Test

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

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.
