Abstract

This thesis deals with the analysis and investigation of the mill wheel mechanism, a device that uses a hydrodynamic clutch to transfer power from the motor to the grinding wheel. The mechanism is designed to gradually fill the clutch with oil until it reaches operating speed, allowing it to engage smoothly and transfer power efficiently. However, this process presents a problem because the speed at which the clutch can be filled is limited by factors such as power or engine characteristics.

To address this problem, the thesis proposes a solution that involves the use of numerical integration of the equations of motion to determine the optimum speed at which the filling process can take place. Specifically, the equations of motion of the control mechanism are discretized and solved numerically using a computer program written in Visual Basic. The program uses an integration step size that can be varied to ensure accuracy and automates iterations of the calculations from zero to maximum filling of the hydrodynamic coupling.

The initial results obtained from this procedure are then further optimised using the aforementioned program, which is repeatedly used to determine the minimum filling time of the hydrodynamic coupling. This approach provides an automated solution to the problem that avoids the need for manual calculations.

Overall, the aim of this study is to provide insight into the rate at which a hydrodynamic clutch can be filled and to offer a practical approach to optimising this process. By automating the calculations and investigating the influence of various parameters, the work aims to contribute to a deeper understanding of the grinding wheel mechanism and provide information for the design of more efficient and effective power transmission systems.
