vibration models of rectangular thin plate on foundation with completely free boundary was derived by the double finite cosine integral transform method. In the analytical process, the elastic foundation was regarded as Winkler foundation model.

In reservoir design one sometimes meets with submerged structures, such as the underwater retaining wall, the foundation-rested immersed, plate which connects shore to intake-tower, the half-submerged navigation-guiding plate, a strut plate positioned midway in water depth, and also a diversion wall from shore.

在实际工程中，有时遇到某些建筑物是潜没在水中的，如水库水面以下的挡土墙和水库进水塔与岸边连接的撑墙；又有时遇到挡水建筑物与基础脱离，如水库中的导航板；另外还有一些既潜没在水面以下又与基础脱离的建筑，如水中撑板；还有岸边的平板。

In this paper,the raft is approximated by a thin plate with regular shape at first.Then the floating raft system is divided into several subsystems,such as plate raft,elastic foundation,etc,which are respectively modeled by four-parameter net method.After that,dynamic absorber and active absorber are put into a uniform frame to obtain the model of plate raft subsystem coupling with them.At last,according to the force and velocity relationship among each subsystem\'s interfaces,the entire plate floating raft system is modeled by subsystem structural admittance synthesis method.As the main structure of floating raft system is elastic,it is inevitably to study the optimization of actuators\' mounting positions before designing control law.In this paper,two new criterions are proposed for it.

本文首先将浮筏的中间筏架用一个规则形状的薄板近似；然后再将浮筏系统分解成若干个子系统，如板式筏架子系统、弹性基础子系统等，运用四端参数网络建立了它们的动力学传递方程，传递特性由导纳矩阵描述；接着，将动力吸振器和主动吸振器的(来源：ABC90论文00网www.abclunwen.com)分析统一于一个框架内，获得了与吸振器耦合的板式筏架子系统的动力学传递特性；最后，根据各子系统在各界面上的作用力和速度的相互关系，通过子系统结构导纳综合方法获得了整个板式浮筏系统的动力学传递方程，并在此基础上获得了系统的力传递函数模型。
