Setting parameters

To illustrate the use of the Experiment view, we will vary the value of mass parameter in the Body mass component.

Figure 70: Setting the Body mass value

We are going to set several different values for this parameter, perform a run for each value, and save each of these parameter and result sets as experiments.

To do this, we require the Experiment view, which you activate through the Edit > Show/hide menu.

Remember that you can drag this and other panes around the Simcenter Amesim workspace to suit your preferences.

Set the first values for the mass and run the simulation

Procedure

1. Set the following parameters:

Submodel name and type

Main simulation parameters

1d translation mass [MECMAS21]

mass [kg] = 400 inclination [degree] = -90

linear spring with 2 ports capable of linear motion [SPR000A]

spring rate [N/m] = 15000

1d translation mass [MECMAS21]

mass [kg] = 50 inclination [degree] = -90

linear spring with 2 ports capable of linear motion [SPR000A]

spring rate [N/m] = 200000

step signal source [STEP0]

value after step [null] = 0.1 step time [s] = 1

2. Open the Run Parameters and set a Final time of 5 seconds with a Print interval of 0.002 seconds.

3. Perform a dynamic simulation run and plot the following variables together:

Body mass: body displacement

Wheel mass: wheel displacement

Step: step output

Figure 72: Plot the variables

Results

Keep this plot open until the end of the example.
