<p>Spare Wheel Carrier is a component that must exists in a heavy duty vehicle. The function of this part is to store additional wheel in order to deal with punctures that might happen to the tire. This part is usually placed in the middle of the vehicle in order to maintain the position of center of gravity of the vehicle. The purpose of this research is to analyze the strength of SAPH 440 as the manufacturing material of the Spare Wheel Carrier from one automotive company. The Spare Wheel Carrier will endure a load of a replacement tire for its entire cyclic load. The load itself will generate stresses and strains in the part, especially in the welding joint. Therefore, the analysis is to be done to provide the automotive company with the result to determine improvement that should be made. The method that is used in this research is using CATIA software to create the three dimensional model of the part. Later, we import the model to ANSYS software to analyze the equivalent stress, equivalent elastic strain, directional deformation, and cyclic load for steady load, live load, and shock load. The calculation shows that the part can endure the force from steady load, with the estimated cyclic load of 70,723 cycles. But for live load, the stress and strain will be happening around the yield strength and offset yield strength and the estimated cyclic load declining significantly to 6,358.6 cycles. Furthermore, the shock load result stated that the stress and the strain are exceeding the yield strength and reduces the estimated cyclic load to 1,843.9 cycles. In conclusion, the material is proven to be safe for usage as the Spare Wheel Carrier manufacturing material.<br />Keywords. spare wheel carrier, SAPH 440, stress, strain, deformation, cyclic load</p>

The purpose of this study was to investigate the influence of Temporomandibular Joint implant geometry on stress distribution in total reconstruction of temporomandibular joint. A three dimensional model of a lower jaw of a patient was developed from a Computed Tomography scan images. Anatomical curvature and flat contact surface of implant design and fixation screws were modeled. Two implanted mandibles were then compared by means of finite element analysis. The muscle forces for incisal clenching were applied. The equivalent stress resulted in contact surface region of the bone and implant and in fixation screw holes were investigated to evaluate the designs. In applied loading condition, The results showed that anatomical design of implant was more preferred and it will lead to long-term success of implant.

Study Results

By using the geometry modeling software Pro/E, the three-dimensional model of hydraulic shield support has been built. Considering of the loading conditions and displacement constraints which the hydraulic shield support suffers from under the actual working conditions, the static strength and fatigue strength of the hydraulic shield support were analyzed by FEM when they were in two different typical working conditions of the support height, and the weakest part which was discovered in the analysis was improved in its structure. The study results showed that the designed hydraulic shield support could meet the requests of the static strength and fatigue strength. The column of the hydraulic shield support and the ear plate which locates in the connection area of the column and the push beam are the weakest parts. The counterforce given by the ground mainly focuses on the mid-back position of the hydraulic shield support, which meets the requirements of saving labor when they were removed. In the Finite Element Analysis when the reinforcement ribs were added to the ear plate, we found that the maximum equivalent stress is reduced by 150 MPa and the fatigue life coefficient is reduced markedly as well. The possibility of the fatigue breakage was decreased largely after the structure was modified and the service life of the hydraulic shield support was improved. These prove that the improvement of the hydraulic shield support structure is reasonable and feasible.

Comparison Results

This paper establishes the two-dimensional model, three-dimensional simplified model and three-dimensional of the single-screw pump stators ,and accomplishes their displacement and stress analysis in even pressure inside the stator using ANSYS software. This paper analyzes the comparison results of the combined displacement, equivalent stress and shear stress cloud in the XY plane of single screw pump stator’s three different models. The results manifest the significant differences of the three models for finite element analysis. This study validates that finite element analysis of three-dimensional model leads closer to the true situation.

Materials Used

The purpose of this study was to develop a new three-dimensional model of an osseointegrated molar dental prosthesis and to carry out finite element analysis to evaluate stress distributions and intensities in the bone and in the components of dental prosthesis under three loads (corono-apical, distal-mesial and buccal-lingual) were applied to the top of the occlusal face of the prosthesis crown. The interfacial stresses were also determined inside and outside of the threading when the dental prosthesis system was subjected to one of three masticatory loads. All materials used in the models were considered to be isotropic, homogeneous and linearly elastic. The elastic properties, loads and constraints used in the model were taken from published data. In this study, the stress concentration occurred around the threaded dental implant neck. Thus, this area should be preserved clinically in order to maintain the bone–implant interface structurally and functionally.

The Impact

This article treats the pile driving as multi-body dynamic contacts. By using the penalty function method and three-dimensional model of finite-element method, the dynamic process of pile driving is acquired and a method for choosing the cushion material of the hydraulic pile hammer to improve driving efficiency is proposed. The process of pile driving in the real situation of an industrial experiment is simulated. The results of stress on test point are consistent with the test point. By analysing the stress distributed along the direction of pile radius and pile axis, the rule of the stress distribution on the pile is concluded. The rule for cushion material choice is obtained by comparing the influence for the impact stress with different elastic modulus ratio of the hammer cushion to the pile and the pile cushion to the pile.

Element Approach

A finite element approach based on Ansys is developed to simulate stress intensity distribution in a three dimensional model of coupling clamp joint, which includes ferrules, pipe caps and bolts. The characteristics of stress intensity distributions of coupling clamp joint under strength pressure loading have been studied by means of the non-linear finite element method. The FE model can also predict the clamp quality and tolerances to be expected under different process conditions and define the most effective process parameters to influence the tolerances. The study could give us a better understanding on the mechanism and basis for optimization design of the coupling clamp joint.

New full hall scaffolds with pulley-clip style formwork support system is adopted in the concert hall of Changsha. This paper presents the concept of the complete equivalent initial imperfection according to the characteristics of too many influential factors on the high formwork supporting frame，then makes the complete equivalent initial imperfectione equivalent to assumed equivalent horizontal load in order to ensure the safety of the frame. At the same time, it gets a three-dimensional model by the general finite element software ANSYS 10.0. Based on the results of experiment and finite element analysis, it gets the recommended value of assumed equivalent horizontal load. The study on the high formwork supporting frame with pulley-clip style provides some reference for other similar projects.
