The goal of this paper is to discuss the critical aspects of damper tuning for production vehicles. These aspects include ride and handling performance attributes, damper basics, conflicts in achieving desirable results, tuning philosophies, and the influence of the damper design. The marketplace has become increasingly competitive. Customer preference, cost, mass and regulatory pressures often conflict. Yet each year more vehicles are required to do all these things well. Damper tuning can play a significant role in resolving these conflicts. Although many papers have been written on the theory behind damper design and capabilities, there has been very little written about the techniques of tuning dampers for production vehicles. This paper attempts to discuss the critical aspects of damper tuning for production vehicles in four sections. The first section discusses the performance attributes of ride and handling. The second section provides a basic understanding of dampers.

This paper discusses subjective and objective approaches to quantifying ride performance in three sections: (1) Separates overall ride quality into five components-impact feel, shake, isolation, motion control, and smoothness; (2) Discusses approaches to objectively quantifying ride performance; (3) Provides analytical and test data to illustrate trade-offs in performance between the components of ride. The final section of this paper presents customer clinic data indicating customer preferences for the trade-off balance between ride performance attributes, specifically motion control versus smoothness.
