Sensitivity Analysis Application for Multibody System Synthesis

Abstract

Nowadays computational techniques utilization is essential part of the technical development. Visual form of data acquisition from simulations or solving of technical problems is the most effective approach. In the field of computer-aided design (CAD) 3D graphic visualization is certaintybecause it makes it possible to design a very complicated parts and devices at a short time. Furthermore it enable to trace how these parts behave during operating regimes and make an optimization of required parameters. In this paper the engineering design of gravity orienting part tool for cylindrical bushings will be presented. Each of 3D components was designed in CAD software Pro/ENGINEER and MSC.ADAMS virtual prototype was created in simulation software. Using the tools of parametric analysis for refining model parameters in software MSC.ADAMS optimization of selected design and dynamic parameters of given designed system was carried out.

Analysis and synthesis parameters influencing to the effects of impact

“…Mutual penetration of the body surfaces is monitored by the gap function g, whose positive value indicates penetration. A positive value of the normal contact force in turn means that it is trying to separate the bodies, and its value is non-zero while the surfaces are in contact [4].…”

“…The value of the penalty parameter is ensured, that the penetration of one geometry to another is small. However, the large values can cause difficulties in numerical integration [1,4,8]. Creators of the set value 1E6 is suitable for systems modeled in kg-mm-sec.…”

Kinematic analysis of Stirling engine

“…In the case of kinematic analysis of planar as well as spatial mechanisms [1][2][3] and their simulations [4][5][6], it is possible to use the specific software Matlab program. The advantage of this program is based on the simplicity of programing process, while the obtained results are high accurate in relation to the numerical equation solutions in the whole range of the mechanism movement.…”

Kinematic and dynamic analysis and distribution of stress for six-item mechanism

“…1) consists of six bodies and it was used as computational model. Using the kinematic analysis [4][5][6] and dynamic analysis and subsequent simulation [1][2][3], the main objective is connected with the determination and entering of the position domains, speed (velocity) domains as well as acceleration of the individual bodies in relation to the specified input values of the angular velocity for the driving body designated as 2. The angular velocity for the body, designated as 2, is specified in this way: ω 21 =1 °/s and α 21 =0.7 °/s 2 , where ω 21 =1 °/s is not constant and it is changed in dependence on time (Fig.…”
