Error Analysis of a Stewart Platform
نویسندگان
چکیده
The use of parallel structures, such as a Stewart platform (SP), for machine tools is a current trend. Some powerful analytical tools are needed to analyse the effect of errors in parallel structures. A model of a SP was analysed to include all the sources of errors [1]. We developed a similar error model to a Stewart platform and a Modified Stewart platform (MSP). Both SP and MSP designs have the same error models. The model developed here is intended for the design of a controller to reduce the effects of the errors due to temperature and stress state of the material.

Gyroscope Drift Error Analysis in the Position-Independent Navigation Algorithm of a stable platform Inertial System
This paper deals with analyzing gyroscope drift error in the position-independent navigation algorithm of a stable platform inertial system. Most of the stable platform navigation algorithms proposed in the literature have drawbacks of estimating position rates for alignment commands. Not only the estimating position rates are the basic source of position errors, but they also make the alignmen...

Modeling and Wrench feasible workspace analysis of a spatial cable suspended robots is presented. A six-cable spatial cable robot is used the same as Stewart robots. Due to slow motion of the robot we suppose the motion as pseudostatic and kinetostatic modeling is performed. Various workspaces are defined and the results of simulation are presented on the basis of various workspaces and app...

متن کاملExperimental Investigations on the Contour Generation of a Reconfigurable Stewart Platform
Reconfiguration of Stewart platform for varying tasks accentuates the importance for determination of optimum geometry catering to the specified task. The authors in their earlier work (Satheesh et al., 2008) have indicated the non availability of an efficient holistic methodology for determining the optimum geometry. Further, they have proposed a solution using the variable geometry approach t...
