modeling mechanical systems

Estimation of the reduced mass in the collision of bodies.
When modeling the impact of two bodies, it is necessary to set the characteristics of stiffness and damping of the contact interaction. For a linear system (Kelvin-Focht model) these are stiffness and damping (dissipation) coefficients. Setting the stiffness characteristic is usually not difficult. Setting the characteristics of contact damping is not always convenient. Methods of determination of the reduced mass of impacted bodies are considered.

Update of the EULER software package - version 12 has been released

We continue to actively work on improving the EULER software package.

A big update of the software package - the 12th version of EULER has been released, in which the following important changes have been made:

  • a new computational core with significantly expanded capabilities has been developed;
  • increased calculation speed;
  • implicit integration methods are implemented, the use of which reduces the calculation time of rigid systems by orders of magnitude;
  • a number of user interface improvements have been made.
