Embodiment 1

[0068] Example 1. A design method for lightweight double-layer structure of palm mattress, the design method is as follows:

[0069] Design the brown mattress with a length of 2000mm, a width of 1800mm and a thickness of 120mm. The double palm mattress is divided into an upper mattress layer and a lower mattress layer, and the thickness of the lower mattress layer is designed to be 4 times the thickness of the upper mattress layer, that is, the thickness of the upper mattress layer is 24mm, and the thickness of the upper mattress layer is 96mm.

[0070] Firstly, use ANSYS software to establish the mountain palm material model of the mattress. Using the method of finite element solution, the brown mattress model corresponding to the length, width and thickness is established with the brown material model. Then apply human body load on the brown mattress model, the area of ​​the load is 1700mm×800mm, and the weight is 80kg; the stress deformation test is performed on the mattr...

Embodiment 2

[0073] Example 2. A design method for a lightweight double-layer structure of a brown mattress, the model building method and the stress deformation test method of the present embodiment are the same as the embodiment 1. In this embodiment, the brown mattress with a length of 1800mm, a width of 1600mm and a thickness of 120mm is designed as a lightweight double mattress layer structure. The thickness of the lower mattress layer is designed to be 3.5 times the thickness of the upper mattress layer, the thickness of the upper mattress layer is 26.7mm, the thickness of the lower mattress layer is 93.3mm, and the lower winding value of the upper mattress layer and the lower mattress layer Select the plane where the stress center of the mattress layer is located, and select a deflection value within 10mm from the stress center of the mattress layer as the downdeflection value. Use the deflection values ​​of the upper mattress layer and the lower mattress layer to set the density o...

Embodiment 3

[0075] Example 3. A design method for a lightweight double-layer structure of a brown mattress, the model building method and the stress deformation test method of the present embodiment are the same as the embodiment 1. In this embodiment, the brown mattress with a length of 1800mm, a width of 1600mm and a thickness of 150mm is designed as a lightweight double mattress layer structure. The thickness of the lower mattress layer is designed to be 3 times the thickness of the upper mattress layer, the thickness of the upper mattress layer is 37.5mm, the thickness of the lower mattress layer is 112.5mm, and the lower winding value of the upper mattress layer and the lower mattress layer Select the plane where the stress center of the mattress layer is located, and select a deflection value within 6mm from the stress center of the mattress layer as the downdeflection value. Use the deflection values ​​of the upper mattress layer and the lower mattress layer to set the density of ...

Abstract

The invention discloses a design method of a lightweight double-layer structure of a palm mattress. The method comprises the following steps: designing a palm mattress into an upper mattress layer anda lower mattress layer; the method comprises the following steps: establishing a palm mattress model, applying a human body load to the palm mattress model, carrying out stress deformation analysis,measuring the deflection values of an upper mattress layer and a lower mattress layer in the palm mattress model, and setting the density of each mattress layer according to the deflection values of the upper mattress layer and the lower mattress layer to obtain the lightweight double-layer structure of the palm mattress. By adopting the method disclosed by the invention, the lightweight structural design of the palm material mattress can be guided, the palm material mattress is designed into an upper mattress layer structure and a lower mattress layer structure, and the densities of the uppermattress layer and the lower mattress layer are respectively designed, so that the light weight of the mattress is realized. Through the design of the invention, the total density of the palm fiber mattress can be reduced, the use amount of mattress materials is saved, the production cost is reduced, and the product quality can be ensured.

Description

technical field [0001] The invention relates to the field of brown mattress design, in particular to a design method for a lightweight double-layer structure of a brown mattress. Background technique [0002] Palm mattress materials include mountain palm, coconut shell, etc., all of which are plant fiber elastic materials. CN90100464.2 discloses a production method of plant fiber elastic material that can be used to produce brown mattresses. After crimping, brown silk (palm fiber) is blown into a three-dimensional distribution with airflow and then sprayed with glue, so that the nodes between the brown silk are bonded The brown silk elastic sheet is obtained, and then the brown silk elastic sheet is stacked to obtain a layered brown silk elastic material. The brown silk elastic material is bonded with latex, pressed into sheets, hot-pressed and vulcanized. Brown mattresses can be made. [0003] Judging from the current domestic and foreign research on mattresses made of pl...
