“…Literature [19,20] studied sliding electrical contact from contact resistance and friction factor. Some studies [21][22][23][24] explored the sliding electrical contact friction and wear model based on current, speed, temperature and fluctuation frequency. Literature [25] proposed a friction model that can accurately describe motion state.…”

In the marine environment, the working environment of the doubly fed wind generator carbon brush and slip-ring system is complicated, salt spray deposits and seawater erosion affect the temperature field and contact surface friction factor leading to carbon brush wear increase and shortened replacement cycle. The three-dimensional temperature field simulation model of the carbon brush and slip-ring system is established. The main factors affecting the carbon brush and slip-ring system temperature field are sliding velocity, load current, ambient temperature, contact surface condition and contact pressure applied to the brush. Wear capacity of carbon brushes is affected by contact surface temperature. An experimental platform combined with the salt spray test machine was built to carry out the contact current, contact pressure, salt spray concentration and experimental temperature experiment. The improved Coulomb-viscous friction force model was used for the wear prediction model. The sliding velocity, contact pressure, contact current, experimental temperature and salt spray concentration were introduced into the model. The experimental verification has shown that the prediction model can effectively predict the carbon brush wearing capacity under different conditions. This model can be applied to formulating the carbon brush wear amount and replacement cycle in the marine environment reducing operation and maintenance costs.

“…The wear map proposed by Lim & Ashbey [20] was also incorporated into the determination of the curve-fitted parameter in their model. Lin and coworkers [21] modified the Archard wear model by introducing, in addition to mechanical loading, thermal wear caused conducting current, electromagnetic field, temperature field and their coupling effects. The simulated results from COMSOL software were adopted in the integration calculation with the modified Archard model.…”

The metro system of electrified rolling stock is an important vehicle for partly solving the metropolitan transportation and carbon emission problems. This study aims to analyse the wear of current collector/catenary-pantograph system in the rolling stock. A theoretical wear rate model between the conductor wire and the current collector of the pantograph system was adopted from the literature and further decomposed into mechanical load, electrical current, current arc erosion, and the synergy components. Based on the decomposed model, an experimental protocol for finding the curve-fitted parameters for the theoretical model was proposed. The numerical data adopted from a previous literature was employed in the decomposed model to discuss the effects of mechanical loading, electrical current, and vehicle speed on the wear rate components. From the decomposed wear rate model, the so-called electrical current lubrication on the total wear rate due to the applied electrical current could be observed directly. Moreover, the nonlinear couplings among the control factors in the operation of the system manifested significantly. Thus, in the design phase the optimization analysis should be performed on the control parameters using the theoretical wear rate model to extend the life and reliability of this catenary-pantograph system.
