Symbolic Math Toolbox is used to derive a mathematical model of a basic engineering system
|31 Aug 2009||Linda Webb||
When modeling engineering systems, it can be difficult to identify the key parameters driving system behavior because they are often buried deep within the model. Analytical models can help because they describe systems using mathematical equations, showing exactly how different parameters affect system behavior.
In this article, we will derive analytical models of the loads and bending moments on the wing of a small passenger aircraft to determine whether the wing design meets strength requirements. We will derive the models in the notebook interface in Symbolic Math Toolbox™. We will then use the data management and analysis tools in MATLAB® to simulate the models for different scenarios to verify that anticipated bending moments are within design limits.
