    Insufficient Data in File

    DLT, Thank you. Do you have contact info for the tech support people in Santa Monica? Are you sure it is the OUT extension file? My system does not recognize that as a text file although it does for the LOG file and it lists the Nodes, Elements, DoF, and Results time. Weldments are much...

    Insufficient Data in File

    Thanks JT. I am getting the same error on another similarly sized test. I think we will need to upgrade quick. Mike

    Insufficient Data in File

    jte, I have 20 GB of hard drive allocated to this process. Mike

    Insufficient Data in File

    jte, Thanks for the reply. I had been using a solid, high quality mesh with the default mesh size. When I changed to Draft quality I did get results although on occasion Solidworks would shut down. I was not keeping track of the number of elements but since using draft settings I have been...

    Excuse me, that was Insufficient Data in Results File. Mike

    Insufficient Data in File

    Does anyone out there know how to trouble shoot the error: Insufficient Data in File? I am trying to analyze a pull test fixture made up of a 12' x 4.5' base of I-beams and a thick plate with a shackle mount attached and braced with I-beams cut at 45 degree angles on either end. These add up to...

    King Pin Load for Semi-Trailer

    All, Thank you very much for the valuable insight. Mike

    King Pin Load for Semi-Trailer

    What is the typical hitch weight (percentage of trailer weight) placed on the king pin of a semi-trailer? I know gooseneck trailers use around 20% but it seems like semis must carry more based on how far rearward their axles are. Thanks for the help, Mike

    Cordless Drill Torque at Speed

    Thanks geekEE. My head wasn't in the game.

    Cordless Drill Torque at Speed

    So you are saying that at the midpoint the drill puts out 300 in.lbs of torque while the shaft is turning at 900 RPM? That seems high to me.

    Cordless Drill Torque at Speed

    I am looking at a 28 volt Milwaukee Electric Tool drill: V28 1/2 in. Hammer-Drill #0724-20. The low speed setting is up to 600 RPM, the high speed setting goes to 1800. The manual lists low speed torque as 600 in.lbs. and the high speed at 300 in.lbs. I am trying to get an idea of how much...

    Cordless Drill Torque at Speed

    Is there a way to find out the approximate torque of a cordless drill at a certain speed? All of the manufacturers I have found only list max torque and then speed ranges. Is the max torque when the unit is stalled? Thanks, Mike

    12vdc Reversible Motor

    sreid, That is what I thought but I figured I should ask a simple question on here rather than at work. Thank you, Mike

    12vdc Reversible Motor

    Matt, The speed reducer itself does not contain a braking system but one is required. Would this be a special motor or could a permanent magnet motor, for instance, be wired to be reversible? Thanks, Mike

    12vdc Reversible Motor

    I am working on an application that requires around 1/2 hp to act on a speed reducer which will output the torque we need to lift a heavy load slowly. We are considering using a hydraulic set up but it would be more compact and hopefully cheaper using a small electric motor. The only...

    Speed reducer, shaft, and pulley lifting problem

    Ross, I see. I was under the (apparently erroneous) impression that the speed reducer output shafts were independent of each other. That makes it clear that I must use a smaller drum which will be useful anyway as I was coming up with a required output speed of only 2.87 - 4.30 RPM to lift the...

    Speed reducer, shaft, and pulley lifting problem

    I need to calculate the torque required from a speed reducer to lift a load. The lifting system involves a motor attached to a dual speed reducer which will attach via a coupler on either side to 1” shafts. On the end of each shaft will be an 8” V-grooved drum. To each drum I will fasten two...
