Modeling Software

The geometric models of the hydraulic turnover device are constructed by using three -dimensional modeling software UG, and then they are induced into simulation software ADAMS by a sharing data format. By using ADAMS, models are further simplified and the virtual prototype is established. By using the associated model, the simulation of the hydraulic turnover device is analyzed in ADAMS. Compared with the traditional methods of using physical prototypes, the movement processes and relevant parameters of the hydraulic turnover device can be effectively obtained by means of this method. Furthermore, the quality of the constraint relations between the parts is very important in terms of the accuracy of the model simulation analysis. This simulation results accord with the practical situation, which indicates that the operation is stable and the efficiency is high. It provides a theoretical basis for the practical design of the hydraulic turnover device, which shows that the combination of ADAMS and UG works well.

Despite efficiency of modern implantology, unplanned perforation and drill deviation could be happened during freehand placement. The aim of this study was to provide a methodology for fabricating dental surgical drill guide for fully edentulous patients while it was flexible in term of changing drill diameter. The data of patient consisted of bone anatomy and radio-opaque template obtained from computed tomography. Jawbone and radio-opaque template three dimensional models converted into a three dimensional modeling software by means of an image processing package. Based on jawbone anatomy and radio-opaque template, implantation plan and design of surgical guides were carried out in three dimensional software. Rapid prototyping technique was used to manufacture several surgical guides to be used in different drilling sequences. Finally stainless steel tubes were accommodated passage of drill. Sequential surgical guides were different only in terms of the metal tubes internal diameter. This provides the ability of changing diameter of the implant or drill after fabricating surgical guide.

According to the insufficient force analysis of the cable in the process of winch retraction, especially the insufficient research on the flexible cable retraction process such as the UHMWPE cable, the dynamic simulation analysis of the retraction process of the parallel grooved multi-layer drum and UHMWPE cable cable is carried out by using the virtual prototype software ADAMS. The simulation model of the cable is created by using the macro command program, and the virtual prototype model of the cable drum is completed, and the force changes of the cable under different rotating speeds are simulated.The simulation results show that the contact force between the cable and the double winding drum can be quickly stable under the specific load, and with the increase of the rotating speed, the maximum value of the tension change of the cable increases, but it is finally stable at a fixed value. The results can provide some reference for structural strength calculation of cable storage drum, selection of high molecular polyethylene cable and dynamic analysis of cable arranger under load.

To Receive

Among the studies done with rodents, the behavioral ones stand out. To perform these studies, the behavioral boxes are commonly used. These are devices in which the rodents perform some task to receive a reward. These animals are considered excellent subjects for studying the tactile sensory system, since they use their whiskers to locate and discriminate objects. In this work the goal is studying the sensory system of rodents in tasks in which the animals must discriminate the width of an aperture, using only their whiskers to receive a reward. We aim to develop an automated open-hardware behavioral box to perform task of tactile discrimination in rodents. For such, we designed the box using a three-dimensional modeling software and its control is implemented with Arduino, which was tested in a computer model trhough physical simulation. All used components are low cost and can be found or developed in Brazil. The present study provides an important tool for the study of the tactile sensory system, that makes possible other laboratories to build their own behavior box for tactile studies.

Very complicated as the cycloid wheel movement appears, tridimensional software Solid Works is applied to outer planetary cycloid wheel parts modeling and dynamic simulation with the outcome meeting the prospective design requirements. Therefore, we conclude that tridimensional modeling will be applicable for mechanical designing with great significance. In response to increasingly complicated product designing, the roles of the tridimensional modeling approach will be brought into fuller play. In pin-cycloid gearing, due to the specially curved and differential gear surface, the gearing accuracy and service life of the pin-cycloid are both affected. To get a smooth solution to the problem of the tridimensional surface shaping, priority shall be given to precise drawing of the gears profile curve [.

It has long been known that there are fractals, which construction resolve into cutting out of elements from lines, curves or geometric shapes according to a certain law. If the fractal is completely self-similar, its dimensionality is reduced relative to the original object and usually becomes fractional. The whole fractal is often decomposing into a set of separate elements, organized in the space of corresponding dimension. German mathematician Georg Cantor was among the first to propose such fractal set in the late 19th century. Later in the early 20th century polish mathematician Vaclav Sierpinski described the Sierpinski carpet – one of the variants for the Cantor set generalization onto a two-dimensional space. At a later date the Austrian Karl Menger created a three-dimensional analogue of the Sierpinski fractal. Similar sets differ in a number of parameters from other fractals, and therefore must be considered separately. In this paper it has been proposed to call these fractals as i-fractals (from the Latin interfican – cut). The emphasis is on the three-dimensional i-fractals, created based on the Cantor and Sierpinski principles and other fractal dependencies. Mathematics of spatial fractal sets is very difficult to understand, therefore, were used computer models developed in the three-dimensional modeling software SolidWorks and COMPASS, the obtained data were processing using mathematical programs. Using fractal principles it is possible to create a large number of i-fractals’ three dimensional models therefore important research objectives include such objects’ classification development. In addition, were analyzed i-fractals’ geometry features, and proposed general principles for their creation.
