UM 3D Contact
Universal Mechanism v. 5.0.2 including the module
UM 3D Contact that is intended for simulation of contact interaction between
bodies based on its contact manifolds is published on the web site. The module extends the possibilities of calculation of contact interaction between bodies that are implemented in
Universal Mechanism. The realized contact algorithm is based on the simulation of interaction of arbitrary convex polyhedrons. Force model includes viscous-elastic normal force and
Coulomb dry friction that supports both sticking and sliding modes.

November 2007
The meeting that was devoted to “Using Universal Mechanism Software for simulation of derailment cases”
took place in headquarters of
JSC Russian Railways in Moscow under the chairmanship of the
vice-president of Russian Railways on 29th of November, 2007. Representatives of several departments of Russian Railways, VNNIZHT,
VNIKTI and other institutes and enterprises took part in the meeting. As a results the decision to recommend Universal Mechanism
software as a basic tool for
simulation of railway vehicle dynamics and derailment cases were approved.
Unigraphics NX
Developing the interface between Unigraphics NX and Universal Mechanism is finished. Library

export of data from Unigraphics NX to intermediate UCF (UM CAD File) format is published on our site.
UM Ballast
Materials which are devoted to the new UM module for simulation of granular media dynamics is now published on our web page.
Combining powerful methods of UM mathematical core and fast algorithms that calculate contact interaction between particles
the module has unique possibilities. It allows simulating processes of loading, crushing, separation, vibratory consolidation and
displacement, etc.

The biggest Russian producer of freight bogies and wagons the
State Unitary Enterprise "Production Association "URALVAGONZAVOD"
starts using UM software for estimation of dynamical and
fatigue properties of freight wagons that are one of the basic products of the enterprise. Three specialists were trained
and several dynamical models of railway vehicles were considered during introduction course, 24-28 September 2007. We thank our
distributor
Delcam-Ural company for organization of this training.

Program package "Universal Mechanism" is intended for simulation of kinematics and dynamics of planar and spatial mechanical systems.
The program is oriented to practical engineers, students and teachers; in other words it is oriented to all people who are involved in problems of dynamics of machines and mechanisms. Mechanical systems are described by means of representing them as systems of rigid bodies connected by various kinematical pairs and force elements, so-called multibody systems.
Online animation of motion and plots of dynamical performances are available during simulation. There are lots of measurable dynamical performances of mechanical systems: linear and angular coordinates, velocities and accelerations, active forces and moments, reaction forces etc.
UM has an advanced postprocessor, which includes linear analysis, statistics,
multivariant calculation and optimization, and export of results. UM is a useful tool
for the computer-aided modeling of multibody and hybrid systems of various types: complex aerospace structures, robots,
railway vehicles, automobiles, cable systems, etc. It gives an opportunity to solve both the direct and inverse
kinematic, dynamic, and control problems. There are special prices of UM for scientific and educational purposes.
UM includes kernel and number of additional task-oriented modules:
UM Automotive,
UM Loco,
UM CAD Interfaces,
UM FEM,
UM Experiments,
UM Control and others.
Our engineers can help you to carry out dynamic research of your mechanical systems.
Download UM 5.1 and get three-month free license here.
Using UM for modeling of mechanical systems, main features of the program
package, its modules and lots of animations are presented here (PowerPoint presentation, zip
archive, 83 Mb).
