- Abstract
- The properties of the system parameters in a vehicle have uncertainties due to material irregularity, manufacturing tolerances or any other uncertain factors. Since the uncertainties of the system parameters lead to the uncertainty of the vehicle ride comfort, the uncertainties of the system parameters are direct causes of declining reliability of the vehicle ride comfort. So, the uncertainty of the vehicle ride comfort should be analyzed and considered for reliable design of the vehicle ride comfort. In order to analyze the uncertainty of the vehicle ride comfort accurately, exact probability distributions of the uncertain system parameters are needed. In most of practical situations, however, obtaining the exact probability distributions of the uncertain system parameters is almost impossible because of the limited time and cost. For that case, the reliability of the vehicle ride comfort cannot be obtained. Therefore, the reliability of the vehicle ride comfort should be estimated using limited samples of the uncertain system parameters. For the purpose, samplebased reliability estimation method employing an extreme value theory was proposed in this paper. Using the proposed reliability estimation method, reliability design of the vehicle ride comfort was conducted.
