Experimental Study of the Strength of Triangle Model Connections on the Gorlov Turbine Multi Assignment

Abstract

This study was carried out to justify the strength of the connection of two or multiple Vertical Axis Water Turbines (VAWT) with a diamond bond model using laboratory and field studies. This study is very important because it is intended for joints, where the load occurs dynamically between two vertical axis water turbines placed on the water flow. The connection must be able to accept the heaving, pitching and yawing loads that occur when the turbine is subjected to hydrodynamic loads. Wood, which is receiving increasing attention in the green and sustainable building industry, is starting to be mechanically positioned according to its strength. For this reason, in this study, wood was chosen as the main material in side loading between the Gorlov Turbine samples. The test is carried out by making a tickblock model which is coated with a glass composite which is then given a load, and measuring the deviations that occur. Prior to the test, a Finite Element Methods test was carried out to determine the deflection due to the working load, in the form of thrust force and torque moment. From the tests carried out, it was obtained information that the joints provide stiffness that can be approximated by the quadratic model. Tests on the scale of the Gorlov turbine model have also been justified in experiments which have shown satisfactory results. The torque generated is quite adequate, which is around 17.83 Watts at 100.2 rpm. From this test it was found that apart from torsional motion, other movements can be minimized so that the effect of aeroelasticity phenomena can be avoided.
