Optimization of Multibody Systems Based on the Generalized-α Projection Method for DAEs

摘要：

Optimization strategy of multibody systems is developed in this paper.Augmented Lagrange method (ALM) is used to transform constrained optimal problem into unconstrained form firstly.Then methods based on second order sensitivity are used to solve the unconstrained problem, where the sensitivity is solved by hybrid method.Generalized-α method and generalized-α projection method for the differential-algebraic equations (DAEs) is presented to get state variables and adjoint variables during the optimization procedure.Numerical results validate the accuracy and efficiency of the methods presented.
