Problems solved by technology

In fact, the depression of the mattress will cause the feeling of instability to the human body, but it is not obvious because the depression speed is slow, but this kind of depression is not good for the relaxation of human muscles and the human spine

Embodiment 1

[0067] Example 1. A method for judging a mattress support stability index, the steps are as follows:

[0068] Step 1: Place a mattress sample block with a size of 300*300*60 on the platform of the TM2101 universal material tensile testing machine; the diameter of the circular pressure plate of the universal material tensile testing machine is 200mm;

[0069] Step 2: Use the program of the universal material tensile testing machine to set the pressing parameters. The setting content is: the speed is set to 5mm / min, the pressure is ≦21kg for testing, and the displacement and time change curve of the mattress sample is measured;

[0070] Step 3: Save the test results, and record the values ​​of points on the curve of displacement and time change. The first point is the value of the y-axis when the pressure is 21kgn and is recorded as Y1, and the second point is the value of the y-axis when the force is applied. Denote it as Y2;

[0071] Step 4: Use the formula §=Y2-Y1 to calcul...

Embodiment 2

[0073] Example 2. A method for judging a mattress support stability index, the steps are as follows:

[0074] Step 1: Place a mattress sample block with a size of 300*300*80 on the platform of the TM2101 universal material tensile testing machine; the diameter of the circular pressure plate of the universal material tensile testing machine is 200mm;

[0075] Step 2: Use the program of the universal material tensile testing machine to set the pressing parameters. The setting content is: the speed is set to 10mm / min, the pressure is ≦5kg for testing, and the displacement and time change curve of the mattress sample is measured;

[0076] Step 3: Save the test results, and record the values ​​of points on the curve of displacement and time change. The first point takes the value of the y-axis when the pressure is 5kgn and records it as Y1, and the second point takes the value of the y-axis when the force is applied. Denote it as Y2;

Embodiment 3

[0079] Example 3. A method for judging a mattress support stability index, the steps are as follows:

[0080] Step 1: Place a mattress sample block with a size of 300*400*120 on the platform of the TM2101 universal material tensile testing machine; the diameter of the circular pressure plate of the universal material tensile testing machine is 220mm;

[0081] Step 2: Use the program of the universal material tensile testing machine to set the pressing parameters. The setting content is: the speed is set to 20mm / min, the pressure is ≦30kg for testing, and the displacement and time change curve of the mattress sample block is measured;

[0082] Step 3: Save the test results, and record the values ​​of points on the curve of displacement and time change. The first point is the value of the y-axis when the pressure is 30kgn, which is recorded as Y1, and the second point is the value of the y-axis when the force is applied. Denote it as Y2;

Abstract

The invention discloses a method for judging a mattress supporting stability index. According to the method, the supporting stability grade of the mattress is judged by using the creep value Xi of themattress, and the judgment method is as follows: the supporting stability of the mattress is very good when the section is less than or equal to 2 mm and the grade is A; the supporting stability of the mattress is good when the section is more than 2mm and less than or equal to 4mm, and the grade is B; the supporting stability of the mattress is common when the section is greater than 4mm and less than or equal to 6mm, and the grade is C; the supporting stability of the mattress is relatively poor when the section is more than 6mm and less than or equal to 8mm, and the grade is D; and the supporting stability of the mattress is poor when the section is more than 8 mm, and the grade is E. According to the method, the supporting stability of the mattress is judged according to the creep value Xi of the mattress, the judgment method is simple, the mattress is quantitatively judged from the using process and the functional direction of the mattress, the supporting stability of the mattress can be visually reflected, and when the index of the supporting stability of the mattress is poorer, it is indicated that the human body lies on the mattress for a longer time, and the more seriousthe sinking is; and the test is accurate.

Description

technical field [0001] The invention relates to the field of evaluation of mattress support stability, in particular to a method for evaluating the stability index of mattress support. Background technique [0002] Indexes such as mattress elasticity and hardness are mainly instantaneous quantities, but it is a long process for people to lie on the mattress. During this process, does the mattress have any impact on the human body? What is the effect? There are few studies on this aspect at this stage, but it can be found in life that when a constant force is continuously applied to a viscoelastic object, the object will slowly deform over time. For example, if a person sits on the sofa for a long time, he will find that the sofa under the buttocks will be significantly deeper than when he first sat on it. Similarly, the human body lying on the mattress will also have such a situation, but the human body lies flat on the bed, due to the effect of force dispersion, the depre...
