摘要： The purpose of the present invention is to provide a control device for a dynamometer system, with which, by a simple method, an unloaded state can be reproduced highly accurately when a test piece is started. A dynamo control device 6 is provided with: an integral control input computation unit 611 for computing the integral value of axle torque deviation, and multiplying the sum thereof and a correction value by an integral gain to compute an integral control input; a correction value computation unit 612 for multiplying an inertia compensation quantity Jcmp by the dynamo rotation frequency to compute a correction value; a non-integral control input computation unit 613 for designating, as a non-integral control input, the output of a prescribed transmission function Ge0(s) having axle torque deviation as input; and a totaling unit 614 for totaling the integral control input and the non-integral control input in order to generate a torque current command signal to the dynamometer. The transmission function Ge0(s) of the non-integral control input computation unit 613 is derived by separating the integrator from a transmission function Ge(s) having an axle torque control function, in such a way as to satisfy the relational equation (Ge(s)=Ki/s+Ge0(s)).

摘要： The structure for detecting tooth-skipping of the speed reducer of the rotary driver is reduced in weight and size. In the rotary driver the occurrence of tooth-skipping is detected based on the difference in outputs from the encoders located at the input side (the side of the motor) and at the output side (the side of the load), which is opposite the input side in relation to the speed reducer. The rotary driver comprises a motor, a speed reducer located between the motor and a load to reduce the rotary speed of a rotary shaft at the side of the motor, to thereby transmit the reduced rotary speed to a rotary shaft at the side of the load, a first encoder for detecting a rotation of the rotary shaft at the side of the motor, a second encoder for detecting a rotation of the rotary shaft at the side of the load, a section for detecting any difference between a first detected value that is obtained by dividing an output of the first encoder by a rate for reducing the speed by the speed reducer and a second detected value that is obtained from an output of the second encoder, and a section for detecting tooth-skipping that detects tooth-skipping of the speed reducer based on the difference.

摘要： A device (1) for determining the torque applied to a crankset shaft (10) moveable in rotation about an axis of rotation, includes a supporting element (50). The crankset shaft (10) has two separate parts that are moveable in rotation, the supporting element being designed to keep the two parts substantially coaxial with the axis of rotation. Furthermore, the two parts have respective contact elements designed to transform the rotational movement of one of the two parts into a simultaneously translational and rotational movement of the other of the two parts, as well as stop element designed to cooperate with the supporting element. The device also has at least one sensing element (80) designed to provide a signal representing a mechanical stress applied to the at least one sensing element, and a processing module configured to determine the torque as a function of the signal.

摘要： A magnetostrictive measurement system having one or more encoded polarized magnetic regions disposed circumferentially about a shaft, wherein adjacent magnetic regions along a section of the shaft have opposing polarities. In one embodiment the shaft is hollow and the encodings are interiorly disposed while in another embodiment the encodings are on the exterior surface of the shaft. There are one or more sensors, such as contact sensors, disposed about the shaft wherein the sensors enable measurements of at least one of bending moments or torque sensing. The sensors can also include non-contact sensors measuring the magnetic flux densities caused by the alternating magnetic fields from the rotating shaft. A processing section is used to process the sensor measurements, wherein the sensor measurements are used to compute at least one of shaft power, torque, speed, and bending moments.
