Abstract:
A force-moment measuring apparatus, comprising:a mechanical parallel type six-axes force-moment measuring structure including, a first support plate providing a static reference frame; a plurality of vertical members extending from the first support plate and seperated from one by another a predetermined distance; a plurality of horizontal members, each one said plurality of horizontal members being transversely supported with respect to a corresponding one of said vertical members; a second support plate being parallel and spaced apart from said first support plate by a predetermined distance, said second support plate being adapted to receive an arbitrary load; three connecting arms, each one of said arms connecting said second support plate with a corresponding one of said horizontal members, said arm extend radially from said central axis and are angularly spaced with respect to one another at predetermined angles; and a spider commonly connecting each of said plurality of arms at a central axis and for support the second support plate; a plurality of sensors installed at predetermined positions on the mechanical structure for measuring tensile and compressive forces along respective axes, said plurality of sensors outputting a sensor signal; a first signal processor electrically connected to said plurality of sensor for receiving and amplifying the sensor signal, said first signal processor outputting an amplified signal; a second signal processor electrically connected to said first signal processor for receiving and converting the amplified signal, said second signal processor outputting a converted signal; a signal analyzer electrically connected to said second signal processor for receiving the converted signal and calculating forces and moments applied to the mechanical structure; and an output device electrically connected to said signal analyzer for indicating the forces and moments calculated by said analyzer.
