摘要： The method for measuring torque described is based upon the fact that angular velocity omega and angular acceleration Alpha are independent dynamical variables at any given time. Thus, for any given omega , a simultaneous determination of Alpha and omega can be utilized for a determination of power. The method of measurement requires a negligible perturbation of the rotating system. It is easily susceptible to modification over a wide range of variations.

摘要： A performance analyzer for use in conjunction with prime movers and vehicles, wherein circuitry electrically connected to the vehicle produces a first electrical signal having a frequency proportional to the vehicle velocity, as for example, measurement of the rotational velocity of a member associated with the prime mover. Other circuitry is provided for producing an electrical signal proportional to the rate of change of the first signal. The two electrical signals are multiplied together electrically and connected to a measuring device to thereby ascertain the available power of the vehicle. The circuitry includes apparatus by which one of the signals can be used to measure the velocity of the vehicle or the rpm of the prime mover, while also enabling the acceleration of the prime mover to be measured by bypassing the multiplier. Hence the analyzer of the present invention measures the velocity, acceleration, and available power of the vehicle.
