A bifurcation study to guide the design of a landing gear with a combined uplock/downlock mechanism [PDF]

open access: yes, 2014
This paper discusses the insights that a bifurcation analysis can provide when designing mechanisms. A model, in the form of a set of coupled steady-state equations, can be derived to describe the mechanism.

Determination of Energy Losses of the Crank Press Mechanism

open access: yesMachines
This paper focuses on determining the friction energy loss in the mechanism of a mechanical crank press. After defining the crank press mechanism and how it works, we describe the energy balance of a technological operation—forming.

Scavenge flow analysis of opposed-piston two-stroke engine based on dynamic characteristics

open access: yesAdvances in Mechanical Engineering, 2015
Opposed-piston two-stroke engine has been proposed by Beijing Institute of Technology to improve power density and complete machine balance relative to conventional engines. In order to study opposed-piston two-stroke engine scavenging flow, a scavenging

A Lie group variational integrator in a closed-loop vector space without a multiplier [PDF]

open access: yesMechanical Sciences
As a non-tree multi-body system, the dynamics model of four-bar mechanism is a differential algebraic equation. The constraints breach problem leads to many problems for computation accuracy and efficiency.

Enhanced vibrational energy harvesting using non-linear stochastic resonance [PDF]

open access: yes, 2008
Stochastic resonance has seen wide application in the physical sciences as a tool to understand weak signal amplification by noise. However, this apparently counter- intuitive phenomenon does not appear to have been exploited as a tool to enhance ...
