RISAutomated Analysis of Constrained Systems of Rigid and Flexible Bodies
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: This paper is concerned with modeling inertia properties of flexible components that undergo large angular rotations. Consistent, lumped and hybrid mass techniques are presented in detail and ...
Dynamics of Flexible Bodies Using Generalized Newton-Euler Equations
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: A force acting on a rigid body produces a linear acceleration for the whole body together with an angular acceleration about its center of mass. This result is in fact Newton-Euler equations ...
Finite Element Incremental Approach and Exact Rigid Body Inertia
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: In the dynamics of multibody systems that consist of interconnected rigid and deformable bodies, it is desirable to have a formulation that preserves the exactness of the rigid body inertia. ...
Nonlinear Finite Element Formulation for the Large Displacement Analysis of Plates
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: In this investigation a nonlinear total Lagrangian finite element formulation is developed for the dynamic analysis of plates that undergo large rigid body displacements. In this formulation shape ...
A Recursive Formulation for the Dynamic Analysis of Open Loop Deformable Multibody Systems
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: In this paper, a recursive formulation for the spatial kinematic and dynamic analysis of open chain mechanical systems containing interconnected deformable bodies, each of which may undergo large ...
Effects of Shear Deformation and Rotary Inertia on the Nonlinear Dynamics of Rotating Curved Beams
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: In this investigation a method for the dynamic analysis of initially curved Timoshenko beams that undergo finite rotations is presented. The combined effect of rotary inertia, shear deformation, ...
On the Use of the Momentum Balance in the Impact Analysis of Constrained Elastic Systems
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: In elastic systems, impulsive forces that act at a point on a deformable body produce stress waves that travel with finite speeds. This paper examines, both theoretically and numerically, the ...
Dynamics of Multibody Tracked Vehicles Using Experimentally Identified Modal Parameters
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: The mode shapes, frequencies, and modal mass and stiffness coefficients of multibody systems such as tracked vehicles can be determined using experimental identification techniques. In multibody ...
Geometrically Nonlinear Formulations of Beams in Flexible Multibody Dynamics
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: In this paper, the equations of motion of flexible multibody systems are derived using a nonlinear formulation which retains the second-order terms in the strain-displacement relationship. The ...
Spatial Dynamics of Deformable Multibody Systems With Variable Kinematic Structure: Part 2—Velocity Transformation
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: In Part 1 of these two companion papers, the spatial system kinematic and dynamic equations are developed using the Cartesian and elastic coordinates in order to maintain the generality of the ...
