The Selection of a Criterion to Evaluate Ride-Discomfort in Off Road Vehicles

As the operational duty of the off-road vehicle diversifies, the human factor becomes increasingly important in maintaining a safe and comfortable working environment for crew members. To allow designers to evaluate ride-comfort in off road vehicles, computer simulation techniques are being increasingly used. Models of a dump truck and a military tank have been developed (8) to predict vibration levels as these vehicles travel over typical terrain.
