- W634084732 abstract "Mining operations are alarmed with the current situation of mining equipment tyres, as the demand for these tyres are out numbering the number of tyres being produced. This affects mining operations as they need to conservatively monitor the tyres to ensure that there is no unnecessary down time of machines which in turn affects the maximum production capability. An effective method of extending the life of tyres and preventing premature failure is to ensure that the temperature is kept within a reasonable range as this maximizes the physical resistance to degradation.The aim of this thesis was to determine the feasibility of implementing an effective cooling method onto surface haul trucks. The feasibility of implementing a cooling method for tyres is discussed in numerous different areas with the outcomes identified. The impact of tyres overheating while in operation is discussed with the different consequences listed depending on the conditions imposed on the tyre.It was proposed that a cooling method for haul truck tyres was to integrate the technology of a heat pipe into the tyre. Heat pipes were researched to determine the implications of implementing this method within a tyre as well as the heat transfer capabilities of existing heat pipes. The foremost problem for implementing the heat pipe method was determined to be the nature of the chamber which houses the working fluid. As the tyre will be housing the working fluid and as the tyre is a semi-permeable rubber material this poses a problem as most fluid react adversely when in contact with rubber. The presence of non-condensable gases within the tyre was identified to affect the heat transfer capabilities of the heat pipe method.The appropriate working fluid to be used for the heat pipe method was not found due to the nature of the working conditions. Further research into this area will be required to confirm the physical feasibility of implementing such cooling method.An experimental test rig was developed in light of these findings, to allow for future experimental testing into the heat generation and dissipation with a tyre under loading. The test rig was designed to allow for future experimental studies as it is capable of house a tyre of 900mm in diameter. The total cost of designing, constructing and implementing this test rig was $3686.05 with consisted of $2206.05 for equipment costs and $1480 for constructioncosts.For testing of the temperature distribution through the carcass of the tyre, it was proposed that the use of a thermal imaging camera would be sufficient and a FLIR ThermaCAM P65 was sourced as being appropriate." @default.
