This paper presents an analytical study on the dynamic stability of carbon nanotubes (CNTs) reinforced functionally graded composite beams when subjected to axial excitation loading. The are using a I-type CNTs reinforcement. section properties non-uniform assessed Halpin–Tsai model. analysis is performed by Bolotin’s method. Analytical expressions determining free vibration frequency, critical...

Sanyo has originally introduced 6HP two-cylinder rotary compressors for packaged airconditioners in I 985. The concept of two-cylinder rotary compressor has been recently applied to room airconditioners(RACs) for the purpose of reducing vibration and noise of the unit. However. RACs are demanded to decrease the noise by lowering levels of the compressor noise. SanYo has newly developed the quie...

In the article, mechanical and electromechanical starting characteristics of an asynchronous electric drive a two-piston ship compressor are investigated by numerical method. A distinctive feature operation reciprocating is that its load torque changes with certain frequency. The dependence on shaft piston angle rotation presented in form Fourier series. Moments inertia reduced to single system...

In previous work [1], our group implemented a tilted-mirror interferometric sensor that can measure rotation of a hybrid rotary-linear axis as part of a 5-DOF machine tool intended for fabricating centimeter-scale parts. Attached to the shaft of the hybrid axis is a tilted mirror rotary sensor, which uses two laser interferometers to measure the orientation of a tilted 3-inch diameter mirror at...

Based on the Alopex evolutionary optimization algorithm with constrained T-S model, this paper presents an intelligent fuzzy predictive controller to solve the control difficulties of industry process with multi-variables. The T-S model is firstly established for nonlinear multivariable systems and its sequence parameters of fuzzy rules are identified by local recursive least square method. The...
