Master's Theses (2009 -). 443. http://epublications.marquette.edu/theses_open/443 PERFORMANCE ANALYSIS OF A CONSTANT SPEED LOCAL OBSTACLE AVOIDANCE CONTROLLER USING A MPC ALGORITHM ON GRANULAR TERRAIN by Nicholas Haraus, B.S.M.E. A Thesis submitted to the Faculty of the Graduate School, Marquette University, in Partial Fulfillment of the Requirements for the Degree of Master of Science Milwaukee, Wisconsin December 2017 ABSTRACT PERFORMANCE ANALYSIS OF A CONSTANT SPEED LOCAL OBSTACLE AVOIDANCE CONTROLLER USING A MPC ALGORITHM ON GRANULAR TERRAIN Nicholas Haraus, B.S.M.E. Marquette University, 2017 A Model Predictive Control (MPC) LIDAR-based constant speed local obstacle avoidance algorithm has been implemented on rigid terrain and granular terrain in Chrono to examine the robustness of this control method. Provided LIDAR data as well as a target location, a vehicle can route itself around obstacles as it encounters them and arrive at an end goal via an optimal route. This research is one important step towards eventual implementation of autonomous vehicles capable of navigating on all terrains. Using Chrono, a multibody physics API, this controller has been tested on a complex multibody physics HMMWV model representing the plant in this study. A penalty-based DEM approach is used to model contacts on both rigid ground and granular terrain. -

The Effect of the Tractor Tires Load on the Ground Loading Pressure
ACTA UNIVERSITATIS AGRICULTURAE ET SILVICULTURAE MENDELIANAE BRUNENSIS Volume 65 165 Number 5, 2017 https://doi.org/10.11118/actaun201765051607 THE EFFECT OF THE TRACTOR TIRES LOAD ON THE GROUND LOADING PRESSURE Lukáš Renčín1, Adam Polcar1, František Bauer1 1 Department of Technology and Automobile Transport, Faculty of AgriSciences, Mendel University in Brno, Zemědělská 1, 613 00 Brno, Czech Republic Abstract RENČÍN LUKÁŠ, POLCAR ADAM, BAUER FRANTIŠEK. 2017. The Effect of the Tractor Tires Load on the Ground Loading Pressure. Acta Universitatis Agriculturae et Silviculturae Mendelianae Brunensis, 65(5): 1607 – 1614. The contribution, based on the experimental measurement, analyses the issue of a specific pad loading pressure in relation to radial wheel load and tire inflation. Tile inflation in terms of allowed radial load, which we wish to be high as far as possible in terms of the power transmission from the wheels to the ground is important for the field tensile works, on the other hand, the pressure in the tire is closely related to the contact area and ground loading pressure. The obtained results show the following: Michelin Multibib 650/65 R38 tire, inflated to a pressure of 80 kPa has a sufficient reserve in radial load. As the measurement results show, ground loading pressure at the highest load of 36.55 kN, which was used during the measurement, is under the value of 100 kPa, which would mean on loamy soil at a humidity of 17 % that the limit of the ground pressure on the ground has not been exceeded. Keywords: stress transmission, tire inflation pressure, area of imprint, pressure in area of imprint layer. -

Design of a Portable Tire Test Rig and Vehicle Roll- Over Stability Control
Design of a Portable Tire Test Rig and Vehicle Roll- Over Stability Control Derek Martin Fox Thesis submitted to the faculty of the Virginia Polytechnic Institute and State University in partial fulfillment of the requirements for the degree of Master of Science In Mechanical Engineering Approved Saied Taheri, Chair John B. Ferris Disapproved Mehdi Ahmadian Presented on December 9, 2009 Danville, VA Keywords: Portable Tire Test Rig, Vehicle Rollover Mitigation Techniques © 2009 Design of a Portable Tire Test Rig and Vehicle Roll-Over Stability Control Derek Martin Fox Abstract Vehicle modeling and simulation have fast become the easiest and cheapest method for vehicle testing. No longer do multiple, intensive, physical tests need be performed to analyze the performance parameters that one wishes to validate. One component of the vehicle simulation that is crucial to the correctness of the result is the tire. Simulations that are run by a computer can be run many times faster than a real test could be performed, so the cost and complexity of the testing is reduced. A computer simulation is also less likely to have human errors introduced with the caveat that the data input into the model and simulation is accurate, or as accurate as one would like their results to be. Simulation can lead to real tests, or back up tests already performed. The repeatability of testing is a non-issue as well. Tire models are the groundwork for vehicle simulations and accurate results cannot be conceived without an accurate model. The reason is that all of the forces transmitted to and from the vehicle to the ground must occur at the tire contact patches. -

Tyre Ageing kimberleygroup.com 3 Importance of Optimum Tyre Pressure and Temperature This eBook addresses the question: How much of Australia do you want to experience? kimberleygroup.com 4 Importance of Optimum Tyre Pressure and Temperature Why is Tyre Pressure so crucial? Your tyre’s inflation pressure is measured as pounds per square inch, (psi) or “Bar (metric). The maximum recommended psi for your tyres printed right on them. However, manufacturers may print a lower recommended psi than your tyre can truly handle because the lower inflation rate will give you a softer ride. If you over inflate your tyres, you might cause some safety hazards. You’ll definitely wear out the tyres more quickly. A tyre that is over inflated shows more wear along the center width of the tyre than along its edges. When your tyres develop uneven tread wear, it shortens the overall life expectancy of your tyre.
