Dynamic characteristic analysis of crank connecting rod mechanism in star-type air compressor

open access: yesZhongguo Jianchuan Yanjiu, 2018
[Objectives] Compared with other types of air compressor, reciprocating compressors can obtain compressed air with a higher pressure, exerting more stress on the crank connecting rod mechanism.

Solitary waves on a ferrofluid jet [PDF]

open access: yes, 2014
The propagation of axisymmetric solitary waves on the surface of an otherwise cylindrical ferrofluid jet subjected to a magnetic field is investigated. An azimuthal magnetic field is generated by an electric current flowing along a stationary metal rod ...

Cartesian space track planning for welding robot with inverse solution multi-objective optimization

open access: yesMeasurement + Control, 2022
Aiming at the problem that the traditional inverse solution optimization method is not comprehensive and does not consider the robot structure and actual working conditions, an inverse solution multi-objective optimization method is proposed. This method

Cyclic nucleotide-gated channels: structural basis of ligand efficacy and allosteric modulation [PDF]

open access: yes, 1997
Most working proteins, including metabolic enzymes, transcription regulators, and membrane receptors, transporters, and ion channels, share the property of allosteric coupling. The term 'allosteric' means that these proteins mediate indirect interactions

Optimized Design of Fixture Mechanism for Cotton Bundle Fiber

open access: yesActuators, 2023
The linkage mechanism of a cotton bundle fiber strength tester will have an unstable clamping force when clamping fiber bundle samples with uneven thickness, resulting in slippage or damage to the fibers increasing the pectin residue, leading to ...

Kinematic and Dynamic Simulation Analysis of Modified Conventional Beam Pumping Unit

open access: yesEnergies, 2022
The large net torque fluctuations in the reducer output shafts of conventional beam pumping units and the existence of negative torque are the decisive factors that lead to their low efficiency and high energy consumption. This study developed a positive

Research on the Compound Crank-link Mechanism with Precise Sine Output Characteristics

open access: yesJixie chuandong, 2023
Aiming at the transmission characteristics of the second harmonic of a single crank connecting rod mechanism, a composite crank connecting rod mechanism with output precise sinusoidal velocity-time characteristics is innovatively proposed.

Shape of an elastica under growth restricted by friction [PDF]

open access: yes, 2018
We investigate the quasi-static growth of elastic fibers in the presence of dry or viscous friction. An unusual form of destabilization beyond a critical length is described. In order to characterize this phenomenon, a new definition of stability against
