<P>PROBLEM TO BE SOLVED: To solve the problem that acceleration torque or the like in a rotor consumed in a motor cannot be accurately calculated and the lifetime of a reduction gear cannot be accurately calculated when a friction coefficient varies due to a temperature change or aging. <P>SOLUTION: Torque operating on machine elements from junction displacement converted by a junction displacement/speed/acceleration operation part 4 is calculated, and operating speed in the machine elements is calculated, thus evaluating the lifetime of the machine elements depending on actual operating conditions from the torque and the operating speed. <P>COPYRIGHT: (C)2004,JPO |
