“…Results are obtained in form of time diagram of the desired variables. Tasks are solved numerically; the model is compiled using program MSC Adams View [4], [5]. The results obtained by the simulation of four-member mechanism of the crank rocker mechanism were processed by the postprocessor program of MSC Adams/View.…”

The aim of this article is to develop a functional model of crank rocker mechanism in ADAMS/View software and subsequent complete kinematics analysis hereof. We analyze the movement of the members of the mechanism. The kinematic analysis was performed analytically and graphically. The mechanism has been modeled too and solution was drafted in the program MSC ADAMS/View. The next stage is the simulation with a set of different parameters to obtain its kinematic analysis. Finally, the data gathered in this process is compared and evaluated. Finally, the paper presents the results with graphical representation of parameters such as speed, distance and acceleration.

Transient thermal and residual stress fields in flux-cored arc welds were examined using a finite element (FE) model. Experimental multipass welds were produced using both conventional and low transformation temperature (LTT) filler metals. Temperature-dependent material properties and both convective and radiant heat loss boundary condition have been considered in the FE model. The effects of the transformation temperature and interpass intervals on residual stresses were examined. It was found that compressive longitudinal residual stresses were developed at the weld centreline in the LTT filler metal. A short-time interpass interval causes the weld fusion zone to be above the martensite start temperature allowing the optimal use of the phase transformation effect. The FE model is sensitive to alteration in welding parameters and can satisfactorily predict the residual stress distribution in welded parts.

“…In kinematics analysis of the mechanism of transport equipment is used, one of the most widely used multi-functional computing software in the world MSC Adams (Automatic Dynamic Analysis of Mechanical Systems). Program helps with simulation of mechanical systems consisting of more bodies, which are connected with each other by different types of kinematics linkages [6]. This software allows you to create dynamic, kinematics and static analysis of the proposed models of mechanical systems [5].…”

The aim of the thesis is the solution of kinematics analysis model of the conveyor with a crank mechanism. For solution is to use a graphical method for determining the kinematics parameters of the individual members of the mechanism. In part kinematics analysis is also used MSC Adams View program that is designed to address the problems of kinematics and dynamics of systems with more degrees of freedom. This program shows the displacement, velocity and acceleration and angular velocity and angular acceleration of members. Finally, the work presents the results with graphic display of parameters such as displacement, velocity and acceleration. Introductory chapters are devoted to general issues kinematics mechanisms and the following chapters are devoted to a particular model of the conveyor mechanism.
