This biggest stiction testing arrangement, through setting up the horizontal plate, the reduction slope has strengthened experimental accuracy nature to the influence of test result, through the signal that force sensor records, with showing on the display screen, has reduced the error that artifical reading brought between the pulling force that records, simple structure, measuring result is accurate, has better market prospect.
Description
Technical field
This utility model belongs to experimental provision technical field, is specifically related to a kind of maximum static friction force test device.
Background technology
The frictional force occurred in static friction is referred to as stiction.Static friction force is different from general restriction counter-force, it
Unrestrictedly do not increase with the increase of external force.When the size of external force reaches certain numerical value, object is in and will slide, but
Do not start again the critical state slided.
The experiment test device of prior art, uses scale reading, and the size of the power read is inaccurate, brings to experiment
Error, and be object is placed directly in laboratory table measurement, the levelness of laboratory table is inadequate, to the measurement of stiction also
Bring error.

In ergometer enclosure.
Preferably, described coupling hook is connected through adpting flange and spring are fixing.
Preferably, described coupling hook is fixing with experiment thing block contact surface center is connected.
Technique effect of the present utility model and advantage: this maximum static friction force test device, by arranging horizontal plate, reduce
The gradient impact on test result, increases the accuracy of test, by signal measured by pulling force sensor, on a display screen will
Show between measured pulling force, decrease the error that artificial reading is brought, this assay device, simple in construction, measure
Result is accurate, has preferable market prospect.
Accompanying drawing explanation
