오일러 매개변수를 이용한 연약지반 시험집광기의 동력학 해석

Abstract

A New method for dynamic analysis of an tracked vehicle on extremely soft soil is developed by using euler parameter. This vehicle assumed as a rigid-body with 6-dof. Cohesive soft soil is modeled through relations: pressure to sinkage, shear displacement to shear stress, and shear to dynamic sinkage. The orientation of vehicle is defined as four euler parameter. Euler parameter method is implemented effectively in an incremental -iterative algorithm for Dynamic analysis. The normalization of euler parameters constraints is satisfied by using of a sequential updating method.
