In, the tactile sensor that is fixed in heat pipe wall experiences force value, obtain when tubing is socketed in heat pipe wall with heat pipe wall it
Between the contact that generates, i.e. radial pressure Fr；Pressure sensor experiences force value and obtains taking out force, with reference to the mobile position of moving beam
Shifting and the temperature value of heat pipe obtain the withdrawing force-displacement curve (Fx curves) of tubing under condition of different temperatures, by the curve
Tubing axial direction unit area frictional force Δ f can be obtaineda(since entire inflection withdrawing process remains a constant speed movement, therefore Δ fa=
F the maximum taking out force F) and under normal temperature conditionnmaxWith maximum taking out force F under the high temperature conditionshmax, managed by calculating
The axial friction f that shape fabric generates when being socketed in heat pipe wallaAnd smoothness S of the tubing during inflection withdrawing with
Smooth attenuation rate δS。
Smoothness is to characterize tubing to be socketed on the smooth degree in heat pipe wall occurred when inflection withdrawing acts on, and S ∈
(0,1), the value show that more greatly the effect of tubing and heat pipe wall is smaller, i.e., smoothness is better, but when the value is close to 1, then
It may be that lubricant is coated in heat pipe wall or coating treatment has been carried out to tubing surface in advance, to fabric and can may deposit
Application places cause the local pollution of the environment, be unfavorable for the accuracy of practical measurement index.
If the smooth attenuation rate δ of 0 ＜S＜ 1 then shows that high temperature causes tubing more soft or even few fibers material is soft
Change, the contact with heat pipe wall is even closer, and lock knot power becomes larger, and is unfavorable for the progress of inflection withdrawing effect；If δS＜ 0, then show
High temperature action makes the Fiber Materials inside tubing that chemical change occur, and regenerates chemical bond, fabric tissue point more steps up
Close, fabric surface filoplume reduces even surface and has been carbonized, and the smoothness under hot conditions is caused to increase.
Radial pressure FrIt represents the degree of gripping keying action between tubing and heat pipe wall, that is, generate normal pressure and bears
The degree of pressure (extruding force).Tubing from heat pipe outer wall is socketed on to during pulling heat pipe inner wall by inflection withdrawing,
FrNegative value is first changed from positive to, is become from using normal pressure to be leading using extruding force to be leading.Can if two power are excessive during being somebody's turn to do
The withdrawing smoothness of tubing is impacted, tubing is resulted even in and is broken by withdrawing, cause test failure.
Axial friction faIt represents tubing smooth degree on the heat pipe walls, especially characterizes tubing from being socketed on
Heat pipe outer wall is to the complexity that heat pipe inner wall during pulling heat pipe inner wall by inflection withdrawing, is slipped into from heat pipe outer wall.fa
It is bigger, show that heat pipe wall is bigger to the friction level of tubing, then tubing is more difficult to slip into heat pipe inner wall from heat pipe outer wall,
Fatigue rupture of the tubing in heat pipe head end corner is increased, the withdrawing for easily causing tubing is broken.
