Embodiment Construction

[0026] The present invention will be further described below in conjunction with the accompanying drawings and specific embodiments.

[0027] refer to figure 1 , shows the flowchart of the component distribution method of the car seat frame of the present invention. The invention provides a component distribution method of a car seat frame, selects a design area in the original model of the car seat frame, establishes a reasonable finite element model for the selected design area, and adopts the variable density method to analyze the finite element The topology optimization of the model is carried out to obtain the material density distribution map when the structural material volume is smaller than the original structure and the structural stiffness is the largest, and then the pipe structural parts are arranged according to the material density distribution map. According to the material properties of the seat frame, a new finite element model is established, and the mechan...

Abstract

The invention relates to a component distribution method for an automobile seat framework. The component distribution method for the automobile seat framework comprises the steps that a design model is established according to the design request of the seat framework, and a design area is determined; a finite element model of the automobile seat framework is established according to the design area and loading conditions; topological optimization design is conducted on the finite element model with a variable density method, and a material density distribution diagram in the design area is obtained; pipe structural parts of the automobile seat framework are arranged based on the material density distribution diagram. The reasonable material density distribution diagram is obtained by establishing the finite element model for the design area, the pipe structural parts are distributed and arranged based on a material density method, and the purposes that under the premise that the safety of the automobile seat framework is met, the weight of the pipe structural parts is reduced, and the rigidity and the strength of the pipe structural parts are improved are achieved. The lightweight design of the automobile seat framework is achieved, and good economical efficiency can be obtained.

Description

technical field [0001] The invention relates to a manufacturing method of a product, in particular to a component distribution method of an automobile seat frame. Background technique [0002] The car seat frame is the core component of the car seat. In order to ensure the safety of the occupants, it must meet the requirements of dynamic and static strength and stiffness. At the same time, the car seat frame is the main part of the seat quality, and a reasonable seat frame structure must achieve light weight as much as possible under the premise of satisfying safety, so as to obtain good economy. [0003] In order to realize the lightweight design of the seat frame, it is first necessary to arrange the structural materials reasonably. The seat frame is generally composed of plate structural parts, pipe structural parts and connectors. In the skeleton backrest, the pipe structural parts are the main bearing parts to ensure the structural rigidity and strength. Therefore, the...
