In this presentation, we’ll demonstrate how to use MATLAB to support the teaching of rigid body dynamics – one of the staples in physics and engineering courses. A collection of case studies from Mechanical and Mechatronic engineering will be presented, spanning 1st year concepts through to more advanced 3rd and 4th year rigid body dynamics. Specific case-studies will include:
- Kinematic analysis of a 4-bar linkage
- Equations of motion of a 3-Link robotic manipulator (Newton)
- Gyroscopic Boat Stabilization (Lagrange)
- A quadcopter that balances an inverted pendulum (Lagrange)
For each case study, a Computational Thinking approach to problem solving will be demonstrated. MATLAB Live scripts are combined with symbolic computing, allowing the "conceptual" steps of the equation of motion derivation to be clearly defined. Because the laborious computations are NOT being done by hand, students are "liberated" to apply and explore concepts while they're formulating the solution.
Once the equations of motion are derived, Simulink is used to implement the hand derived equations - allowing the students to see the "cause and effect" behavior for this system. The hand derived models are also validated against Simscape Multibody models – where CAD like animation viewers are connected to the simulations.
