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.
The user selects the time step and total time. The 1st natural frequency can be calculated and the 1st time period/1000. (1/(1000f1)) is a good starting time step. The total time should be at least 3 time periods (3/f1). There is a limit of 200,000 total steps. The results are animated for the dropped weight node. All the results can be downloaded to a CSV file.
Only one weight can be dropped. If multiple nodes are given weights on the 1st one from the left is used.
The nodal deflection plot is the dropped weight node.
The dropped weight can be given a coefficient of restitution value. A value of 1 is a full return bounce. A value of 0 is no bounce and the weight "sticks" to the mean and adds mass to it.
