Description
Technical field
The utility model relates to a kind of tester of studying friction force, belongs to education experiment apparatus technical field.
Background technology
In traditional friction force education experiment, need hand to take dynamometer, haul friction block and make horizontal linear uniform motion, read the registration of dynamometer simultaneously, change the size (adding counterweight) of pressure, the degree of roughness (shield of change surface of contact then respectively, towel), the size (slide block is sidelong) that changes contact area repeatedly tests, data and experiment condition that dynamometer is recorded compare, thereby draw experiment conclusion.This experimental technique is too high to operator's gimmick requirement, and be difficult to accomplish to pull slide block and do linear uniform motion and keep the direction of pull level, thus complicated operation, and success ratio is low.
Though the friction force experimental provision that adopts force transducer to substitute dynamometer is also arranged, same because operation technique does not fundamentally solve the complicated and bigger problem of experimental result error of experimental implementation.
Summary of the invention
The utility model is at the deficiency that existing friction force experimental technique exists, and a kind of simple to operate, friction force tester that experiment effect is good is provided.
Friction force tester of the present utility model adopts following technical solution:
This friction force tester comprises force transducer, friction seat, rail bed and motor, motor is fixed on the bottom of rail bed, wired hub is installed on the motor shaft, the friction seat lies on the rail bed and by cotton rope and is connected with the line hub, friction seat upper surface is provided with removable frictional layer, be placed with friction block on the frictional layer, force transducer is fixed on the rail bed and by stay cord and is connected with friction block.
The surface of rail bed is provided with scale, probes into experiment in order to extendability and uses.
The bottom surface of rail bed is provided with battery case, can be the motor power supply by the battery in the battery case.
Force transducer adopts the disclosed surface structure of Chinese patent CN3406708.Force transducer also can adopt other forms, as weight beam etc.
When carrying out the friction force experiment, force transducer is connected with the external data collector, starter motor, motor at the uniform velocity rotates and drives rubbing table does horizontal linear uniform motion, friction is arranged between friction block and the rubbing table and do relative motion, force transducer is measured the friction force between the frictional layer on friction block and the rubbing table automatically, by data acquisition unit the experimental data that collects is shown and preservation automatically by computer software then, can utilize the data processing function of this software that data are analyzed simultaneously.Change the material and the quality of friction block, change different rubbing table or frictional layer, change the size of contact area, utilize with quadrat method and obtain many group experimental datas, analyzed relatively, can be drawn the size of the force of sliding friction demonstration relevant with pressure, the degree of roughness of surface of contact.
This tester keeps friction block motionless, utilize uniform rotation motor drawing friction platform to do linear uniform motion accurately, show intuitively and preserve this data by the accurate experiments of measuring data automatically of force transducer and by computer software, artificial reading and the problem of calculating inaccurate and complicated operation have been avoided, sensitivity is higher, and is simple to operate, and experiment effect is good, simultaneously simple and reasonable, cost is low.
