OSCILLATIONS

MAIN FEATURES

  • Selection of an unlimited number of dynamical systems for each analysis
  • Characterisation of each system through inertia, viscosity and stiffness coefficients for each degree of freedom
  • Description of initial conditions and forcing functions over time
  • Solution of ordinary differential equations (including either linear or non-linear terms) through an iterative numerical method
  • Time history analysis of position, velocity and acceleration for all systems and all degrees of freedom
  • Computation of trajectories in the phase space
  • Stability analysis
  • Comparison of analytical results with available field data
  • Visualisation of results
  • Suitable for designing and testing

TEST CASES

Figure 1, Figure 2, Figure 3 and Figure 4 illustrate the dynamical behaviour of a rigid body with six degrees of freedom subject to external excitations.

Figure 1. Position (Y-Axis) versus time (X-Axis).

Figure 2. Velocity (Y-Axis) versus time (X-Axis).

Figure 3. Acceleration (Y-Axis) versus time (X-Axis).

Figure 4. Velocity (Y-Axis) versus position (X-Axis) for both spatial and rotational degrees of freedom.
