Description
Technical field
The utility model is related to observation and control technology field, specifically a kind of relaxing of spring measure and control device.
Background technology
Load loss percentage is represented after relaxing of spring rate ε is tested with spring：
F in formula --- the spring load determined before experiment；
Fi --- the spring load determined after experiment.
Stress relaxation is substantially that material produces micro-plastic deformation under stress, and is gradually accumulated, and is being kept
On the premise of strain or shift invariant, the phenomenon that stress reduces with time duration is shown as.Stress relaxation is a kind of suitable
The phenomenon of generally existing, is not only present in the flexible member or component manufactured by metal material, exists in by nonmetallic system
It is basic part, precision instrument and the instrument such as various mechanical springs (such as valve spring and buffer spring), bolt in the component made
One of dominant failure mode of elastic element.These phenomenons are much in daily life, and severe patient can cause huge
Economic loss.
Measure relaxing of spring device typically use more original experimental provision, have not yet to see it is a kind of can be to spring
The measure and control device of automatic detection is carried out under different temperatures, different states of tension.
Utility model content
In order to solve the above technical problems, the purpose of this utility model is to provide one kind can automatically carry out temperature control and pulling force
The spring measure and control device of loading, concrete technical scheme is as follows：
A kind of spring hot wire-CVD experimental rig, including high-temperature cabinet, the fixed zone of heating of the interior setting of the high-temperature cabinet and activity add
Thermosphere, described fixed zone of heating and movable zone of heating opposition is set, and heating unit is set in fixed zone of heating and movable zone of heating
Part；Hook is set on fixed zone of heating and movable zone of heating, and spring is hung between two hooks that opposition is set；Fixed zone of heating
