Create a random load event

1. Make the Simulation file the work part and the displayed part, and choose Specialist Durability tab→Load Events group→Random Event .

2. In the Name - Description group, in the name box, type a name for the random load event.

3. In the Data Source group, from the Data Source list, select a predefined random data source.You can also click Create Data Source to create a random data source, using the Random Data Source dialog box. For more information, refer to Create a random data source.

4. In the Scaling group, in the Scaling Factor box, type a greater than zero factor for scaling the vibration and correlation input functions that are defined in the load event’s random data source.

5. In the Durability Options group, select one of the following methods to compute the probability distribution of the random load that is defined by a power spectral density (PSD) function.Dirlik for typical durability loadsNarrow band for narrow band loadsEquivalent sine wave for a fast durability analysis

6. (Optional) In the Load Length group, type the duration of the load event in the Duration box.

7. (Optional) In the Distance subgroup, select Enter Distance from the list, and type the distance of the load event in the Distance box to specify the load event's corresponding riding distance.If you select No Distance Information Available from the list, the software does not generate any mileage information for the post-processing.

8. (Optional) In the Temperature Source group, from the Temperature Source list, select a predefined temperature source.You can also click Create Temperature Source to create a temperature source, using the Temperature Source dialog box.

9. Click OK.
