EHD-HS
The EHD-HS allows research at high operating speeds, exceeding the point at which standard film-thickness equations break-down.
Tribology has been an essential part of the development of improved powertrains for decades and—even with a growing shift to electric vehicles—this continues to be the case today.
The powertrain of a vehicle encompasses every component that is involved in the conversion of power to movement. This is true for any sort of vehicle, from boats to planes and cars to bikes, although each of these will have very different requirements placed on powertrain components. However, one thing all will have in common is that they will consist of many moving parts that are in near-constant contact with other components. It is in these contacts—found in any powertrain—where tribological research has been focused to continually improve and optimize designs.
PCS's range of instruments is used extensively by industry and academia to achieve this continual improvement. The MTM and ETM are key tools used for this work. Both have independently driven specimens that enable a wide range of contact conditions to be replicated and together cover an impressive range of contact pressures from close to 0 to 3.5 GPa with standard specimens, and even more with nonstandard specimens. This versatility means that researchers can use these instruments to investigate all the different contacts you would find in a whole host of powertrain applications, investigating wear, friction, and film buildup. The EHD is also extensively used in this area for investigating film thicknesses and traction coefficients of lubricants found in these systems; and the MPR is used to investigate how parts and lubricants will stand up to prolonged use over the years.
As an area of significant power wastage in vehicles, powertrains have always been of interest to tribologists. This interest will only continue to grow, as the frictional losses in the powertrains of electric vehicles are a larger portion of total losses than in internal combustion engines. As such, powertrain research and developments that tribology can bring are only going to become more important in the future.
The EHD-HS allows research at high operating speeds, exceeding the point at which standard film-thickness equations break-down.
The ETM offers the capability investigating the effect of lubricant formulation on surface damage and traction in heavily loaded transmission contacts.
The HFRR enables value research into the fundamentals of wear failures in powertrains such as fretting.
Research into transmissions operating in harsh environments and at elevated pressures can be effectually achieved using the HPR.
The HSD enables the development of effective solutions for the challenges around maximising performance and reliability of high speed transmissions.
Research on the MPR on transmission machine elements is critical in order to minimize power losses and maximize fatigue lives.
The MTM allows fundamental investigations into the behavior of a lubricant's chemistry and surface interaction within tribological contacts in transmissions.
Electric motor driven powertrains are increasing the performance demand on tribological contacts through the introduction of electric potentials the challenge of which can be overcome through research using the MTM-EC.
