摘要： PROBLEM TO BE SOLVED: To provide a calculation method of torque with which trouble for creating a multidimensional map can be saved, an inexpensive configuration is made by a minimum input value, calculation is realized with an ECU level of a small scale and precision required for engine control can be obtained by simplifying respective losses, deriving a formula, and performing calculation by it. SOLUTION: In a Lundell-type synchronous generator, only power generation output current and the number of rotations are set as inputs. Electric energy and a loss amount are calculated from power generation output current and the number of rotations. Power generation torque is calculated from a total of electric energy and the loss amount, and torque is outputted as a result. Only output current and the number of rotations are set to be calculation inputs in the formula. Thus, calculation time is shortened as minimum input. COPYRIGHT: (C)2007,JPO&INPIT

摘要： PROBLEM TO BE SOLVED: To establish a method for designing a rolling bearing by taking into consideration of the brittleness exfoliation to solve the mechanism of the generation of the white layer in the rolling bearing. SOLUTION: The white layer is an unstable plastic phenomenon caused in a high speed deformation state. In this case, the material of the rolling bearing is left in an adiabatic shear deformation state. As a result, an adiabatic shear band is produced inside the material, and the brittleness exfoliation of the bearing is early caused. The bearing causing high speed deformation is subjected to the condition shown in the following expression; Δγ 2 /sec (Δγ expresses therein the primary differential to the time 8), and further a condition for causing the unstable plastic phenomenon based on the following expression; γ c , where γ is a true shear strain caused in at least one component, and γ c is a critical shear strain depending on the property of at least one component, and a step for judging that there is no possibility of the generation of the adiabatic shear band, and as a result, the brittleness exfoliation does not occur when at least one of the two conditions for causing the high speed deformation and the unstable plastic phenomenon is not satisfied.
