Abstract
Four-wheeled vehicles are often tested on indoor, four-poster road simulator rigs. Road loads are simulated with the use of servo-hydraulic systems for suspension set-up optimisation, NVH analysis, fatigue life cycles.
The use of a road simulator is not so common practice for two-wheeled vehicles despite problems to be faced are extremely similar.
The paper presents a device for testing motorcycles on a Servotest four-poster. A dedicated restraint system had to be devised in order to support the motorcycle without altering its inertia characteristics. Additional pneumatic actuators with a purposely developed instrumentation have been designed to reproduce braking and power thrusts.
