Fea Model

The proposed finite element analysis (FEA) model was constructed using FEA simulation software, ANSYS program, for determining effects of corrosion fatigue (CF) from TIG welding process on AISI 304 stainless steel workpiece. The FEA model of TIG welding process was developed from Goldak's double ellipsoid moving heat source. In this paper, the residual stress results obtained from the FEA model were consistent with results from the X-ray diffraction (XRD) method. The residual stress was further used as an input in the next step of corrosion fatigue analysis. The predictive CF life result obtained from the FEA CF model were consistent with the value obtained from stress-life curve (S-N curve) from the reference literaturature. Therefore, the proposed FEA of CF model was then used for predicting the corrosion fatigue life on TIG welding workpiece, the results from the model showed the corrosion fatigue life of 1,794 cycles with testing condition of the frequency ( f ) = 0.1 Hz and the equivalent load of 67.5 kN (equal to 150 MPa) with R = 0.25.

The vice frame bears and transfers the forces and loads between the bogie and the vehicle body.The strength of the vice frame relates directly to the stability and smoothness of the vehicle. In this study, finite element analysis is utilized first to analyse the structural strength and fatigue life of the vice frame, and the recognize the weak parts of its structure in order to enhance its structural strength in the following design work.The finite element analysis is performed on a simulation software Ansys. Then an experiment is designed to test the fatigue strength of the vice frame. The experimental result indicates that the fatigue strength of the object corresponds to the standards and the finite element analysis has high feasibility in solving this kind of problem.

This subject is proposed via authentic market investigation, based on the sharp increase of household garbage in urban cities and urgent demand for environmental amelioration in recent years. Taking horizontal refuse compactor as an example, this paper optimizes the configuration of key components of refuse compactors, by employing Finite Element Analysis (FEA) method, aiming to select the most appropriate components to equip compactors, whose operation efficiency can be markedly enhanced. The statics analysis for each key component is individually conducted by applying ABAQUS, the FEA simulation software, to test the reliability of this new structure.

In view of large load, the shape of large crank forgings and forging process are designed reasonably. Large crank forging process is simulated by numerical simulation software DEFORM-3D to improve the forging process and the dies, including adding upsetting step and related dies. The result shows that improved process and dies can obtain higher quality finish forgings and the load reduces to a rational level, which provides basis for crank forging process and die design.

Visual inspections of selected semitrailers during routine equipment checks revealed that the kingpin bent in the direction of 180 degrees from the direction that the semitrailer is towed. Confirmation from semitrailer repair facilities found that in some cases the semitrailer’s supporting structure developed unexpected cracks. These cracks were not thought to be age related but were most likely caused by high stresses from unknown high loads. In an effort to determine the forces at the kingpin and fifthwheel, TruckSim® modeling and simulation software was utilized to predict the forces in all three directions during various operating maneuvers. Computer simulations suggest the largest forces are experienced during coupling operations as opposed to severe maneuvering or braking. The development of a Finite Element Analysis (FEA) model of the tractor-semitrailer coupling determined that high coupling speeds would overload the kingpin-fifthwheel structure. The FEA model also allowed researchers to determine that a damping system would lower the forces at the kingpin-fifthwheel interface to the magnitude of forces experienced during normal operations. A literature search found no valid documented tests, and determined the SAE J133 kingpin loading requirements were incorrect.

Abstract In the present paper, finite element analysis of the knee joint is performed for stress and strain estimation of the knee joint for osteoarthritis patients. Osteoarthritis (OA), called the wear and tear arthritis is commonly occurring arthritis wherein a gradual loss of cartilage from the joints are observed. This leads to the joint bones rubbing quite close against one another with less amount of shock-absorbing done by the cartilage causing pain, stiffness, swelling, decreased movability and bone spur formation can be observed. It is mostly observed in patients above 45 years old, but weight and gender are also some of the factors forcing a quick onset of the disease. Using modelling software Blender, a solid model is made of the bone component, namely tibia, fibula, femur and patella as well as Ligaments and cartilages. Using finite element simulation software, analysis is done to determine the level of stress under various forces on the joint. The knee joint experiences a maximum stress and strain of 2.352 MPa and 0.02454 respectively which are within safe static condition. The study can be further extended to predict the danger of failure for the patients having osteoarthritis conditions which in turn will help to take a preventive measure for the knee joint.

UG software was used to build the entity model for light truck driving axle housing, imported the model to ANSYS Workbench collaborative simulation software, and analyzed the stress after meshing and loading. It can be seen that the maximum equivalent stress of the drive axle housing under various conditions was less than the allowable stress value, and the evaluation index of vertical bending static strength experiment is Kn> 6, meeting the strength requirement; In the condition of full loads, the maximum deformation of the per-meter center distance is: 0.1 mm/m < 1.5 mm/m, also meeting the rigidity requirement; The experimental study is used to verify the analysis results referring the relative articles, shows that analysis results are reliable. This process provides reference for other driving axle housing and similar structure finite element analysis.
