Bungee Jump: Simulate Multibody Systems

Introduction

This is a simple model of a bungee jumper consisting of a mass attached to a platform by a spring and damper.

Automatic 3D Animation

Multibody systems have visualizers to show what a real-world system would look like.

To simulate the model and view a 3D animation of it, follow the steps below:

• Click the button in the top-right corner.
• When the build is finished, click the Simulate button .
• Click the Animate button .
• Use your mouse or trackpad to drag the animation to a good angle and zoom in with your scroll wheel or by using the trackpad. Then click the Play button to play the animation.

Instant Plotting

Explore the how the force on the cord varies with time by simulating and plotting the variable ElasticCord.f.

The variable will automatically be plotted when the model is simulated.

Change Parameters

Changing parameters for the simulation can be done rapidly in Simulation Center. Switch to the Parameters tab and enter a new value for the parameter you would like to vary.

Simulate again to see the effects of your changes.
