The Finite Element Analysis

Recently various types of sandwich panel are applied for constructing bridge and ship structures. Sandwich panel is material that consists of lightweight core material and two metal faceplates. The application of sandwich panel in ship structures makes the structure less-complex and ship’s selfweight lighter because of the reduction of secondary stiffeners. This paper discusses sandwich panel that was fabricated using synthetic resin core material and two steel faceplates. This study is aimed to analyze stresses developed in the sandwich panel of 750 GT Ro-Ro ship car deck structure when it was subjected to the deck design load. The finite element analysis was carried out to obtain the stress distribution and maximum deformation on the car deck structures. The stress of the ship car deck constructed using conventional steel structure, i.e. steel plate and stiffener, was compared with the stress of the deck that was built using sandwich panel.

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.

Due to the limitation conditions of computer hardware in the past, the structure members need to be simplified in order to save the computing resources during the finite element analysis (FEA). During FEA of Steel joints, the simplified model is considered as hinge joint, rigid joint or half-rigid joint, which is different with the actual force. With the improvement of computer technology and hardware, actual finite element analysis method (AFEA) is proposed in consider of influence of actual model, welding, plate size and bolts, which is a more acceptable method in Precision compared with last.

Accurately predicting the burst strength is very important in the casing design for the oil and gas industry. In this paper, finite element analysis is performed for an infinitely long thick walled casing with geometrical imperfections subjected to internal pressure. A comparison with a series of full-scale experiments was conducted to verify the accuracy and reliability of the finite element analysis. Furthermore, three predictive equations were evaluated using the test data, and the Klever equation was concluded to give the most accurate prediction of burst strength. The finite element analysis was then extended to study the effects of major factors on the casing burst strength. Results showed that the initial eccentricity and material hardening parameter had important effects on the burst strength, while the effect of the initial ovality was small.

Conventionally, the influence of guy wire and wind load on derrick was often ignored in the static strength analysis of derrick of truck-mounted workover rig, it does not accord with the actual working conditions. This paper made the finite element analysis for one derrick of Truck-mounted workover rig through ABAQUS software. The author derive the maximum static hock load which derrick can bear, and reasonably shorten projective radius of guy wire, under different static hock load and wind load, determining the weakest position of derrick. Truck-mounted workover rigs are widely used in the filed of workover and drilling operation, due to their characteristic of power maneuverability and convenient to use. Derrick is the mainly working part of workover rig, as well as the weak links of workover. In order to guarantee relatively high security performance, we should accurately make simulated calculation for carrying capacity of derrick in the process of designing. The author derive the maximum static hock load which derrick can bear, and reasonably shorten projective radius of guy wire, by using the ABAQUS FEM system, apply for statics analysis of derrick under different static hock load and wind load.
