Modifying Force Values
You now modify the clamping and release force values to find the optimal force magnitude. You also plot the force values to see at what point the handle comes down to rest on top of the hook and when the overcenter_angle measure drops slightly below zero, creating a toggle force.
You can try different settings for the clamping and release forces to verify that the handle can be closed and released per the requirements.
Notes: | If the sensor is causing problems with the investigation, you can deactivate it: Click the background to ensure that nothing is selected. ■From the Edit menu, select Deactivate. ■The Database Navigator appears. ■From the Database Navigator, select the sensor. |
