Movement conversion nonlinear modeling and simulation of precision line transmission products

Aiming at the nonlinear transmission problem resulting from movement conversion of line transmission products in aircraft electric serve system, in order to define the serve system states all the time, and then improve the precision of the mathematical model. With fork structure and rocker arm structure as the research objects, firstly, applying speed synthesis theory and structure force balance theory, the uniform nonlinear transmission ratio model are obtained respectively. Secondly, By means of modeling and analysis of the nonlinear transmission ratio, and utilizing computer aided model, the quantitative relationship between the transmission ratio nonlinear term and structure size is calculated. Finally, the dynamic model of serve system including transmission ratio is modeled, and the dynamic properties of the two structure forms are simulated by using MATLAB software, then the quantitative errors by using constant ratio instead of nonlinear ratio are calculated. The research results summarize the different nonlinear transmission characteristics and the range of application, which provide theoretical basis for the determination of electrical serve system structure form and size.
