METHOD FOR CALIBRATING STRAIN TRANSDUCERS |
| 摘要 |
A method for calibrating strain transducers mounted to a power shovel may include the steps of: Calculating at least one member joint load for a known loading condition when at least one member of the power shovel is in a statically determinate configuration; determining a calculated shear force and a calculated normal force in the member of the power shovel based on the calculated member joint load; measuring a strain in the member; determining a measured shear force and a measured normal force for the member based on the measured strain; and determining a calibration constant from the calculated shear and normal forces and the measured shear and normal forces. |

1. A method of calibrating strain transducers mounted to a power shovel, comprising:
calculating at least one member joint load for a known loading condition when at least one member of the power shovel is in a statically determinate configuration; determining a calculated shear force and a calculated normal force in said at least one member of the power shovel based on the calculated member joint load; measuring a strain in said at least one member; determining a measured shear force and a measured normal force for said at least one member based on the measured strain; and determining a calibration constant from the calculated shear and normal forces and the measured shear and normal forces. |
