Abstract [sv]

Marinediesel has, to meet there customers needs for a suitable sterndrive to powerboats, developed a prototype. The prototype is currently in the testing phase. The opportunity to test the sterndrive under load inside the workshop has not previously been possible. Until now the drive has been tested in a test bench without any load on the propeller axle. The prototype has also been tested under real conditions mounted on a boat.The idea with my thesis was to create a test bench that can run around the clock in order to be able to test things like wear and service intervals and other things that require that the test interval is long. In this report, I have deepened me in how to measure the torque on a rotating shaft. This specialization has led to that the torque is not measured directly on a shaft. Instead the torque is calculated from the oil pressure in the hydraulic cylinders which manages the application of simulated resistance of the propeller shaft. This simulated resistance is created by hydraulic cylinders, belts and pulleys that are stretched and released depending on the desired clamping. The output and input signals is handled by a PLC with integrated touch screen. The choice of mechanic drive finally ended with an inverter drive controlled asynchronous motor of 75kW. In this report there is also a piece about some ways to reduce the unwanted noise that occurs with inverter drives. Enjoy the reading.
