Static Experimental to Justify the Vibration of the propeller shaft due to its unbalance

This paper reports the mass imbalance in a propeller studied theoretically, experimentally, with blades made of aluminum. These propellers have been used in aircraft engines to generate thrust and for other needs, for example as a force generator for aircraft maneuvering needs. This research was completed using a half car model running on a rough track to model heaving and pitching movements. Modeling these imperfections, in this research to model an imperfect propeller shaft. A rough path in the bearing contact path is a source of excitation that causes vibration to occur. In this research, information was obtained that with wear on rolling bearings, the frequency response will produce harmonics at higher frequencies. In the propeller shaft model, the shaft modeling is similar to using a 4 degrees of freedom half car model. However, the excitation comes from an unbalanced propeller. In this case the propeller will be used as a test tool which rotates at 100 rpm. This is to provide the ability to balance statically and/or dynamically or use IoT. The vibration response is obtained by simulation in the software. If such maintenance equipment is available, and all conditions of bearing stiffness, damping and mass are in a state of precise determination, then the teaching becomes more perfect. The research helps aircraft mechanical engineers determine vibration response. Our dynamic propeller laboratory dreams of creating a lab. Static and dynamic with controllers using IoT
