Design of the moving part of the wood joint press frame
The thesis includes a description of the company, a description of the area of use of the machine, a description of the programs for failure analysis and analysis of the new or improved frame, as well as the changes made to the structure itself.
In my thesis I will analyze the damage to the wood jointing frame that has been in operation for 15 years. After many years of operation, cracks and thus deformations of the structure itself are formed.
With the fault detection, I started to look for possible solutions that would help to fix the resulting fault or at least improve the new frame.
I helped myself with the Abaqus program, the Autodesk Inventor program, and the Internet. The first step was to use Dassault Systems’ Abaqus program to figure out how and why the frame broke.
The program also showed which parts of the frame are unstressed and therefore also possibly redundant. I came across a few articles on the internet describing them with similar problems and also how they were solved.
In order to make the frame itself as durable as possible, it was necessary to examine each part of the structure separately and thus decide whether to leave it or change it. Consideration had to be given at all times to ensure that the new frame did not introduce any new complications in terms of assembly and work safety.
The gradual change of the framework was made in Autodesk Inventor and then checked in Abaqus, so it was possible to design a new improved and at the same time lighter framework.
Once the design of the new framework was completed, the next step was to look at the technological process of manufacturing the original framework, and then examine what options we have today for manufacturing, since the implementation of the original framework was a long time ago.
In the end, with some changes in the shape and construction of the frame, it turned out that this had a positive effect on the final product itself in several ways. Thus, the new and lighter frame contributes to a longer life of other work attached to the frame itself.
