Model-Based Design for Off-Highway Machine Systems Development

By Sameer M. Prabhu, MathWorks


Design engineers are using Model-Based Design to address the difficulties that traditional development processes are experiencing due to increased use of electronic controls in off-highway machines.By using models in the early design stages, engineers can create executable specifications that enable them to immediately validate and verify specifications against the requirements. These models also allow the machine designer to evaluate the complex interactions between mechanics, hydraulics, electronics, and other physical phenomena, and detect design errors when the cost to fix them is less.

This paper provides an overview of Model-Based Design for off-highway equipment machine systems development . It illustrates how engineers have developed a dynamic model of a machine and the electro-hydraulic implement and propulsion system, which is used to verify the overall machine behavior. The models are linked to the machine requirements and instrumented to check the simulation results to achieve verification of machine behavior against requirements in a formal way.
