- Summary:
- Abstract The steering system of commercial vehicle isasymmetrical to left side and right side, this causes vehicle pullduring braking application. This directly affects the safety of thedriver and vehicle ride and handling performance. In a similarway, the asymmetrical suspension parameter unintentionally setduring vehicle assembly are also major contributors for creating avehicle pull. After application of brake force, the tire contactpatch creates a moment about the kingpin axis. However, this momentgenerated is different on left and right-side due to asymmetricaldesign parameters resulting in vehicle deviation from its intendedpath. A large deviation may lead to on road accidents. Some of themajor factors which are responsible for the vehicle pullingphenomenon are the asymmetrical steering system compliance,asymmetrical suspension geometry, tire, braking system, road camberetc. The present work is useful to analyze the effect of change(left to right side) in the asymmetrical Steering wheel parameteron vehicle pulling at the early stage of vehicle development. Onproduction vehicles, it is practically not possible to achieve thesame parameter on both sides. Therefore, it is important to predictthe vehicle response to these variations and how does it affectvehicle handling characteristics. A full vehicle model is builtwith different vehicle subsystems in MSC ADAMS/Car. The Vehicledynamic Simulation were conducted to measure the amount of vehiclepulling by application of brake force on each wheel. This modelacts as input to ADAMS/Insight® for DOE study. The systematic DOEstudy is carried out to check the impact of different parametersi.e., cross camber, cross caster, cross toe, and cross scrubradius, on the vehicle behavior during different brakingconditions. Based on this DOE Study the influence of each parameteris estimated on vehicle stability during straight-aheadbraking
