20-sim, the dynamic modeling and simulation package for iconic diagram, bond graph, block diagram and equation models

By: 20-sim  11-11-2011

20-sim is a modeling and simulation program that runs under Microsoft Windows. With 20-sim you can simulate the behavior of dynamic systems, such as electrical, mechanical and hydraulic systems or any combination of these.

20-sim fully supports graphical modeling, allowing to design and analyze dynamic systems in a intuitive and user friendly way, without compromising power. 20-sim supports the use of components. This allows you to enter models as in an engineering sketch: by choosing components from the library and connecting them, your engineering scheme is actually rebuilt, without entering a single line of math !

Bond Graphs | Bond graph modeling with 20-sim

For every port you can specify the causality as fixed preferred, indifferent or depending on the causality of other ports. Since then a continuous effort to improve bond graph modeling has made 20-sim the standard in bond graph modeling. 20-sim will rewrite the equations symbolically to remove algebraic loops and differential causalities. Causal strokes indicate the direction of the efforts and flows in a bond graph model.


Torsion Bar 1.0 Mechatronics Trainer

The stiffness of the flexible beam is deliberately chosen very low to ensure that the anti-resonance and resonance frequencies are clearly visible. The Torsion Bar 1.0 setup is equipped with a PWM controlled H-bridge motor amplifier that allows you to control the motor speed. The Torsion Bar is a prototype machine that can be used to teach the basics of mechatronics and machine control.


20-sim Classroom kit | special offer for universities

A 20-sim Classroom Kit allows you to use as many copies of 20-sim as you like, both at the Laboratory and for students and members of the Laboratory at home. The Classroom Kit may only be used as part of the regular work of the laboratory and the regular education given by the laboratory. Controllab Products takes care that every year an update of this license is shipped to the laboratory.


20-sim 4C | Controllab Products B.V

Values are transmitted from the target to 20-sim 4C in real-time with sample rates up-to 100 Hz or off-line with the full sample rate. Monitoring and Logging: In 20-sim 4C you can monitor and log every variable that is available on the target. Targets: With 20-sim 4C you can run code on any target that runs a RTAI Linux operating system like PC's.


Controllab Products B.V. | TS-7300 Demonstration Kit

Various models are supplied to test the sensor and actuator aswell as models that combine the sensor and actuater, control the brightness with the potentionmeter. The TS-7300 Demonstration Kit is an TS-7300 board with extras to quickly discover the power of modeling & rapid prototyping with 20-sim & 20-sim 4C. Sensor: A sample sensor, a potentiometer, is supplied to demonstrate the analog to digital input of the TS-7300 board.
