The overall three-dimensional parametric model of the crankshaft has been completed based on the ANSYS Parametric Design Language (APDL) from the software of ANSYS and by combing the structure analysis capability with the statistical analysis capability of its PDS module, the reliability analysis of Monte Carlo finite element method (FEM) will be achieved according to the finite element analysis technology and the reliability basic principles. The 4110 diesel engine crankshaft was taken as an example, the parametric design will be introduced into the finite element structure analysis to implement the rapid adjustment of the structure parameter, produce the anatomic model automatically and complete the process of the structural analysis and reliability analysis. The process that the reliability analysis of the crankshaft has been realized will be described in detail. According to the results of probability analysis, the sensitivity relation between the design variable and the object variable will be obtained and at the same time the maximum stress probability distribution function of these dangerous parts and the main affective factor for object variable will be given, which will offer the useful data for the structure reliability optimization design.

In the rubber mixing production line, because of the traditional design method, the stiffness of the small arm of feed mechanism is usually not enough and the reserve of strength and weight is surplus. To solve the above problems, we optimized the arm structure with the optimization design module of the finite element analysis software. Based on the structure theory and optimization design theory, the three-dimensional model and the proper optimization model been established with the three-dimensional software and finite element analysis software. The total weight of the small arm is used as the objective of optimization and the dimensions of each parts is used as the design variables. Under the precondition of requirements of strength and stiffness, the optimal solution of these dimensions is figured out. Analysis shows that the method of structure optimization is feasible. This method provides an important reference for the optimization design of feed mechanism's small arm and similar parts.

Rehabilitation with implant prostheses in posterior areas requires the maximum number of possible implants due to the greater masticatory load of the region. However, the necessary minimum requirements are not always present in full. This project analyzed the minimum principal stresses (TMiP, representative of the compressive stress) to the friable structures, specifically the vestibular face of the cortical bone and the vestibular and internal/lingual face of the medullary bone. The experimental groups were as follows: the regular splinted group (GR), with a conventional infrastructure on 3 regular-length Morse taper implants (4 × 11 mm); and the regular pontic group (GP), with a pontic infrastructure on 2 regular-length Morse taper implants (4 × 11 mm). The results showed that the TMiP of the cortical and medullary bones were greater for the GP in regions surrounding the implants (especially in the cervical and apical areas of the same region) but they did not reach bone damage levels, at least under the loads applied in this study. It was concluded that greater stress observed in the GP demonstrates greater fragility with this modality of rehabilitation; this should draw the professional's attention to possible biomechanical implications. Whenever possible, professionals should give preference to use of a greater number of implants in the rehabilitation system, with a focus on preserving the supporting tissue with the generation of less intense stresses.

Abstract The paper describes the intention of the authors to determine whether it is possible to predict relative belt edge endurance for radial passenger car tires using the finite element method. Three groups of tires with different belt edge configurations were tested on a fleet test in an attempt to validate predictions from the finite element results. A two-dimensional, axisymmetric finite element analysis was first used to determine if the results from such an analysis, with emphasis on the shear deformations between the belts, could be used to predict a relative ranking for belt edge endurance. It is shown that such an analysis can lead to erroneous conclusions. A three-dimensional analysis in which tires are modeled under free rotation and static vertical loading was performed next. This approach resulted in an improvement in the quality of the correlations. The differences in the predicted values of various stress analysis parameters for the three belt edge configurations are studied and their implication on predicting belt edge endurance is discussed.
