The main purpose for mechatronic concept designing is validating the operational performance of any machine or system. Creating a simulation in a virtual environment is a safe and cheap method for validation and brings up possible errors that could cause significant economic losses if the error occurs in a physical test build, or in the final product.
In this report the steps of building a digital twin is brought out from a physical automated roundtable, commissioned by Höhere Fachschule Technik Mittelland. The goal of the work is to create an identical roundtable in virtual environment and reach a level of functionality to where Swiss students can use it as a learning method. The report follows the steps in the same order as the table was being built in the digital environment. In this report the work is simplified into smaller sets to help understanding the structure and methods used in the digital twin. The project begins with listing down the features and behaviour of the physical roundtable and continues dividing it into smaller sets. The work is done in 3 phases which are CAD-modelling, assembly and mechatronics concept designing. Since the product is a large and complex automated roundtable with 6 stations, each station is separated into its own sub-project, and they are built in a consequent order.
As a result, all design and assembly were finished, and the mechatronics concept was simulated successfully in siemens NX. The digital twin was able to perform the same actions as the actual roundtable, but in the digital environment it was not necessary to add safety indicators and kill switches. Because of the lack of those indicators, the output data from the digital twin to the pro-gram was not fully identical with the actual roundtable output data. Therefore, simulation was performed along with the actual roundtable. However, a simplified program was created for the first station to give the students an easy approach to understand the principles and use this project alone in digital environment for learning purposes.
