摘要： A multi-axis force platform for determining forces and moments exerted on the platform along x, y and z axes includes at least one multi-axis spring. The multi-axis spring includes a block of rigid material through which a pattern of slots pass through to form a series of deflectable beams separated from each other by the slots. The deflectable beams surround an interior region of the spring and elastically couple the interior region of the spring to an outer region of the spring such that the interior region can deflect relative to the outer region along x, y and z axes when subjected to a load. One or more magnetic sensors are positioned within the interior region of the spring for sensing loads exerted on the spring.

摘要： In a force measuring platform, a top plate 12 is supported on tubular load cells 16. The load cells have strain gages to measure the strain due to the horizontal shear forces. The "shear" strain gages also measure moments about the Z axis when properly placed in a bridge circuit. Strain gages mounted to measure vertical strain indicate vertical forces and moments about horizontal axes.

摘要： An apparatus and method for a multi-axis wheel transducer are disclosed. The apparatus of the invention comprises a wheel transducer for measuring the loads and moments acting on a vehicle wheel. Tubular load cells positioned in a radial fashion around the perimeter of the transducer hub join the rim and hub. Loads and moments acting on the rim of the wheel are transferred through the spoke-like load cells to the hub of the wheel. Sensors strategically positioned around the circumference of the tubular load cell monitor the intensity of the loads and moments. To detect angular position of the wheel, a light source generates a cone of polarized light to flood the wheel of the vehicle and detector-polarizing filter pairs detect an angle of the polarization relative to the wheel to determine its angular position. The transducer hub computer processes the sensor data and transfers the information via infrared signal to a computer located in the fender of the vehicle.

摘要： A force measuring apparatus includes a platform construction on which forces may be exerted, as for example, by an individual stepping upon a top plate of the platform construction. Apparatus of this nature is commonly referred to in the art as a "Biomechanics Platform", and may include a bottom plate, a top plate deformable by forces exerted thereon and a plurality of load cell members arranged to yieldably support the top plate in spaced relation to the bottom plate. The load cells are constructed with strain ring means having strain gage elements suitably supported thereon, and the cells further include composite anchoring means for connecting the top plate with strain rings of respective load cells in a unique manner. Each of the composite anchoring means includes a compliant or elastic member which is arranged to transmit, at any given time, an entire load exerted between the top plate and its respective load cell. Also included in each composite anchoring means are retaining elements arranged to engage with a respective elastic member as well as adjacent top plate and strain ring portions. The elastic member is further characterized by a compliance with respect to rotation and lateral translation of the top plate greater than the compliance of the entire load cell structure, thereby to eliminate to a very large extent transmission of erroneous force signals resulting from deformation of the top plate.

摘要： A joint motion simulator to simulate biomechanical motion includes a mount to which a prosthetic device is mounted, actuators coupled to the mount to drive the mount, and a programmable controller to drive the actuators to translate the mount and to rotate the mount with a center of rotation controllable independent of translation. The simulator can include a linear actuator to translate the mount in a linear direction substantially parallel to the axis of rotation. The linear actuator can include a piston within a sleeve, the piston being coupled to the mount and being hydraulically driven to translate the mount, and the actuators can be coupled to the sleeve. The controller may be programmed to vary the center of rotation with linear translation and rotation of the mount. Sensors may be included that measure displacement of the actuators. The controller may drive the actuators based on the measured displacement.

Next, applying p known loads on each of the n×m grid points of the top surface along a Z-axis being perpendicular to the X and Y axes and along the X and Y axes. Next, taking multipoint measurements at each grid point and for each applied known load along the X, Y and Z axes and generating six measured output signals, exact position coordinates and applied known load magnitude for each grid point. Next, assembling an array of n×m×p of six equations with six unknown for each grid point and applied known load and then solving the assembled equations and deriving a position and load specific calibration matrix for each grid point.
