    Master/Slave Master Cylinder

    Have been searching the internet all day for something that I was sure would exist: an electronically actuated master cylinder. For my system, I have a slave (output) cylinder that is mounted remotely in a very tight space, so no room for using direct electrical actuation on the output...

    Piezo Contact Sensor

    We currently use an MSI laminated piezo film strip sandwiched between a cover plate and the vehicle to detect contact between a given surface of the vehicle and anything else in its surroundings (MSI P/N 1-1002405-0). We have a new project that requires a smaller sensor. Basically, the...

    Trailing Link Flexure

    Does anybody know of current designs that utilize a/multiple flexure joints as a substitute for a spherical type joint? I have been considering ways to accomplish this for the purposes of a racing suspension, where it is generally required that a trailing link joint be very stiff along the axis...

    Selecting Specific Temporary Axes

    Is there a way to determine which feature the temporary axis I am selecting belongs to (it seems length of the axis is a rough indicator, but not good enough sometimes)? I am concerned w/ selecting specific temporary axes b/c in a part w/ concentric features, I would like to associate as much...

    COSMOS Buckling Tutorial

    Background: I have recently installed COSMOSWorks and am trying to follow through some tutorials, but I am especially interested in the buckling tutorial. However, when I get to the point of running the analysis (after, meshing, mat'l definitions, etc.) I get a pop up w/ the following text...

    Hole Callout Precision

    Is there a way to get an independant # of decimals on the diam. & depth of a hole in a callout (differing decimals = different tolerance on diameter vs. depth)?

    Aero/streamline tubing shape

    I am trying to define the shape of standard aero/streamline drawn tube. There is a MIL spec that gives some inspection dimensions and major and minor lengths of the tubing, however, it does not seem as though I have enough info to fully define the shape for modeling (stress analysis not CFD)...

    Looking for Odd Compression Spring

    OK, so I've spent about a day looking for a compression (return) spring for an air jack assembly. The problem now is that the spring binds on its housing due to diametral expansion of the spring when it compresses. I have checked several stock spring listings for various companies and...

    Chamfer Along Portion of Edge

    I have been messing w/ trying to make a chamfer that only covers a specified distance along an edge. The chamfer tool doesn't seem to facilitate this, and I cannot use the sketch chamfer tool b/c the chamfer is on an edge created by an extrusion process. The closest I have come is to sweep...

    shock friction

    Another recent thread mentioned the problem of friction in shocks due to the side loading imparted on the shock when a coil over spring buckles under compression. I have been curious about how big of an effect this is (I would like to see some numbers). The main problem that I see w/...

    panhard bar suspension FRC

    I am writing a program to output the SS wheel loads for my racecar. The car has front and rear solid axles w/ panhard bars. The vehicle is a left turn only racecar and therefore the CG is offset. What I have determined, and what I would like to confirm, is that the FRC (force RC) for a...
