Hi,
I'm trying to make an animation of a cylinder following a path however have been unable to encourage the cylinder to move. Please can anyone help me with how to set up the motion simulation?
I've modelled the path as a surface. I've constrained the edge of the cylinder to the edge of the...
Hi,
I'm trying to simulate a cylindrical part being forced into contact with a flat surface and would like to apply a bearing load however I can't find the function in my version of CATIA. I have no bearing load option in my loads toolbar. Is there another way of creating a sinusoidal load...
Hi,
I'm using dynamic sectioning in Part Design and have inadvertently changed a setting so that I now see the inside and outside surfaces but not a solid "cap" coloured green as it was previously set. This allows you to see right inside the part but is confusing. Can anyone tell me where the...
Hi,
I'm doing some check analysis on a cylindrical housing under external pressure (subsea); the radius / wall thickness ratio is approximately 8.
I have the capability to do static FE analysis which will predict stresses however I'm not convinced that if I compare these with material yield...
Hi,
I have a component made from Delrin (Ertacetal) which has failed; I suspect the failure is due to fatigue driven by vibration. I've looked at the failed surface under a low magnification microscope and there appears to be what looks like "beach marks"; as the material is white plastic these...
Hi
I work in the UK and produce drgs to BS8888. I'm looking into whether we can use the SolidWorks hole tables without further modification. I don't think the symbols SolidWorks uses for CSK, CBORE, DEPTH etc are used in the BS spec? Does anyone in the UK use these symbols and if so how do...

Hi,
We are being asked to manufacture a special stud which was originally made from Aluminium Bronze to "NC Ashton 93/7 Cu/Al + Tin + Cobalt". The material is no longer available. Does anyone know of a direct equivalent or have any mechanical property data for this material?
The stud is used...
Hi,
Can anyone tell me if NX is available to run natively on Mac OS yet please? I asked my UK reseller and he didn't know anything about it. Previous threads on this forum from 2007 suggest that it was planned. If so, how does it run in comparison to Windows versions?
Cheers
Hi,
I'm an experienced NX user just starting out with SW. I'm used to re-naming parameters in NX and then using them in expressions such as "Length = Width/2". Can I do something similar to this in SW please?
Cheers
I'm looking for some help please regarding the UK steel 826M40 condition Y, formerly En 26. The material properties listed are 0.2% proof strength 1080 MPa and UTS 1225 MPa. I need to know whether this material is considered to be brittle or ductile as I am trying to determine a suitable safety...
I'm aware of the need to lubricate bolts on assembly to reduce the scatter on preload. Is there a particular lubricant type or viscosity recommended please?
Thanks

Please can anyone help with using Hertz contact stresses? I am designing some equipment for a customer who requires I use a safety factor of 4 on proof strength and 6 on ultimate strength. This is fine when it comes to bending and shear stresses etc, however I'm not sure "what to do" with Hertz...
Is there any data published on shear capacity of plain dowel pins eg BS 1804 or EN ISO 8734? These standards give hardness values but no indication of shear strengths or load capacities. I have estimated a shear capacity using a formula for hardness vs tensile strength but am not sure how...
