Test

The Test component is required to define the options in the Test Properties section.


Figure 1. Test Component

Inputs

Test Type
Defines the type of test to execute the test process. By default, Spring and Shackle type is used for the test.
Testing Directory
Defines the folder location where all of the test files will be generated, such as .mdl, .xml, .plt etc.
File Label
Used to enter the required test file label.

Spring and Shackle - Force/Motion Inputs

Actuator
Depending on the type of Test Rig selected for deflection option, it can be a force or by applying motion.
Offset Force/Displacement
Used to set the initial force/displacement value before the load cycle is started.
Jounce Force/Displacement
Used to enter the force/displacement value for the jounce part of the cycle.
Rebound Force/Displacement
Used to enter the force/displacement value for the rebound part of the cycle.

Spring-only (SAEj510) - Motion Inputs

Curb
Displacement to push system to curb position.
Design
Displacement to push system to design position.
Metal-Metal
Displacement to push system to maximum deflection position.

Simulation Settings

Print Interval
Used to set print interval for the output .plt file.
Step Size
Used to set the step size for Solver.
Simulation Type
Defines the simulation type; Quasi-static or Transient.
End Time
Define the cycle-time for force deflection.
Build Leaf
The tag that defines if the MDL is to be built when Run Test Rig button is clicked.
Run Test Rig
Click to run the test event on the leaf spring.
