Comparative Research on the Explicit and Implicit Mechanical Calculation Method
Shows two kinds of numerical computation method for rigid-flexible dynamics equation and its developments. Based on the explicit nu-merical method, respectively solves i.e. Runge Kutta method and implicit numerical method, i.e. Newmark method, linear and nonlinear dynamics equations for curved beam pendulum and slider-crank mechanism. In condition of the same computation accuracy, results com-parison show that implicit numerical method computation efficiency is obviously higher than the explicit numerical method no matter for solving linear nor the nonlinear dynamics equation. So, the conclusion that implicit numerical method, i.e. Newmark method is recom-mended for calculating the mechanics problem in engineering.
