Mechanical Elements Analysis of Stewart Platform: Computational Approach

Abstract

Because of the mechanical stress importance in the dynamic mechanisms, a Stewart platform is subjected to analysis to extract its critical stress areas in this study. The Stewart platform is an effective mechanism because it has been employed as a stabilizer or motion simulator. When this mechanism is subjected to static and dynamic forces in various applications, its components are at risk of failure in critical stress areas. This issue can be considered when designing, and parts failure can be prevented by knowing the essential points and stress values. This study is modeled the Stewart platform with specific dimensions and mechanical properties in Ansys Inc. and subjected it to static and Modal analysis with a numerical approach. The results present effective parameters that could be used in the mechanical design for this category of this platform.
