The present invention makes it possible to reduce the volume of communication data necessary for updating the configuration of a circuit unit of a reconfigurable circuit device. In an vehicle control systemincluding an FPGA, the FPGAincludes a circuit unit including a reconfigurable circuit and a circuit SRAM that stores configuration information of the circuit unit. A transfer check unit that acquires a difference command regarding a change part of a circuit element in the circuit unit, and a data conversion unitthat updates the configuration information based on the difference command are provided. Further, in the vehicle control system, a non-volatile memorythat stores the configuration information to be stored in the circuit SRAM is further provided. The data conversion unitmay update the configuration information stored in the non-volatile memorybased on the difference command acquired by the transfer check unit.

In a method for removing a crack in an electromechanical rotor, a through-hole penetrating from a side of one of slots adjacent to each other via a rotor core portion to a side of the other slot is formed to include a crack in the rotor core portion occurring to a contact surface with a wedge, in an electromechanical rotor including a plurality of slots formed in an axial direction in an outer peripheral surface of the rotor core portion, a coil housed in the slot, a wedge inserted in an upper portion of the slot to be arranged in the axial direction and holding the coil in the slot, and the crack is removed.

An object of the present invention is to control crack propagation, either by predicting shaft dovetail crack propagation with high accuracy, or by determining operation conditions under which the crack does not extend. The crack propagation prediction system includes an operation processing unit, an interface unit, and a memory unit. The operation processing unit includes a stress calculation unit that calculates the mean stress generated in the shaft dovetail, a factor range calculation unit that calculates the stress intensity factor range for the crack in the shaft dovetail, and a crack propagation amount calculation unit that calculates an amount of the shaft dovetail crack propagation for an arbitrary time period, from the obtained mean stress and the stress intensity factor range, an operation pattern, an operation time, and data on the crack. The stress calculation unit includes as individual calculation units that calculate separately different types of mean stress, a contact surface pressure stress calculation unit, a thermal stress calculation unit, and a residual stress calculation unit, as well as a mean stress calculation unit that sums these mean stresses.
