Electromechanical joint simulation analysis of two-dimensional precision high-speed turntable based on Adams and Amesim
To solve the position control accuracy problem of high-precision rotary tables,a two-dimensional precision high-speed rotary table was studied using Adams software to establish a dynamic model for simula-tion analysis.The model accuracy was evaluated based on the fixed angle retention effect,achieving dynamic simulation and analysis.In order to further improve the model retention accuracy,joint simulation was carried out using both Amesim and Adams software,with Adams software responsible for transmission calculation and solving,and Amesim software for position control.Compared with using only the dynamic model for simulation,the relative errors of the joint model simulation results at the retention angles of 60° and 120° were reduced to 0.13%and 0.09%,respectively,ensuring the accuracy of the joint model in the design or modifi-cation of two-dimensional precision high-speed rotary tables from the perspective of model accuracy.Finally,the transmission seat prototype was tested,and the actual retention angle of the prototype was recorded to verify the accuracy and precision of the joint model.
