Development of a Database for Model Parameterization, Tire Performance Evaluation, and Analysis of In-Plane Spindle Forces

Prokop, Günther / Pang, Yun

Tires are one of the most important vehicle components since they significantly affect vehicle attributes such as handling stability, steering controllability, ride comfort, and structure durability. However, whether for tire competitive benchmarking or vehicle conceptual design, data insufficiency tends to restrict the development process. This article presents a procedure of establishing a database for the evaluation of tire and vehicle impact vibration. Forty-three tires with various sizes and usages were selected to build the datasets. The rigid ring model was used to characterize each individual tire sample on account of our application requests. In view of the test resources, an optimization approach to the standard parameterization method was proposed and fully validated with the measurement database. The parameter characteristics were then statistically investigated and compared between the different tire types. A criterion “peak-to-peak” was put forward to quantitatively assess the spindle responses by impact cleat. In-plane spindle forces were finally analyzed regarding the tire properties based on the parameter database.
