FE structural analysis
Based on decades of experience, ISATEC applies finite element analysis FEA efficiently and purposefully in its projects.
These structural simulations are utilised, for instance, to examine frames, casings, components, machine elements, rotors, pressure vessels and supporting structures. Based on calculated deformations, stresses and natural frequencies, strength as well as stiffness and the avoidance of vibrational response are verified. These analyses are conducted in the early design stage with rough models; in the further course of the project, proof is obtained using the realised construction.
The figure shows the initial natural frequency of a slender component using a stranding rotor.
Multi-body simulation MBS
Mechanisms or gears are used for defined guidance of components or to transmit forces and movements. A simple example of a transmission gear unit is the toggle lever shown (left side of the figure), in which the input force Fin is converted to the output force Fout. Due to the kinematics of the toggle lever, the input force is constantly increased in the direction of the extended position (right side of the figure). This property is used e.g. in pressing or clamping devices.
ISATEC is an expert partner from the conception (synthesis) of motion mechanisms and their design all the way to the fully engineered solution. Simulation methods regarding dynamics of multi-body systems (MBS) are used to consider effects such as inertial forces/moments and gyroscopic effects, even for complicated mechanisms. MBS results consist of the path of movement and also the associated loads. By combining MBS with the finite-element method (FEM), it is also possible to determine the elasticity of components and stresses occurring in the components directly for the entire movement sequence, as shown in the figure for a coupling element as an example.
