Accelerated Motorcycle Testing Using Laboratory Simulation Methods

Laboratory simulation methods have been used for many years in the automotive industry to accelerate durability testing of vehicle chassis and suspension members. Laboratory simulation technology is now being applied successfully to motorcycle development programs. Laboratory simulation methods and technologies provide several advantages over conventional proving grounds test methods. Typically, laboratory testing reduces testing time and cost, provides more repeatable tests, reduces maintenance and eliminates weather delays, does not require a running engine or drivetrain, and generally has fewer uncontrolled variables. Usage data is recorded in the form of suspension reaction forces, moments, or motions as an input to the simulation process. These inputs are simulated, and this data can be readily fed back to the design team to help refine FEA models for design improvements. Vehicle and rider dynamics can be safely observed as suspension parameters and adjusted in a repeatable laboratory setting. Dynamic analysis can be used to animate various running modes on the simulator, and noise, vibration, and harshness (NVH) problems can be isolated as being engine & drivetrain induced or road induced vibrations. Due to these factors, laboratory simulation testing is helping motorcycle manufacturers reduce their product development cycle time and improve overall quality in the process.
