Static Ride Analysis - Rear Suspension |
|
|
|
|
This is a quasi-static simulation during which the left and right suspension is exercised from jounce to rebound and various suspension parameters are calculated.
Required input: |
Vehicle parameters:
Suspension travel:

Description of task: |
The analysis consists of exercising the left and right suspension from design to jounce, followed by jounce to rebound simultaneously. |

Output: |
Reports containing some plots, tabular results, and graphical animation are automatically created. The following parameters are calculated during the simulation and the results are written to a text file (sdf.out). The same results are also written into the request file as user requests. |
