Hello everyone,
we get a request to electroplate some steel components according to ISO 15726.
In our request, thickness is defined as 10um.
ZiNi porcentaje is also set to 12% Nickel.
I checked the standard and I’m not able to find any tolerance to these values.
I can’t also evaluate the...
Sorry, I think my explanation was not the best.
All the critical stress are tensile stress on roundings. The component has not critical compression stress.
Hi all!
I´m calculating a component with GJS-400-18LT cast iron. This component works with low dynamic loads, but it has to whistand a high loading (static) during the assembly.
The component has some big cylindrical holes with rounded corners. These holes recieve axial load, that produce...
Sorry, perhaps my explanation was too simple.
I have two plates in contact, both with quite good surface quality (Rz=6-10). Im expecting detailed values.
One of the plates will be hot and the other one cold. To make a very rough estimation of the heat transfer resistance, I would like to know...
Hi folks,
I would like to know if there is any equation or similar to define the real contact ratio between two surfaces.
For example, we can consider two steel surfaces with a defined Rz in contact. The real contact will never be 100%, as there will be micro gaps. If we improve the Ra (and...
Hello all,
I would like to simulate the temperature distribution of a braking process with Ansys.
The idea is to have a rotating disk with two non-moving pads on it. The heat will be added a an external value on the brake pads and the disk will reduce its temperature due to convection.
It...
Hi there!
I would like to calculate the temperature developement of a brake system; this means brake pad in contact with brake disk.
I can calculate the dissipated power during the braking, as well as the convection on the disk depending on the rotation speed. However, I´m no sure about the...
Hi all!
I´m trying to simulate the tightening of a screw. It sounds easy, but I can´t get any result.
First, I have created a 3D file with a screw and a long nut (see picture).
The outer cylinder with the thread is fixed.
The plate between schre head and thread is also fixed.
The total...
Thank you for the Information.
ENV seems to be a Kind of pre-standard. As I´m doing a first approach to this calculation I guess this will be ok. Later can I go more in detail.
If target is 100k cycles, you do not need to take fatique into consideration.
Which would be then the Limit to...
Eurocode 3.
However if any additional Standard helps to calculate welding, it is not a Problem to use it. I used the Eurocode because is the Standard that I have right now.
Hi everyone!
I´m trying to calculate an easy welding Connection between two plates according to the Eurocode. However, I have some questions about the process.
Enclosed is the file (.pdf) with the calculation. This is a very easy example. It would be very nice is someone could take a look to...
Hello!
I´m designing some steel structures to support some brakes.
This structures consist on welded steel plates (aprox. 20mm thickness).
At the beginning, I did some analytical calculations to dimensions them. However, the structures are more and more complicated and hand calculations are...
Hello to all,
At this moment, I would like to simulate the contact of a cam with the follower in ansys transient structural. I´m not able to find any option for this contact.
In this video it is possible to see clearly what I mean.

Thanks in advance.
