In order to investigate stress distribution of side plates on the logging truck’s cable reel, and find the cause of side plates cracking, an elastic-plastic finite element model of three-dimension is set up. Based on a series of computations, the distributions of displacement and equivalent stress under the working conditions are analyzed, as well as the influence of the number of side plate floors on stress distribution. The results indicate the maximum equivalent stress is on the outside connection between side plate and cable reel, and the floors take the most part loads from steel cables. When the number of floors is greater than 11, increasing the floor number will not decrease the maximum equivalent stress obviously. The conclusion provides useful method and foundation for resolving floor cracking on logging trucks.

Q43Y-85D type crocodile hydraulic clipping machine was taken as research object to optimization design. A finite element model for clipping machine was built using shell unit as fundamental unit. ANSYS12.0 finite element method was used to analyze the deformation and stress distribution of the shear platform model of hydraulic clipping machine. The result showed that the maximum equivalent stress at the dangerous area was 368.162 MPa and the maximum elastic strain was 0.1814×10-2 mm. After the structural optimization design, it was found that the maximum equivalent stress decreased to 186.238 MPa which did not exceed the material’s yield limitation 215 MPa and the maximum elastic strain decreased to 0.919×10-3 mm which satisfied the requirement of stiffness.

The Stability

When performing anterolateral foraminotomy for the treatment of cervical spondylotic radiculopathy, the extent of uncinate process resection affects the stability of the cervical spine. The aim of this study was to determine the stability of the cervical spine after resection of various amounts of the uncinate process. Based on computed tomography (CT) scans of an adult male volunteer, a three-dimensional geometric model of the cervical spine (C4-C6) was established using Mimics 13.1, SolidWorks 2012, and ANSYS 15.0 software packages. Next, the mechanical parameters of the tissues were assigned according to their different material characteristics. Using the tetrahedral mesh method, a three-dimensional finite element model of the cervical spine was then established. In modeling uncinated process resection, two excision protocols were compared. The first excision protocol, protocol A, mimicked the extent of resection used in current clinical surgical practice. The second excision protocol, protocol B, employed an optimal resection extent as predicted by the finite element model. Protocols A and B were then used to resect the left uncinate process of the C5 vertebra to either 50% or 60% of the total height of the uncinate process. The stability of the cervical spine was assessed by evaluating values of deformation and maximum equivalent stress during extension, flexion, lateral bending, and rotation. After protocol A resection, the total deformation was increased as was the maximum equivalent stress during left and right rotation. After protocol B resection, the total deformation was little changed and the maximum equivalent stress was visibly decreased during left and right rotation. As evidenced by these results, protocol B resection had relatively little effect on the stability of the cervical spine, suggesting that resection utilizing the limits proposed in protocol B appears to better maintain the stability of the cervical spine when compared with current clinical surgical practice as replicated in protocol A.

Optimization method was applied to obtain optimal television packaging cushion for reducing drop impact response on television. At first, by establishing the parametric finite element model of television with packaging, the drop simulation was performed, and the equivalent stress distribution, acceleration response curve and other related parameters were obtained. Simulation shows that maximum acceleration is overload. Then, structural optimization of television with packaging was performed. The equivalent stress distribution and acceleration curves of optimal packaging and without optimal packaging for the independent components were studied. The results show that maximum acceleration is reduced and the cushioning performance is enhanced.

The Finite Element Analysis

Strain clamp is an important connection device in guy tower. If the quality of the compression splicing position is unsatisfied, strain clamp tends to be damaged which may lead to the final collapse of a guy tower as well as huge economic lost. In this paper, stress distribution on the compressible tube and guy cable is analyzed by FEM, and a large equivalent stress of guy cable is applied to the compression splicing position. During this process, a finite element model of strain clamp is established for guy cables at compression splicing position, problems of elastic-plastic and contracting are studied and the whole compressing process of compressible position is simulated. The guy cable cracks easily at the position of compressible tube’s port, the inner part of the compressible tube has a larger equivalent stress than outside.

The deformation, total velocity distribution and equivalent stress distribution were predicted. The numerical simulation results showed that the finite element analysis could exactly describe the plastic deformation and stress distribution during the forming process.

The purpose of this study was to evaluate the influence of the stress/strain distribution in buccal bone of an anterior maxillary implant using 3 bone thicknesses under 5 different loading angles. Different testing conditions incorporating 3 buccal bone thicknesses, 3 bone compositions, and 5 loading angles of an anterior maxillary implant were applied in order to investigate the resultant stress/strain distribution with finite element analysis. The maximum equivalent stress/strain increased with the decreasing of loading angle relative to the long axis. In addition to loading angle, bone quality and quantity also influenced resultant stress distribution. Dental practitioners should consider combinations of bone composition, diameter, and load angulations to predict success or failure for a given implant length and diameter.

In this paper, the static mechanical properties of a spherical magnetically suspending rotor are studied based on the finite element analysis method. The structure of the spherical magnetically suspending rotor is designed. The characteristics of the spherical magnetically suspending rotor are analysed and the necessity of static analysis is pointed out. The main content and general flow of statics analysis are discussed. The two working modes (GUI mode and command flow mode based on APDL) of the finite element software ANSYS are compared and analysed. Then the finite element model of the spherical magnetically suspending rotor is established by the command flow method, and the detailed modelling steps are given. On this basis, the static characteristics of the spherical magnetically suspending rotor are simulated and analysed. The simulation results show that the maximum equivalent stress and rigid body displacement of the rotor are within the safety threshold at a design speed of 10000rpm.

Based on the actual parameters of the capacitor energy storage cabinet on the top of the monorail train, built the cabinet’s finite element model. Then, according to EN 12663-1, set the calibration conditions and fatigue working conditions. Carried out the simulation calculation under different conditions, respectively. The calculation results under the static calibration conditions show that the maximum equivalent stress of each node on the model is smaller than the allowable stress under all working conditions. Therefore, the static strength of the cabinet meets the design requirements. Plotted Goodman fatigue limit diagrams of the cabinet’s base metal and weld and modified them in the Smith form. Then plotted the average stress and stress amplitude under fatigue working conditions in the corresponding scatter diagram. The diagram s show that all points are located within the permitted area. The results show that the fatigue strength of the cabinet meets the requirements of design and use.
