Abstract: Research on a tubeless tire for a light vehicle. Master’s thesis / Les A.O., Zinko R.V. (head). Department of Machine Design and Automotive Engineering, Lviv Polytechnic University. Lviv, 2022. – 45 c. - 10 Bibles - 4 sheets c. often The loss of air pressure in a pneumatic tire of a traditional design inevitably leads to the suspension of the motor vehicle, and at high speeds - to a traffic accident with serious consequences. For military vehicles, this problem is particularly relevant, since in combat conditions, a stationary car is the most vulnerable to grenade launchers and small arms fire. The level of the modern chemical industry makes it possible to create fundamentally new designs of airless wheel drives that have increased resistance to mechanical damage and at the same time are not inferior to traditional pneumatic tires in terms of performance. The purpose of the work is to study the operational properties of airless tires. To achieve the goal, the following tasks were solved: 1 Analyze the existing designs of airless wheels. 2. Carry out mathematical modeling of tubeless tire processes. 3. Investigate the strength properties of an airless wheel. 4. Investigate the temperature properties of an airless wheel. 5. Investigate the operational properties of an airless wheel. The subject of the study is the influence of design parameters on the operational properties of an airless wheel. Research methods. Use of calculation methods for complex technical systems, experimental studies, finite element method. The scientific novelty of the obtained results is as follows: - a methodology for researching the operating properties of an airless wheel has been developed.
