Comparison of Slips and Pulling Forces on Worn and New Tyres
نویسنده
چکیده
Original scientific paper The slip, the resistance to rolling and pulling force are interconnected. The influence of tyre wear on the tractor pulling force and slip on three different grounds was observed. The tangential force was measured by dynamometers fixed to tractor driving half-axle. The pulling force on the pulling rods was measured by dynamometer fixed to the pulling force. The tractor was braked under control by the vehicle in which the measuring instruments were placed. The slip was measured by means of the fifth wheel. The measurements were carried out on the AGT 835 T tractor with diagonal tyres of Ruma Guma make 7.5 – 16. The tyre wear amounted to 46.7 %. In the case of tyre wear the differences are rather small or even do not occur. When using new tyres a 3 to 5 % smaller slip was observed during plowing. On the asphalt greater tangential force was observed when using worn tyres. On the grassland where maximum pulling forces were observed there were no differences between worn and new tyres.

SIMULATION AND MONITORING OF THE MACHINING PROCESS VIA FUZZY LOGIC AND CUTTING FORCES
On time replacement of a cutting tool with a new one is an important task in Flexible Manufacturing Systems (FMS). A fuzzy logic-based approach was used in the present study to predict and simulate the tool wear progress in turning operation. Cutting parameters and cutting forces were considered as the input and the wear rate was regarded as the output data in the fuzzy logic for construct...

Non-Singular Terminal Sliding Mode Control of a Nonholonomic Wheeled Mobile Robots Using Fuzzy Based Tyre Force Estimator
This paper, proposes a methodology to implement a suitable nonsingular terminal sliding mode controller associated with the output feedback control to achieve a successful trajectory tracking of a non-holonomic wheeled mobile robot in presence of longitudinal and lateral slip accompanied. This implementation offers a relatively faster and high precision tracking performance. We investigate this...
متن کاملPsychophysical basis for maximum pushing and pulling forces: A review and recommendations.
The objective of this paper was to perform a comprehensive review of psychophysically determined maximum acceptable pushing and pulling forces. Factors affecting pushing and pulling forces are identified and discussed. Recent studies show a significant decrease (compared to previous studies) in maximum acceptable forces for males but not for females when pushing and pulling on a treadmill. A co...
