I need to determine the axial & radial loads resulting from a centrifugal blower to facilitate appropriate bearing selection & arrangement. The books I found all focused on centrifugal pumps for liquids, I have not yet found one that deals with these issues for air. Can anyone point me to a...
Hi all, I have recently cnc automated a large mill via retrofit. Main problem is occasionally the motors slip, so the software (mach 3) thinks motion has occured while obviously it has not. Is there any sensor to detect if slippage occurs in these motors? Perhaps by the voltage or current...
Hi, we are using Solidworks to create dxf's that our suppliers use for CNC procedures. Problem we've been having with 2007 is some of our suppliers are claiming when they open our files 80% of the lines are doubled up (2 on top of each other) & some radius fillets are missing. Has anyone...
I posted this in the driveline section but then I found this forum which is obviously more relevant -
Hi, I need to cut a timing pulley - metric synchroflex T5 (5mm pitch). Reason is - this size only goes up to 60 teeth off the shelf but we need one that is 72 teeth. So I am after the exact...
Hi, I need to cut a timing pulley - metric synchroflex T5 (5mm pitch). Reason is - this size only goes up to 60 teeth off the shelf but we need one that is 72 teeth. So I am after the exact profile of the tooth so we can design the cutting tool for it. I have profile of the belt tooth, but...
I'm looking for a suitable gasket material for intake chamber.
It is to seal an aluminum surface with a composite surface. Max temperatures will be around 130 deg celcius. The surface of the composite is not machined & is slightly textured so the gasket must deform & seal this region...
Hi, does anyone know how to change the defaults for 'document properties' PERMANENTLY. This includes things like fonts, arrow sizes etc. I see only system options are global, but document prop's need to be changed each time for new docs which wastes a lot of time. Thanks
Hi, I am using the modal dynamics step (linear perturbation)to model the response of a structure with & without damping layers applied to it. I specify the 'material loss factor' by entering the value in the damping, composite section of the material definition. Is this the right way? I assume...
I have been measuring FRF of a structure using a laser vibrometer and electromagnetic shaker. The system has been set up to automatically give the FRF as output variable per unit input of voltage sent to the shaker from signal generator. E.g. Mobility in [(mm/s)/V]. Traditional techniques using...
