Embodiment 1

[0063] Example 1. A method for evaluating the elasticity of a mattress, which is carried out according to the following steps:

[0064] a. Statically press the mattress material sample;

[0065] b. Record the stress relaxation changes during the static pressure process, and obtain the trend equation:

[0066] ε=at+b;

[0067] Among them, the parameter t represents the static pressure time, ε represents the stress relaxation, a represents the slope, and b represents the stress relaxation at time 0;

[0068] d. For more than one static pressure period Δt i Stress relaxation change within Δε i Perform the weighted summation and average to obtain the weighted average δ, namely:

[0069]

[0070] Among them, i represents the i-th time period Δt i , n means that there are n Δt i time point, f i Represents the stress relaxation change Δε i the weight of;

[0071] e. Determine the elasticity of the mattress according to the obtained δ value, and the δ value and the elastici...

Abstract

The invention discloses a mattress elasticity evaluation method. The method comprises the following steps that: a, static compression is carried out on a mattress material sample; b, stress relaxationchange in the static compression process are recorded, so that a trend equation that epsilon=at+b is obtained, wherein the parameter t represents static compression time, epsilon represents stress relaxation, a represents slope, and b represents stress relaxation at the moment of 0; d, weighted summation averaging is performed on stress relaxation change Delta epsilon i in more than one static compression time period Delta ti, so that a weighted average value delta is obtained, wherein i represents the ith time period Delta ti, n represents n Delta ti time points, and fi represents the weightof the stress relaxation change Delta epsilon i; and e, the elasticity of a mattress is judged according to an obtained Delta value, wherein the Delta value and the elasticity of the mattress are ina monotonically decreasing relationship. According to the mattress elasticity evaluation method of the invention, a mattress elasticity quantification method is established. Compared with a traditional elasticity evaluation method, the mattress elasticity evaluation method is more accurate in evaluation.

Description

technical field [0001] The invention relates to the field of mattress testing, in particular to a method for evaluating the elasticity of mattresses. Background technique [0002] With the improvement of people's living standards, people also pay more and more attention to the quality of sleep. Most mattresses on the market currently have a uniform structure with a single hardness and elasticity, which can no longer meet people's high requirements for sleep quality. In response to market demand, customized mattresses have emerged, which mainly collect information such as users' sleeping habits, physical data, and sensory feelings to tailor-made mattresses for users to meet sleep needs. With the rise of custom mattresses, there has been a lot of scientific research around the performance of mattresses in all aspects. The elasticity index of the mattress has an important influence on the stress of the human body. The use of good elastic materials to make a mattress has a very...
