RISHamel Paradox and Rosenberg Conjecture in Analytical Dynamics
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: Hamel proposed a seemingly intuitive, simple, straightforward, but incorrect, method of formulating the constrained equation of motion. The method has to do with the direct embedding of the constraint into the kinetic ...
Stress Shifting Effect of Hydrogen Mixed Natural Gas Pipe Under Seismic Wave
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: Hydrogen energy is a kind of clean secondary energy sources. Mixed hydrogen natural gas transportation technology is a new scheme of hydrogen transportation. Using natural gas pipe to transport hydrogen is expected to ...
Udwadia Kalaba Approach for Parallel Manipulator Dynamics
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: A novel UdwadiaKalaba approach for parallel manipulator dynamics analysis is presented. The approach segments a parallel manipulator system into several legsubsystems and the platform subsystem, which are connected by ...
Mathematical Insights Into Linear Mode Localization in Nearly Cyclic Symmetric Rotors With Mistune
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: In this paper, we develop a mathematical analysis to gain insights of mode localization often encountered in nearly cyclic symmetric rotors that contain slight mistune. First, we conduct a Fourier analysis in the spatial ...
Effects of Bearings and Housing on Mode Localization of a Nearly Cyclic Symmetric System
