Coupled Mass Spring System Dynamics Solver

Coupled Mass Spring System Dynamics Solver is a C# application designed to analyze the dynamic behavior of a two-degree-of-freedom (2 DOF) coupled mass-spring system. This software allows users to study the system's response to initial conditions, external sinusoidal forces, and damping effects, providing insights into both the transient and steady-state behavior of the system.

Features

• Time vs Response Analysis:

  • Analyze how the system transitions from transient to steady state over time.
  • Observe the effects of initial displacements and velocities on the system's response.

• Frequency Response Analysis:

  • Explore the system's Dynamic Amplification Factor (DAF) or Response Amplitude Operator (RAO) by plotting the magnitude of displacement, velocity, and acceleration at node 1 or node 2.
  • Study the frequency response of the system across a range of forcing frequencies applied at either node.

• Plotting and Exporting:

  • Plot time vs response or frequency response curves.
  • Export results to a text file for further analysis.
  • Save plots as PNG images for easy sharing and documentation.

User Interface

The application features a user-friendly interface that simplifies the setup and analysis process:

• Input Parameters:

  • Easily input mass values, stiffness coefficients, modal damping ratios, and other analysis settings.
  • Customize external forcing functions applied to either node 1 or node 2.

• Interactive Plotting:

  • Zoom in and out of plots using the scroll wheel.
  • Pan across plots by holding the right mouse button.
  • Double-click the middle mouse button to reset the view and fit the plot to the window.
