Introduction With the reduction in reserve and a raising demand for energy and the increasing seriousness of environmental pollution, it is very necessary to find alternative raw materials to petroleum [1].Biomass material is recognized as an important source of renewable and alternative raw materials[2], because its rational use does not contribute a net rise in the level of CO2 in the atmosphere, and it is the only renewable source of fixed carbon that can be converted into liquid, solid and gaseous fuels [3].

Research on the simulation and calculation of the temperature field of friction plate in brake is one of the main references for constructing a frictional material couple.
Research on the simulation and calculation of the temperature field of friction plate in brake is one of the main references for constructing a frictional material couple.
For analyzing the temperature field conveniently, it is assumed that: (1) the friction heat flux transfers along the axial and radial direction; (2) the coefficient of friction remains constant during braking; (3) the brake pressure is uniformly distributed over the contact area of the plate and mating plates; (4) the materials of the friction plate are homogeneous and their thermal properties are invariant with temperature; (5) the thermal properties of lubricant oil are invariant with temperature; (6) the temperature field is consecutive and heat flux is constant; (7) the radiation is omitted.
