Pre-study, development, manufacturing, and evaluation of a Pin-on-Disc machine (tribometer) which can measure friction in the contact while changing speeds and pressures in a short time interval.
During tightening of a screw, the variation in friction will affect the force acting on the joint, especially when tightening using torque as a control parameter. Since friction is such an important factor when aiming for a specific clamping force, it is of interest to simulate the contact and friction in the screw head to joint, and thread interfaces. This will lead to a possibility of gaining a deeper knowledge of friction characteristics when tightening, and how the dynamic friction relates to different coatings/materials and screw geometries. In the end, understanding friction behavior will make it possible to influence the quality of the assembly.
To develop and evaluate different concepts of a pin-on-disc machine based on their merits. Choose the best possible design which fulfills the specifications. Using FEM to evaluate the design. Produce relevant manufacturing drawings of different components and assembly of the Pin-on-Disc machine. Collaborate with another master thesis students working parallel with the design for the control system of the Pin-on-Disc machine.
