A kind of force measurement mechanism which can measure the two-directional transient impact load in the same time is introduced in this paper, and the analysis research of the mechanical part are followed. First, by using the pro/E software, the 3D concrete model of the force mechanism is contributed. Then, by means of the ANSYS finite element analysis software, its stiffness and strength are analyzed, and strain and deformation figures from different directions are obtained. The static maximum deformation and strain of the force measurement mechanism and its key components, and also the whole distribution are showed in the analysis results. The weak parts of the force measurement mechanism and its key components are also showed in this paper, which can be helpful for the further improvement and following actual tests [.1]

Gas Bearing

In order to reach the requirements of the newest generation of wire bonder, gas bearing positioning stage directly driven by voice coil actuators is designed.In the stage,an air decoupling mechanism is used. And the finite element analysis software ANSYS was used to analyze the static and dynamic characterizes of the stage so that the structure meets the requirement of stiffness,and at the same time,the moving parts are as light as possible. The simulated results show that the maximum deformation of work platform is in the work surface and the deformation is in request scope.,the deformation of decoupling mechanism is in the main driving rod contact, but this has a little influence on the stage.

The Impact

The finite element analysis method of falling-object protective structure (FOPS) for the loader is presented in this paper. Taking FOPS for CL958 type loader as an example, this paper builds the analysis model in ANSYS, obtains the displacement of the load center and the maximum deformation of FOPS caused by the impact load and proves the safety by the drop test. It provides the theoretical basis and design principle for the optimization design and reliability design of FOPS for the loader.

Safe Condition

This study is aimed at carrying out a finite element analysis on a roll cage of a vehicle used for student competitions around the world. The design process was carried out using a CAD package and analysis was done using finite element analysis software, ANSYS. Impact test was carried out on the roll cage under different conditions and the effect on the structural members are studied and discussed. The results are very much helpful and assure that the car is in safe condition in case of a crash or accident. Finite Element Analysis (FEA) is also carried out with the frame against torsional loading. Two different materials were considered for the analysis. The results of displacement of frame, nodal solution, element solution and bending moment are discussed.

Biological Selection

The study obtains a methodology for the bionic design of the tower for wind turbines. To verify the rationality of the biological selection, the Analytic Hierarchy Procedure (AHP) is applied to calculate the similarity between the bamboo and the tower. Creatively, a bionic bamboo tower (BBT) is presented, which is equipped with four reinforcement ribs and five flanges. Further, finite element analysis is employed to comparatively investigate the performance of the BBT and the original tower (OT) in the static and dynamic. Through the investigation, it is suggested that the maximum deformation and maximum stress can be reduced by 5.93 and 13.75% of the BBT. Moreover, this approach results in 3% and 1.1% increase respectively in the First two natural frequencies and overall stability.

Large Container

The emerging global economic needs are driving the designs for the next generation of ocean going vessels. Current ultra-large container carrier (10,000 TEU plus) designs are considerably larger and more complex than any currently in service. Proper and rational classification assessment requires that first principles based direct calculation methods be used to augment the standard classification review. The design philosophy behind the ABS Dynamic Loading Approach enables comprehensive identification of potential failure mechanisms. The scope of the necessary engineering assessment encompass full-ship finite element analysis under non-linear sea loads, spectral fatigue analysis, finite element lashing analysis, free and forced vibration analysis, and transient and impact load analysis. This paper describes key aspects of the DLA design philosophy such as non-linear sea loads, load combinations, various applications derived from full-ship finite element analysis. Several examples are given to highlight some critical failure mechanisms to be considered for ultra-large container carriers.
