Abstract:
The purpose of the present invention is to provide a test piece characteristic estimation method capable of quickly measuring the moment of inertia of a test piece while taking loss resulting from rotational friction of the test piece into consideration. This test piece characteristic estimation method is provided with a step (S 1 ) for measuring a first transfer function G 1  from a torque current command for a dynamometer to output from a shaft torque sensor by vibrationally operating the dynamometer, a step (S 2 ) for measuring a second transfer function G 2  from the torque current command to the output of a dynamo rotation speed sensor by vibrationally operating the dynamometer, and steps (S 3  and S 4 ) for calculating the value of a ratio obtained by dividing the second transfer function G 2  by the first transfer function G 1  at a prescribed measurement frequency ω k  and using the ratio value to calculate a moment of inertia Jeg and a rotational friction Ceg.

Claim (Index 11):
The test piece characteristic estimation method according to  claim 8  wherein, in the step of estimating, n-number (\u201cn\u201d is an integer of 2 or more) of different measurement frequencies are defined as \u03c9 k _ j  (\u201cj\u201d is an integer from 1 to n), a real part and an imaginary part of the ratio at the respective measurement frequencies \u03c9 k _ j  are defined as a k _ j  and b k _ j , and using the values thereof, a value of the moment of inertia Jeg of the test piece is calculated according to the estimation formula below. Jeg = - 1 n \ue89e \u2211 j = 1 n \ue89e b k \ue89e \ue89e _ \ue89e \ue89e j ( a k \ue89e \ue89e _ \ue89e \ue89e j 2 + b k \ue89e \ue89e _ \ue89e \ue89e j 2 ) \ue89e \u03c9 k \ue89e \ue89e _ \ue89e \ue89e j ( 8 )
