Active Suspension: Simulate Road Conditions Without Sitting in Traffic
Give your senior engineering students unique hands-on learning, relevant to the automotive industry with Quanser’s Active Suspension. This experimental platform teaches active control challenges for a quarter-car model, as well as mass, spring and damper systems.

How It Works
The Active Suspension system consists of two masses, each supported by a spring. The upper mass represents the vehicle body supported above the suspension, while the lower mass corresponds to one of the vehicle’s wheels. The middle mass corresponds to one of the vehicle’s wheels. You actuate the upper mass through a programmable motor. Conduct different experiments by positioning the device vertically or horizontally.
