The Finite Element Analysis

Several studies have been conducted to prevent neck injury in rear-end collision. The headrest of the seat which suppresses the relative motion of the head and the torso can suppress the extension of the head, thereby alleviating the injury. The active headrest has a mechanism that supports the head by deploying the headrest at the rear-end collision. The spring remains compressed or twisted until a collision signal is generated and the headrest is deployed after the collision signal. Depending on the shape and deployment structure of the spring, a spring design with a high resilience that is acceptable to the headrest is required. In this paper, design parameter of spiral spring suitable for the structure of the developed headrest is selected, prototypes are fabricated, and development parameters such as development time and development distance are checked and optimal design parameters of the spiral spring are derived. The feasibility of the headrest with the designed spiral spring was verified by the finite element analysis.

Simulation Results

Propeller is one of the critical parts in garbage powder mixer and affect significantly to the performance. In order to obtain a more reasonable structure, force analysis and stress analysis is carrier out for the propeller based on the actual working condition. Optimal design for the propeller is implemented by the results of stress analysis. To verify the rationality and feasibility of this mechanism, the finite element analysis for the propeller is performed by using the ANASYS software. The simulation results show that the maximum stress of the propeller is on the joint of blade and rod. The optimized propeller is satisfied with the strength requirements.

The Finite Element Analysis

For designing the wheelchair structure under the seat loading, the stresses and failure indexes in each ply of the composite laminate are obtained by the finite element analysis. Using the Tsai-Wu criterion and delamination criterion, the stacking sequence [04/904/454/-45]sis the final optimal design for the wheelchair frame. On the contrary, the uni-directional laminates, i.e. [9013] s, [4513] s and [-4513] s, are bad designs.

It introduced the application of the behavioral modeling technique and the finite element analysis to optimize the packaging container structure design. Here showed an example about a design process of a certain volume beverage bottle. Firstly, through determining the design targets, analysis the design parameters and iterated calculation for these parameters, the construction and dimension of the container which meet the design targets can be obtained initially. On this basis, the stress on the container can be emulated using finite element analysis. After the strength factor to be considered, the design proposal of the packaging container is the optimized one finally.
