- Abstract
In order to improve the accuracy and efficiency of flexible multibody system dynamics simulation and control, the research on the selection of shape function in flexible multi- body system is needed.Under the specific floating coordinate system, deduce flexible multi-body system dynamics general equation based on Lagrange equation.Analysis and compare the coefficient matrix of dynamic equation In view of the three different types of shape function, the effect of shape function selection for dynamics calculation accuracy and efficiency is studied.Research shows that floating coordinate system affect the degree of equation coupling , and The main factors influencing the calculation accuracy and efficiency is shape functionThe form of Dynamics equation under static deformation assumption is the simplest and calculation efficiency is highest.Calculation efficiency of the finite element model and vibration mode model increases as the number of units and the number of mode truncation decreases.Calculation efficiency and accuracy interact on each other and determine the shape function of the form.
