The Linear Flexible Joint is a passive linear cart that connects to the Linear Servo Base Unit through a linear spring. As an implementation of the classical mass-damper-spring quadratic system, the linear flexible joint is an ideal textbook-type experiment. The experiment is useful in the study of vibration analysis and resonance.

The Linear Flexible Joint experiment will help your students learn how to model and control real-world dynamic systems such as flexible couplings and gearboxes.
Designed in association with Prof. Karl Åström and Prof. Karl Henrik Johansson, the Coupled Tanks system consists of a single pump with two tanks. Each tank is instrumented with a pressure sensor to measure the water level. The pump drives the water from the bottom basin up to the top of the system. Depending on how the outflow valves are configured, the water then flows to the top tank, bottom tank, or both. The rate of flow can also be changed using outflow orifices with different diameters. The ability to direct water flow, together with variable outflow orifices allows for several interesting Single Input Single Output (SISO) configurations. Further, two or more Coupled Tanks can be combined together for Multiple Input Multiple Output (MIMO) experiments.
Same as the physical Ball and Beam, the virtual system features a track on which a ball is free to roll. The track is effectively a potentiometer, outputting a voltage proportional to the position of the ball. The tilt angle of the track is controlled by the Rotary Servo’s DC motor.
Same as the physical QUBE-Servo 2, the virtual system features a DC motor with the inertia disk and inverted pendulum modules. Rotary encoders measure the angular position of the DC motor and pendulum. The motor angular velocity is measured through a software-based tachometer.
Same as the physical Coupled Tanks, the virtual system features a single pump and two tanks. Each tank is instrumented with a pressure sensor to measure the liquid level. The different outflow valves configurations allow to direct the flow of the liquid, while the flow rate can be changed by using outflow orifices of different diameters.
The experiment is reconfigurable for various aerospace systems, from 1 DOF and 2 DOF helicopter to half-quadrotor. Integrating Quanser-developed QFLEX 2 computing interface technology, the Quanser AERO also offers flexibility in lab configurations, using a PC, or microcontrollers, such as NI myRIO, Arduino and Raspberry Pi. With the comprehensive course materials included, you can build a state-of-the-art teaching lab for your mechatronics or control courses, engage students in various design and capstone projects, and validate your research concepts on a high-quality, robust, and precise platform.
The Active Suspension consists of three masses that along stainless steel shafts using linear bearings and is supported by a set of springs. The upper mass (blue) represents the vehicle body supported above the suspension, the middle mass (red) corresponds to one of the vehicle’s tires, and the bottom (silver) mass simulates the road. The upper mass is connected to a high-quality DC motor through a capstan to emulate an active suspension system that can dynamically compensate for the motions introduced by the road. The lower plate is driven by a powerful DC motor connected to a lead screw and cable transmission system.
