Dropped Weight on Beam

This module will calculate the beam dynamic response to a dropped weight. The usual beam options are available. Beam segment and nodal information can be entered via dropdown menus. This a numerical integration solution so the response is calculated at each time step.

Model summary

Inputs: Number of segments and their segment properties.

Inputs: Nodal boundary conditions. Drop weight and drop height.

Inputs: Weight coefficient of restitution and beam % critivcal damping.

Outputs:Dynamic response with motion of the weighted node given versus time.

Outputs: Animated beam response.

Useful hint 1: Nodes and segments are clickable for easy changes.

Useful hint 2: Configuration and results can be saved to a JSON file for future use.

Useful hint 3: Click the Calc Soln Parameters button for recommended time steps and duration.
