Embodiment 1

[0068] Example 1. A design method for the lightweight structure of a 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 brown mattress is layered, and the brown mattress is designed as a double mattress layer structure with an upper layer 30mm thick and a lower layer 90mm thick.

[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×700mm, and the weight is 80kg; the stress deformation test is performed on the mattress model after the human body load is applied, and the down deflection value of each mattress layer is obtained, and the down winding The selection point of the val...

Embodiment 2

[0073] Example 2. A design method for a lightweight 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. The underwinding value of each mattress layer is selected on the plane where the stress center of the mattress layer is located, and a deflection value within 15mm from the stress center of the mattress layer is selected as the downdeflection value. When using the deflection value of each mattress layer to set the layer density, the value of k is 80. According to the deflection value of each mattress layer, the layer density is set, and the design density of each mattress layer is calculated. In this embodiment, the brown mattress with a length of 1800mm, a width of 1600mm and a thickness of 120mm is designed as a structure of three layers of mattress layers. Among them, the thickness of the upper mattress layer is 20mm, and the density is 121kg / m 3 ;The thickness of th...

Embodiment 3

[0074] Example 3. A design method for a lightweight 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. The underwinding value of each mattress layer is selected on the plane where the stress center of the mattress layer is located, and a deflection value within 10mm from the stress center of the mattress layer is selected as the downdeflection value. When using the deflection value of each mattress layer to set the layer density, the value of k is 85. According to the deflection value of each mattress layer, the layer density is set, and the design density of each mattress layer is calculated. In this embodiment, the brown mattress with a length of 2000mm, a width of 1800mm and a thickness of 150mm is designed as a structure of three layers of mattress layers. Among them, the thickness of the upper mattress layer is 30mm, and the density is 124kg / m 3 ; The thickness of t...

Abstract

The invention discloses a design method of a lightweight structure of a palm mattress. The method comprises the following steps: layering a palm mattress to obtain mattress layers, establishing a palmmattress model, applying a human body load to the palm mattress model, carrying out stress deformation analysis, measuring the deflection value of each corresponding mattress layer in the palm mattress model, and setting the density of each mattress layer according to the deflection value change of each mattress layer to obtain the light-weight 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 a layered structure, and the density of the mattress is designed, so that the light weight of the mattress is realized. Through the design, the total density of the palm fiber mattress can be reduced, the use amount of mattress materials is reduced, the production cost is reduced, and the product quality can be guaranteed.

Description

technical field [0001] The invention relates to the field of palm mattress design, in particular to a design method for the lightweight structure of the palm 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 plant fiber e...
