Design of multifunctional self-balancing nursing bed based on SolidWorks

I. Introduction

Based on the three-dimensional parametric design process of SolidWorks , this paper combines in-depth analysis of parametric design, assembly and motion simulation, workspace analysis and kinematics analysis. This article completely abandons the parametric design idea, but focuses on the practical problems of multi-functional nursing beds. This solution is also applicable to the development of other similar medical nursing equipment.

This article will elaborate on some key issues in the design process of the multifunctional automatic balance nursing bed, and will not repeat the content of the parametric modeling and other aspects introduced in the current related literature.

2. SolidWorks 3D design process

At present, there are many articles about the design of SolidWorks in medical beds and nursing beds. Most of them focus on part modeling, virtual assembly, motion simulation, and finite element analysis of parts. They only highlight the characteristics of SolidWorks software or a certain nursing. The local function of the bed has not been systematically studied with the design of the multifunctional nursing bed as the core. SolidWorks is just a tool, and the tool must serve the design object, which is what we emphasize in the design process.

Figure 1 is a technical flowchart of three-dimensional design in SolidWorks, the main body of this process is a parallel design process. In this process, the design plan is determined first, followed by 3D modeling and modeling, and the main focus is on the part modeling. After the modeling is completed, it is assembled, and static interference analysis and local modification are performed. After confirming the plan, conduct motion simulation analysis to modify the dynamic interference that occurs during the motion. After confirming the basic dimensions, a finite element analysis can be performed on the key components to determine whether their mechanical characteristics meet the work requirements, and structural optimization is carried out on this basis. After optimization, the finite element analysis needs to be conducted again until the final plan is determined. Two-dimensional drawing and processing are some follow-up work, skipped here.
