USING SENSITIVITY ANALYSIS FOR MODELING VEHICLE DYNAMICS

Abstract

The objective of the paper is to analyze experimental data and to identify the relationship between different measured parameters using sensitivity analysis. Sensitivity analysis is a technique used to determine how different values of an independent variable will impact a particular dependent variable under a given set of assumptions. It is useful for testing the robustness of the results of a model or system in the presence of uncertainty, increasing understanding of the relationships between input and output variables in a system or model, searching for errors in the model by encountering unexpected relationships between inputs and outputs, model simplification by fixing model inputs that have no effect on the outputs. In our study, data were obtained by measuring the dynamic parameters of vehicles and engines. Testing program aimed to capture a large range of operating regimes. The study noted the need to perform sensitivity analysis before developing mathematical models of vehicle dynamic
