Purpose. To estimate the calculation error in determining kinematic and dynamic characteristics of UT62 tubbing erector manipulator mechanism movement. Methodology. Modern computer analysis methods are used, which implemented a number computing complexes. Due to task complexity, mathematical model for fragment, is hydraulic cylinder with two degrees freedom, has been developed modeling. This us...

The paper describes the original robotic arm designed by our team kinematic design consisting of universal rotational modules (URM). philosophy modularity plays quite an important role when it comes to this mechanism since individual will be building blocks entire arm. This is a serial chain with six degrees freedom unlimited rotation. It was modeled in three different environments obtain neces...

Rangka adalah salah satu komponen penting yang harus dibentuk dalam konstruksi kuat untuk mendukung bobot kendaraan. Desain kendaraan kelas prototype tidak beroda empat dan diharuskan mengikuti desain empat. Faktor keamanan parameter utama menentukan kekuatan rangka mobil, sehingga faktor oleh melebihi 2 dapat diasumsikan aman. Tujuan dari kajian ini cocok jenis mobil SEM dengan software Solidw...

The new standard ISO 14649 provides CAD/CAPP/CAM/CNC with an interface and a comprehensive high level and detailed manufacturing information. CNC technology based on STEP-NC will be the future trend, and the intelligent process planning is the core of STEP-NC oriented CNC technology. The objective of this research is to present the architecture, key technologies and implementation of STEP-NC or...

Misalignment is an important cause for the early failure of large doubly-fed wind turbines (DFWT). For the non-stationary characteristics of the signals in the transmission system of DFWT and the reality that it is difficult to obtain a large number of fault samples, Solidworks and Adams are used to simulate the different operating conditions of the transmission system of the DFWT to obtain the...

Sketch-based modeling has attracted considerable attention in recent years. In this paper, we propose a semantic feature modeling system for sketch-based jewelry design, called Sketch2Jewelry. The newly devised semantic feature class encodes specific domain knowledge (jewelry design knowledge in this paper) and supplies prolific semantic information. The advantage of using semantic features is ...

A building design of vertical axis wind turbines (VAWT) was presented in the article. The construction and operating principle of a wind turbine were described therein. Two VAWT turbine models were compared, i.a. Darrieus and Lenz2, taking their strengths and weaknesses into consideration. 3D solid models of turbine components were presented with the use of SolidWorks software. Using CFD method...

The keel design of the tibial tray is essential for the transmission of the majority of the forces to the peripheral bone structures, which have better mechanical proprieties, thus reducing the risk of loosening. The aim of the present study was to compare the behaviour of different tibial tray designs submitted to torsional forces. Four different tibial components were modelled. The 3-D recons...

Isometric modification is proposed as a new method of axial modification of spur bevel gear. Based on the gear geometry theory and the normal meshing motion equation of gear pairs, changes of meshing points and angles are analyzed and the effect of axial modification on meshing movement of gear pairs is discussed. After that, a method of drawing spherical involute with the aid of SolidWorks sof...
