Translational and Rotational Vibrations Virtual Lab

Virtual Laboratories developed in MATLAB Simscape for undergraduate level mechanical vibrations, control theory, and their associated labs

Vibrations and Control Virtual Lab Designed for Vibrations, Control Theory and Their Associated Laboratories

This repository includes translational, rotational, and control labs You can download and run simulations on MATLAB R2021b or newer versions of MATLAB.

You can also run simulations using MATLAB Online. The virtual labs can be utilized in undergraduate level Mechanical Vibrations, Control Theory and their associated laboratories.

Although Translational Virtual Lab consists of several mass-spring systems, Translational Virtual Lab v2 includes three more modules in addition to the mass-spring systems.

The learning objectives that are tied to the virtual labs are:

• Determine the natural frequency of SDOF
• Determine the natural frequnecies of MDOF
• Observe how the initial displacement of each mass affects the free vibration for a system with multi degrees of freedom
• Design a dynamic absorber and test to see how well your design works
• Identify the benefits of an absorber design
• Visualize the free and forced response of SDOF and MDOF systems
• Calculate the mode ratios and eigenvalues of MDOF systems
• Derive the equation of motion of vibratory mechanisms
• Validate the theoretical equations obtained from Newton's Laws of Motion or Lagrange Equations through simulations
