Description
Technical field
The present invention relates to Physical Experiment parameter measurement fields, are especially utilizing air heat engine research torque meter work done
When to the precise measurement of moment of friction.
Background technique
Currently, measuring torque using pointer torque meter in the experiment of air heat engine.When measuring torque,
By adjusting screw, thus it is possible to vary the frictional force between torque meter and the flywheel shaft of air heat engine experiment instrument checks power
The pointer of square meter can read moment of friction in the reading of dial.But it is deposited using pointer torque meter measurement moment of friction
In very big error: (1) during flywheel shaft rotates, pointer torque amplitude of fluctuation is excessive, leads to error in reading pole
Greatly, it is intervened if applying external force, stablizes pointer registration, the accuracy of registration will be impacted, same meeting
Introduce biggish error.(2) dial of pointer torque meter is easy to fall off, can generate friction with flywheel after falling off, simultaneously because
Scale deviates, and carrys out biggish error to sensing tape, in view of the above-mentioned problems, it has been proposed that corrective measure: such as utility model patent " one
Kind air heat engine torgue measurement display device ", the patent No.: 201620055647.9, but still not can be carried out accurate reading.
Summary of the invention
It is big that there are errors in reading to overcome the problems, such as pointer torque meter, and the present invention proposes a kind of not utilizing pointer torque
The method for counting to measure moment of friction size can be well that is, using the method for pressure sensor measurement air heat engine torque
Solve this problem.
The present invention realize goal of the invention the technical solution adopted is that: utilize pressure sensor measurement air heat engine torque side
Method, it is characterized in that: being that the small cylinder formula pressure sensor (model are as follows: EVT-14T) annular, material is steel is tight by a shape
It is tightly placed in the flywheel shaft of air heat engine experiment instrument, and fixed, the shaping drum and air heat engine experiment instrument of load cell
Flywheel shaft formed an entirety, torque meter is mounted on test surface-shaping drum of load cell, pressure sensor
(model are as follows: EVT-14T) can directly measure the pressure F that torque meter applies sensor, and directly show the numerical value of pressure F
Show on the display screen of pressure sensor (model are as follows: EVT-14T), after obtaining institute measuring pressure F, to torque meter, load cell
Shaping drum and air heat engine experiment instrument flywheel shaft carry out force analysis: by the flywheel shaft of air heat engine experiment instrument
An entirety is regarded as with the shaping drum of pressure sensor, then the torque that torque meter generates air heat engine is,
Wherein:For the square meter radius of gyration (r=5mm),For the shaping drum of pressure sensor and the friction factor (steel-steel of torque meter
Dynamic friction factor), therefore after measuring F, torque can be accurately obtained.
Actual gain of the invention is: measurement accuracy is high, and measuring speed is fast, and change is at low cost, convenient for promoting.
