船舶结构设计软件

结构有限元分析与计算

有限元软件 RFEM 是组成模块化软件系统的基础。主程序 RFEM 用于定义平面或空间的板、墙、壳和杆件结构等的结构、材料以及荷载作用。同时也可以用程序创建混合结构以及处理体单元和接触单元。

杆件结构设计与分析

空间杆件结构设计与分析软件 RSTAB 所包含的功能范围与有限元软件 RFEM 相似。该软件侧重于杆件结构的计算,更加容易操作,多年来它一直是进行结构分析的最佳选择。

船舶结构设计附加模块

对于船舶结构的力学计算和设计,建议使用钢结构领域内的附加模块。

    Form-Finding in RFEM

    The RF-FORM-FINDING add-on module determines equilibrium shapes of membrane and cable elements in RFEM. In this calculation process, the program searches for such a geometric position in which the surface stress/prestress of membranes and cables is in equilibrium with natural and geometric boundary conditions. This process is called form-finding (hereinafter referred to as FF). The FF calculation can be activated in RFEM globally in the "General Data" of a model, "Options" tab. After selecting the corresponding option, a new load case or a calculation process called RF-FORM FINDING is created in RFEM. An additional FF parameter is available for defining surface stress and prestress when entering cables and membranes. By activating the FF option, the program always starts the form-finding process before the pure structural calculation of internal forces, deformation, eigenvalues, etc., and generates a corresponding prestressed model for further analysis.
