Calculation modules

Sea Tech Ltd. has exclusive distribution rights
to distribute RodsFem and EquBrus calculation modules in Russia

 

 

   RODS FEM

 

RODS FEM - Flat Rod Systems Calculation Modul.

Calculations are performed by the finite element method in a rod approximation. Input of initial data is made from a text file. The following types of loads are provided for each rod:

- distributed according to the linear law into parts of the rod length,

- a concentrated transverse force,

- concentrated longitudinal force (however, the complex bending of the rod is not yet considered),

- a concentrated moment.

 

Frame/slab assemblies can be free or rest on a support. Support conditions are formed by combining three types of movement restrictions: longitudinal to the X-axis, longitudinal to the Y-axis and rotation. Each of these limitations can be either rigid (i.e., no movement along the given coordinate) or flexible. When calculating frames, it is possible to introduce a free node, i.e. such a node in which the rods do not transfer rotation to each other. This makes it possible to calculate, for example, structures such as boom rods with backstay cables.

Shear deformations and torsional stiffness of beams can be taken into account (when calculating slabs).

 

The Rods Fem calculation module has been taken into account by the Russian River Register

 

 

   EQU BRUS

 

EQU BRUS is a module for calculating the equivalent hull beam.

The program is based on the standard method of calculating the equivalent beam, described, in particular, in the work of Y.I. Korotkin and others - "Ship strength".

As in the previous case, the initial data are specified in a text file. Data control is carried out on the graphical image displayed in the program window.

The figure shows the design scheme of an equivalent river tanker beam, typed by the longitudinal scheme:

 

Equ Brus calculation module has a certificate of the Russian River Register
