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 Tracked Vehicle, 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.
