Kinetics Modeling for Slider-Crank Mechanism [PDF]
Proceedings of the Third International Conference on Control, Automation and Systems Engineering, 2013 This paper proposes a procedure to extract the kinetic model from the geometric model of a fixture to reduce the modeling time and effort. Since most of the fixtures in industry follow the same kinetic mechanism, the so-called a slider-crank mechanism; this is a four-axis system of three revolute and one prismatic joint. The prismatic axis of a fixture

Effect of the Rotor crank system on cycling performance [PDF]
, 2009 The aim of this study was to evaluate the impact of a novel crank system on laboratory time-trial cycling performance. The Rotor system makes each pedal independent from the other so that the cranks are no longer fixed at 180°.

Study on the Model of Slider-crank Mechanism with Clearance based on Parameter Identification Method
Jixie chuandong, 2017 In order to solve the problem of the clearance on the slider-crank mechanism and improve the position precision of the slider-crank mechanism. Starting from the simple mechanism of slider-crank mechanism,the simplified model is established.

Dynamic Analysis on Crank-Slider Mechanism of Reciprocating Pump
, 2011 The crank-slider mechanism is the key component in reciprocating pumps. With the increase of the rotational speed of the crank-slider mechanism, the vibration and working noise of reciprocating pumps increase. Based on the multi-body dynamics theory, the

Advanced Materials, EarlyView.Heterostructure photodiode devices of p‐type WSe2 with n‐type NiPS3 constructs spectrally protected spin‐polarized photocurrents. The energy of the excitation photon serves as an independent control parameter for spin‐selective photocurrent generation. ABSTRACT Efficient generation and control of spin‐polarized currents in semiconductors remain central

Charge Storage and Dark Photocatalysis in Multivariate Ti‐Based Metal‐Organic Frameworks
Advanced Materials, EarlyView.The mixed‐linker series of the titanium‐based metal–organic framework COK‐47 enables systematic tuning of photoresponsiveness and (dark) photocatalytic activity, deepening our understanding of structure‐property‐function relationships. Tailored metal‐to‐ligand charge transfer between the secondary building units (metal‐oxo layers and organic linkers ...
