    Electroplating thickness and composition tolerances

    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...

    Cast Iron EN-GJS-400-18LT

    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...

    Contact ratio between two surfaces

    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...

    Thermal - Displacement calculation

    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...

    Brake pad-disk temperature distribution

    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...

    Screw thread simulation with ansys

    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...

    Welding acc. to Eurocode

    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...

    Steel structures

    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...

    Cam and Follower in ansys

    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. https://www.youtube.com/watch?v=9hVgctcI3-Y Thanks in advance.

    L shape beam

    Hello, Im trying to design a casted component with the following shape. As expected, I find high stress on the corner and a radius can reduce them. My question is: If the maximun stress on the radius is higer than yield strengt, in static: It will "plastify" a little and this high stress...

    Welding dimensioning

    Hi all: I'm designing a steel structure. This structure consist on welded steel plates (with different, but similar thicknes). My main issue is that I find a lot of probles while dimensioning the thicknes of weldings. I made a "hand calculation" of the forces in the position of the...

    Creo Elements and Welding (FEM)

    Hallo, I'm mechanical engineer and I work with Creo Elements (and Pro Mechanica) for FE calculations. Now I would like to include in some of my calculations welded connections, but I fond some issues. I can introduce the weldings, with the addecuate thickness and material, howeve, i can't...
