Abstract
A three-bar first order type tension measuring method is used for leading a rope to vertically penetrate a measuring device; firstly the tensed rope is arranged at the middle line of the measuring device by the special structure design of the measuring device in a three-fixed supporting bar form, and the rope partially forms a small angle by the different positions of the axes of the three fixed supporting bars; a component force formed at a special direction is detected by setting a group of tension sensors on a certain measuring bar; then a tension amount value is obtained by signal processing and first order model calculation.
Description
Technical field
Tension measurement physical construction computing method
Background technology
Traditional rope pull measuring method generally adopts photostat to measure, or mechanical threshold values judges that performance is relatively poor relatively on precision, and price with improve and significantly increase with precision, be unfavorable for the utilization and the popularization of rope pull measurement.
Summary of the invention
The present invention is directed to the deficiency of existing rope pull measuring method technology, designed a kind of integrated sensor technology, Machine Design, computing method, the measuring method of tensile force of electronic technology has realized that low-cost and high-performance measures the function of rope pull.
Description of drawings
This figure is the structural drawing of this method.
Embodiment
Three bar single order type tension measurement method is to make rope vertically pass measurement mechanism, and at first the measurement mechanism special construction design by three fixed thick stick forms makes the rope of tensioning be positioned at the device midline; And the diverse location by three fixed thick stick axis, make the local low-angle that forms of rope; By on a certain measurement thick stick, setting one group of pulling force sensor, measure the component that specific direction forms; Calculate by signal Processing and first order modeling again, obtain the tension force value.
This measurement mechanism special construction design outside is fixed left-right symmetric framework, can form vertical axis of symmetry; Framework inside is provided with three and measures thick sticks, wherein up and down two measure the same side that thick stick is fixed in framework, measure thick stick and be fixed in the framework opposite side for middle one; Three on-fixed ends of measuring thick stick all are equiped with pulley; Rope passes around the pulley of upper, middle and lower three thick sticks successively; Measure the thick stick extension position up and down and just make critical contact that rope walks around pulley up and down respectively on the vertical axis of symmetry of framework, formed error can be ignored, and wherein critical contact finger is crossed rope and the critical point that contacts of pulley.
Contact and middle thick stick stiff end that middle thick stick extension position makes rope walk around middle thick stick pulley lay respectively at the vertical axis of symmetry of framework both sides.
Choose and measure one of thick stick, on thick stick, set up one group of pulling force sensor, measure the stressed vector value of selected thick stick or measure the stressed vector value of selecting tight certain direction of thick stick.
By electronic information technology,, and calculate sensor information filtering; According to metering system, set up first order modeling, by the component of measuring, and the compensation computing method by first order modeling, calculate rope tension.
