Prototype of 3D printed mecanum wheel

Mateja Krzysztof

Technical Sciences / University of Warmia and Mazury in Olsztyn

2023

This article presents the results of work related to design, analysis and selection of the 3D printed mecanum wheels. Initial CAD model does not include material type of the rollers. Rollers were printed in 4 types of filament: PLA, ABS, PETG, FLEX. Analysis, tests and target destination of use allowed to choose the best material for rollers which will meet the usage requirements. Next step after choose material for roller were assembly of the wheels. Wheels were tested on the simple platform. Assembled 4 wheels (two left and two right) allowed to carry out tests to verify the mobility of the mobile robot and check the adhesion between rollers and ground.

Developing a test site for testing the suspension of vehicles with omnidirectional wheels

The paper presents a test site for determining the excitations that occur as a result of the contact between the omnidirectional wheel and the road and affect the single suspension column in motor vehicles. The specific nature of these excitations during the movement of omnidirectional wheels is caused by the irregular envelope of the wheel. The proposed test site enables to determine the vertical displacements of the wheel that is rolling along the paving of the road. The conducted experiment demonstrates that the test site was constructed correctly.
