1 ADAMS ADAMS Virtual Prototyping Technology Virtual Prototyping Technology ----Basic Training ----Basic Training 2 Contents Contents ? Basic Concept ? Using Software ? Application Examples 3 Basic Concept Basic Concept ? ADAMS : Automatic Dynamic Analysis Mechanical System ? Research Object : mechanical system ? Research Area : kinematics and dynamics 4 Basic concept kinematics 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 ? Forces cannot affect motion ? Forces calculated as a consequence of motion ? Displacement, velocity, acceleration and reaction force solution is algebraic in nature ? No need to solve differential equations Consequence Definition 5 Basic concept dynamics 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 ? Forces affect accelerations ? Accelerations are integrated to velocities ? Velocities are iterated to give displacements ? 2nd order differential equations are to be solved Consequence Definition 6 ADAMS software demonstration ADAMS software demonstration Mainly modules : ?
