Calculation of Mobile Machines in Variable Operational Environment

Abstract

Classification of calculations in a system "Driver-vehicle-road - Mechatronics/Adaptroniks - Driver assistants" is suggested. Three calculation groups - "Life-and-functional calculations" (LFC), "SIL/HIL-technologies" (SHT), and "Virtual tests" - are separated. The SHT and LFC are considered with great attention. Multilevel calculations of loading modes (from elementary modes to the general operation conditions) and design lives corresponding to them are described. Design life approximators are entered as a new calculating tool for representation and formation of calculation results under various operational conditions. Fundamental issues of reliability specification and calculation for the mobile machine as a system are analyzed, and an approach offered is presented.
