PATAC VAA ADAMSVirtual Prototyping Technology ----Basic Training Contents Basic Concept Using Software Application Examples Basic Concept ADAMS : Automatic Dynamic Analysis Mechanical System Research Object：mechanical system Research Area：kinematics and dynamics Basic concept kinematics Study of motion of a system without regard to motivating forces All degrees of freedom are prescribed as functions of time Concentration on the right hand side of F=MA Basic concept dynamics Study of motion of a system as a consequence of applied forces and inertia forces Concentration on both sides of F=MA Displacement, velocity, acceleration and reaction force calculation of single or multiple degree of freedom systems ADAMS software demonstration Mainly modules： ADAMS/View ADAMS/Solver ADAMS/Postprocessor Simulation procedure Starting Adams/view ADAMS Interface Create model Rigid bodies Flexible bodies Point mass Ground Geometry building Geometry building--solid Geometry building--solid Geometry building feather operation Flexible body--Modal Neutral Files Geometry (locations of nodes and node connectivity) Nodal mass and inertia Mode shapes Generalized mass and stiffness for mode shapes How to create mnf ?
