Why does the tilt pin have a big force when launch just begins?

I have conducted a launch analysis with MOSES. then I use the command LWFORCE  to explore the reaction force during the launch.

I found that the pin force is not equal to 0 when event =0. Actually it is a big number. But obviously the jacket  is not on the rocker when launch just begins.

MAY YOU HELP ME TO FIGURE OUT WHY THAT HAPPENS?

  • Hi Ju Peng,

    You give very little information.  I cannot provide a direct response to your question.

    I used the example files to try to recreate your problem.  I used in the install.cif file in the following directory.

    C:\Program Files\Bentley\Engineering\MOSES CONNECT Edition V10.10\hdesk\runs\samples\install

    I ran it with only launch active.  After the initial analysis I restarted MOSES.  I issued the following commands:

    prcpost

       lwforce

       report

       end

    end

    The resulting Skidway Reaction report was the same as that in the original out0001.txt file.

    I was not able to recreate your problem.  Please provide files or provide more information.

    Thank you,
