Short-Long Arm Suspension System Non-Linearities and Analysis

The redistribution of weight due to lateral loading through a short-long arm suspension system requires non-linear methods to accurately predict the steady state deflections throughout the entire vehicle system. An iterative analysis approach which recalculates suspension deflections and movement in the location of center of gravity of the vehicle provides an improvement over linear analysis techniques. Such analysis provides a better understanding of short-long arm suspension systems leading to improved handling at high lateral loading and/or improved noise, vibration and harshness characteristics.
