Closed-Form Transient Response of Distributed Damped Systems, Part I: Modal Analysis and Green’s Function Formula
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: An analytical method is developed for closed-form estimation of the transient response of complex distributed parameter systems that are nonproportionally damped, and subject to arbitrary external, ...
Closed-Form Transient Response of Distributed Damped Systems, Part II: Energy Formulation for Constrained and Combined Systems
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: The transient response analysis presented in Part I is generalized for distributed damped systems which are viscoelastically constrained or combined with lumped parameter systems. An energy ...
On Singularity of Rigid-Body Dynamics Using Quaternion-Based Models
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: It is well known that use of quaternions in dynamic modeling of rigid bodies can avoid the singularity due to Euler rotations. This paper shows that the dynamic response of a rigid body ...
Analysis of Ring-Stiffened Cylindrical Shells
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: A new analytical and numerical method is presented for modeling and analysis of cylindrical shells stiffened by circumferential rings. This method treats the shell and ring stiffeners as individual ...
A Thermal Stability Criterion for Heat Conduction in Multilayer Composite Solids
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: Excessive heat generation within a body can cause unbounded temperature or thermal instability. In this work, a new stability test is established for heat conduction in one-dimensional multilayer ...
Modeling and Design of a Piezoelectric Forceps Actuator for Meso∕Micro Grasping
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: Meso∕micro grasping of tiny soft objects such as biological tissues, which ranges from hundreds to thousands of micro-millimeters in dimension, plays a significant role in the fields of tele-surgery, ...
On Transfer Function Zeros of General Colocated Control Systems With Mechanical Flexibilities
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: In our previous work, it was shown that for simple control systems with mechanical flexibilities such as spring-mass systems or uniform cross-section linear elastic beams, the complex conjugate ...
