“…The tyres are larger and subjected to much greater loads than automotive tyres, and the need to simulate an aircraft during take-off, landing or for taxiing manoeuvres has led to specialised aircraft tyre models. 8 A number of tyre models have been developed for the simulation of vehicle handling over recent decades. Of these, the most widely used model is that developed by Pacejka and Bakker.…”

“…Examples include the NASA facility in Langley, Virginia 18 and the Airbus TerraTyre test facility in Toulouse. 8 It should be noted that with a truck or trailer based test rig the vehicle must be large enough that the test tyre does not affect the trajectory of the driven vehicle, as it is this trajectory that dictates the test conditions for the tyre.…”

This paper describes a programme of tyre tests using a purpose built tyre test rig designed specifically to investigate the behaviour of tyres that are used with Road-Rail Vehicles (RRVs). These vehicles are used extensively by the rail industry to support the maintenance of existing rail lines and new construction works. In many cases, using a vehicle that can only operate on the road, or a rail engine that can only operate on tracks will not provide a suitable or effective solution for the task in hand. RRVs are able to operate on both roads and rail, and as such provide a very flexible solution to the rail industry. When operating on the road, RRVs use pneumatic tyres to control their motion and act to all intent and purpose as a normal road vehicle. When operating on rail lines RRVs use a combination of the pneumatic tyres and standard steel rail wheels to control their motion. The rail wheels maintain the directional stability on the track and the pneumatic tyres provide the tractive force to drive and brake the vehicle. Unlike standard road or rail vehicles, there is to date no predictive engineering practice that allows the use of computer simulation to design and optimise the performance of RRVs when they are operating on rails. Computer tools, such as multi-body systems (MBS) analysis are used extensively to design both road and rail vehicles. For road vehicles a tyre model is needed to represent the behaviour in the contact patch between the tyre and the road. For rail vehicles a model is needed to represent the contact force between the train wheel and the track. In both these applications the behaviour is well understood and over the last half century mathematical models have been developed that allow accurate and useful simulation to support the design of new vehicles and trains. In contrast, RRVs have evolved essentially as modifications to standard road vehicles. While the base vehicle may be very well designed to perform on the road, the performance on rail is based on experience and some testing. There is no up-front science involved in designing a RRV to perform effectively during this very important phase of its operation. In order to develop an accurate model to predict RRV performance on rails it is clear that a model of the behaviour of the tyre when in contact with the rail is needed. To date, no such model exists and additionally the testing needed to generate data that could be used to develop a model has never been carried out. The work described here addresses this with the design and build of a unique test rig that can be used to test tyres on rails for a range of operating conditions, and produce a set of initial results that provide a framework for a future tyre/rail model. The paper concludes with a review of the behaviour measured and provides new insights into how well tyres perform on rails and also where the behaviour differs from the well understood behaviour of tyres operating on roads. The important behaviours that would provide the main parameters for a new empirical tyre model are also identified and discussed.

“…Korunović et al consider the symmetrical case of airplane landing [7] (i.e., it is assumed that both tires simultaneously contact the runway) in order to analyse the deformations that occur in a tire during this case of landing. Differently from [8], this study analyses only the moment of landing, i.e., the moment of contact of the tire with the runway. As the contact time is very short, it is assumed that at this moment there is no increase in temperature in the tire, which is contrary to studies [9] and [10], in which the thermomechanical behaviour of an aircraft tire in critical situations is studied.…”

A New Design Solution for Aircraft Wheels that Reduces Overpressure in the Tire while Retaining its Absorption Power and its Dimensions

It is well-known that high working overpressure in a tire adversely affects its service life, while a lower overpressure requires larger tire dimensions and weight. The goal of this research is to find the way to decrease the overpressure in a standard tire in order to increase its durability, while preserving or increasing its load-capacity and retaining the same geometric characteristics. This paper presents a new construction solution that consists of a standard (outer) tire and a smaller (inner) tire inserted in the standard one. This set of tires creates a unique kinetic energy absorption system that occurs when the aircraft lands in direct contact with the runway. During the aircraft hard landing, a large deformation of the tire occurs, i.e., the tire surface is drawn inward both in the cross-section and in the longitudinal section. In this case, the whole weight of the airplane is directed on the tire-shoulder, meaning that the actual contact surface is small. In the new solution, the inner tire prevents the standard tire from drawing inward and keeps it in contact with the runway during tire deflection. A comparative analysis of the change in deflection, track width, and stress distribution of a standard tire and a set of tires in the new solution is performed. It was shown that the new construction solution increases the tire track width by about 8 % and, therefore, the greater contact area between the tires and the runway. In addition, tire stress is decreased by about 40 %; therefore, it has higher tire durability, as well as the ability to absorb more kinetic energy by 56 % compared to a standard tire.

“…Another is based on geometric model (Koutny, 1981), minimum energy principle was used and the force balance was not involved, it was much simple with respect to physical models. The third was based on finite element model, and it has been applied to analyze tire successively (Ghoreishy, 2008;Wood et al, 2012). The equations obtained by different methods are various, most of them are very complex, and they are not convenient and intuitive to be used for designing tires.…”

Tire performances are strongly influenced by cross section profile, and equilibrium profile has been a focus of radial tire researches, however, how to use the profiles to design radial tires has been reported rarely due to reasons of secrecy. This paper describes a practical method of using equilibrium profile to design radial tires, which is based on the restricted dimensions by tire standards. Based on the membrane model and minimum energy principle, equations of equilibrium profiles of radial tires with flat and curved belts are obtained by using variational approach. A method of designing carcass contours by using these equations is developed, in contrast to earlier methods the proposed method makes the width rather than the height of the point with maximum width on the profiles as the input parameter, and the restriction lengths of carcass by the belt are also calculated at the same time. For 175R14 tire, this paper's results are compared with Akasaka's, the accuracy of this method is confirmed and the effects of belt radius on profiles are revealed. Four different designs of 295R22.5 tire are analyzed by finite element method to verify the benefits of this method. This method can be used to design both tires with larger and smaller aspect ratios, and it will offer a strong guide for designing radial tires.
