AUTOMATED SYSTEM SYNTHESIS FOR ELECTRIFIED MOBILE MACHINERY

Abstract

The electrification of mobile machines leads to new drive solutions.Not only the electric drive components are newly deployed, but also the mechanical and hydraulic drive components can be utilized in a new or different way.This allows more efficient systems to be built and new advantages to be exploited.Conventional development processes require the developer to select a specific drive concept to be investigated at an early stage.The drive concept is then examined by means of simulations and/or experimental tests.The suitability of the drive system for the application is only evaluated after its detailed investigation and an iterative process.The overall process leads to a high effort and requires a large amount of time.Thus, it is economically not possible to evaluate many different system combinations with conventional methods.This paper proposes a tool to improve the development process.A methodology for an automated drive system evaluation is presented both structurally and in terms of how individual components are modelled.The methodology aims to deduce functioning system topologies based on load cycles.An analysis on the influence of different load cycles is therefore conducted.
