    Modeling force from thermal gap pad material

    Hi, I'm currently working on a problem involving a printed circuit board (PCB). This PCB has a number of discrete chips which are being cooled via a large common heatsink. To transfer heat from the individual chips to the heatsink, each chip has a piece of gap pad material compressed between...

    Displacement results from Dynamic Analysis, Modal Analysis

    I believe I found the issue, and just wanted to post it here should anyone else run into the issue. When I was doing my dynamic frequency analysis, I always had my input set relative to ground. This gave me good acceleration curves, but gibberish for displacement. Changing the input to be...

    Displacement results from Dynamic Analysis, Modal Analysis

    Hello, I'm in the process of doing a vibration analysis for a client, who wishes to derisk their design with respect to vibration. I was able to successfully get the model to run, performed the modal analysis,and determined the modal shapes and natural frequencies. However, when looking at...

    Contact Region in Dynamic Analysis

    Thanks for the replies. I tried just doing the bolted connections, and it gave me the same results as the mated (bonded) parts. Reading thru the Help, they do mention that one may need to create a free interface between mated parts so that Mechanica doesn’t bond them together. Putting a free...

    Contact Region in Dynamic Analysis

    Hi, I'm attempting to do a vibration analysis using Pro-Mechanica WF4. Essentially, I'm trying to predict the vibration response of a unit, attached to a mounting plate with 4 bolts in the corners, with this assembly attached to a shaker table with 6 bolts. I'm looking at the unit and its...
