Abstract [en]

The division of Engineering Materials at Linköping University, department of Management and Engineering, conducted a research project concerning Fatigue life of thermal barrier coatings during 2009. During this project equipment to provoke these fatigue failure by rapidly heating and cooling test subjects in cycles, was ordered.

Design and manufacturing of the equipment was handled internally at LIU.

The equipment was built using a furnace that is lowered and raised over the table where the test subject is placed. To keep the temperature of the furnace a lid slides in place to close the downward facing opening of the furnace when it is in the raised position. On this door there is nozzle that is used to cooling of the test subject by air.

To make sure that the equipment can work independently you need an automation controller that can evaluate if movement can occur without danger of collisions. The control system also needs to monitor that all elements are performed according to plan.

This degree project is based on a modular system from OPTO 22 and includes the configuration of a PLC that will be supplied with logic and a user interface.

The degree project resulted in a graphic interface in which a user can set desired values for different parameters and get information about current values for them. Using the interface the user could also start and stop the running of cycles. An analog interface consisting of a start and stop button is also handled in the project.

Logic has been created and tested using simulations of incoming signals. During these tests it managed to transform the equipment from standby to starting position for running cycles, running cycles that can be adapted by the user and to put the equipment in standby position when the user want to power down the system. Apart from this there is also routines to monitor that movements is actually done according to plan and communicates with external systems capable of sending signals. A routine that both transform digital alarms and translate numerical values representing different choices to text messages in the graphic interface has been created.
