Static and Dynamic Seal Friction in High Performance Hydraulic Systems

Gresham, David Raymond (2017) Static and Dynamic Seal Friction in High Performance Hydraulic Systems. [USQ Project]


The purpose of this study is to develop a test rig representative of the contact surfaces within the Russell Mineral Equipment (RME) THUNDERBOLT High Performance Hydraulic Hammer. To observe and measure the frictional forces resulting of the tribological phenomena occurring, in order to determine the amount of energy lost within the system. No system is perfect, there is a quantifiable energy loss within the 1500 and 750 model THUNDERBOLT Hammers. Due to the complexity of the system, this investigation focuses on the seals and the friction they produce.

After conducting a thorough literary investigation, an iterative development process was applied to develop, evaluate and improve varies iterations of the proposed test rig. This process extended to the entirety of the projects components, i.e. Drive systems, safety elements and support structure.

The outcome of this project has been the development of the proposed test rig, though due to time constraints the testing procedure has not been conducted. The testing procedure will be conducted at a later date, within the scope of future work. In place of the analysis of experimental data, extrapolated data sets from T. Papatheodorou 2005 are assessed. This data was originally utilised to predict the expected friction and develop the test rig system. This data is expected to overestimate the friction the THUNDERBOLT hammer sees as there are a number of discrepancies between the two systems. The main variances include the type of seal utilised and speeds at which the system operates.

Despite the discrepancies and assumptions, the data suggested energy loss within the expected range. Recommendations for future work include the validation of the analysed data through testing, refinement of the system to better replicate the THUNDERBOLT Hammer and wear testing of the system components.
