Rotational Mass Damper System

Simscape simulation of a Rotational Mass-Damper system to analyze angular position and velocity response under physical constraints.

This project demonstrates the physical modeling of a Rotational Mechanical System using the Simscape environment. Unlike traditional signal-based Simulink blocks, this model uses physical connections to represent the exchange of energy between an inertia (mass) and a rotational damper.

System ComponentsThe model consists of the following key physical blocks:

• Inertia (Rotational Mass): Represents the rotating body with a specific moment of inertia.
• Rotational Damper: Introduces viscous friction, where the damping torque is proportional to the relative angular velocity.
• Ideal Rotational Motion Sensor: Measures the mechanical variables (Angular Position and Velocity) without affecting the system dynamics.
• Mechanical Rotational Reference: The fixed "ground" point for the rotational circuit.
• Solver Configuration: The essential f(x) = 0 block that manages the numerical simulation of the physical network.

Key Features

• Dual Output Tracking: Simultaneously monitors Angular Position (Pos) and Angular Velocity (Vel) through a synchronized Scope.
• Physical Domain Modeling: Uses across and through variables (Torque and Angular Velocity) rather than just mathematical signals.
• Dynamic Response: Perfect for studying settling time, damping ratios, and rotational stability in mechanical engineering applications.

How to Use

1. Open the .slx file in MATLAB.
2. Adjust the Inertia and Damping Coefficient values by double-clicking the respective green blocks.
3. Click Run.
4. Open the Scope to visualize how the rotational mass reacts over time.
