This paper deals with the effect of splicing area design parameters on the mechanical behavior of beam-column connection with cantilever beam splicing. A series of models are designed based on the change of parameters. The mechanical behavior of beam-column connection with cantilever beam splicing is systematically studied by using the finite element analysis. The analysis results show that the number and arrangement of web bolt will have a great influence on mechanical behavior of the splicing joint when the number of flange bolt is designed by the precise design method; the number and arrangement of web bolt will have a less influence when the number of flange bolt is designed by the equal strength design method; Splicing area design parameters have little effect on the ultimate load and the initial rotational stiffness of the splicing joint; the number and arrangement of bolt is sensitive parameter for yield load of the splicing joint and the rotational stiffness in the the splicing area.

Trajectory Matching

This study addresses the problem in designing pneu-net actuators to achieve specific target trajectories for particular applications. The finite element analysis (FEA) method is used to study the sensitivity of 9 design parameters to bending deformation of actuators, and the results of FEA demonstrate that the width of the chamber and the width of the middle layer have great influence on the bending performance. Besides, the relations between the bending angles of actuators with different width parameters and the pressure are always highly linear. Using FEA and the cubic polynomial fitting algorithm, a unified bending model of the pneu-net actuator is established with three crucial design parameters (i.e., segment length, chamber width, and middle-layer width). An optimum design method based on the bending model and genetic algorithm (GA) is put forward to automatically adjust these three crucial parameters to realise trajectory matching. The method is developed to be an effective solution for the problem in matching the target trajectory with the experimental results achieved on an actuator designed by imitating a human index finger. Furthermore, the results of the experiment also verify that the actuator can achieve stable grasping, and the proposed method has an important directive to design pneu-net actuators for their application in the fields of robotics, rescue, and detection.

The micro-model, which the brick and the mortar model are separated, is used to analyze masonry. Meanwhile, the mortar is divided into three layers along the thickness direction to obtain the internal mechanical behavior of mortar, and the vertical mortar joint strength is taken as 50% strength of the horizontal mortar joint for considering the poor quality of vertical mortar joint. The compressive ultimate load and failure mode of masonry taken from the finite element analysis result, especially the vertical cracks throughout all bricks and mortar and change of brick and mortar strain, are in agreement with the experimental results. It shows that the micro-model and method adopted in paper are able to effectively apply in nonlinear structural analysis for masonry.

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.

This paper introduces a optimize design method of ship unloader. The traditional structure design method is totally by experience and manual calculation, while this method is using the Finite Element Analysis (FEA) method to optimize the structure of ship unloader. Therefore this method may keep the stress and deformation of the structure under permission with less use of materials. First we use the FEA analysis software ANSYS to analyze the static strength and stiffness of grab ship unloader, and get its stress and deformation under different work conditions. Then we evaluate the results and modify the structures to improve the performances of the structure under the complex working conditions. Case study shows this method is effective and efficient in practical use.
