Error Modeling for Structural Deformations of Multi-axis System Based on Svr
نویسندگان
چکیده
Multi-axis system is constituted by the mechanical links, and the link position load deformations are nonlinear. That is an important factor to affect the positioning accuracy of multi-axis system. As the nonlinear characteristics of link position and load deformations, a novel method for modeling deformations of loaded components based on SVR was presented. The 2R manipulator load deformations error models were building by ε-support vector regression, and according to the model, the trajectory error compensation was simulated. The simulation of structure deformations models and motion error compensation of 2R manipulator shows the SVR method could be used to build the deformations error model effectively.

When structures are subjected to strong ground motion excitations, structural elements may be prone to yielding, and consequently experience significant levels of inelastic behavior. The effects of inelastic behavior on the distribution of peak floor loads are not explicitly accounted for in current seismic code procedures. During recent years, many studies have been conducted to develop new de...
