On Stability Analysis of Bearing-Rotor System
The rotor system of the small power unit used in ball pen tip production machine, is discussed in detail. Meanwhile, nonlinear model of the rotor system is established and the related research method is introduced. Furthermore, the stability bifurcation of nonlinear periodic solution is obtained preliminarily. Characteristic comparisons between pseudo-periodic solution and chaotic one are put f...
متن کاملExperimental and Numerical Investigation of Two Different Traditional Hand-Baking Flatbread Bakery Units in Kashan, Iran
In present study, experimental measurements and mathematical modeling were employed to investigate the different parameters, such as temperature of different parts of oven, natural gas consumption, flue gases temperature and portion of different heat transfer mechanisms during baking, in two different traditional flatbread bakeries called Sangak (/sӑngӑk/) and Barbari (/bӑrbӑri/). In all studie...
متن کاملStability and vibration analysis of a complex flexible rotor bearing system
This paper presents the non-linear dynamic analysis of a flexible unbalanced rotor supported by ball bearings. The rolling element bearings are modeled as two-degree-of-freedom elements where the kinematics of the rolling elements are taken into account, as well as the internal clearance and the Hertz contact non-linearity. In order to calculate the periodic response of this non-linear system, ...
متن کاملinvestigation of gassing behavior, electric and dielectric properties of different insulating fluids.
ترانسفورماتورهای قدرت از اجزای اصلی شبکه تامین انرژی الکتریکی می باشند که عملکرد قابل اطمینان ترانسفورماتورها یکی از فاکتورهای مهم و تعیین کننده در تامین انرژی الکتریکی محسوب می شود. در نتیجه بررسی و مانیتور عملکرد ترانسفورماتورها در شبکه و همچنین عیب یابی این ترانسفورماتورها غیرقابل اجتناب و ضروری می باشد. به طور کلی عایق های مایع در صنعت فشار قوی کاربردهای متفاوتی دارند که مهمترین وظیفه آنها...
15 صفحه اولTheoretical, Numerical and Experimental Investigation on Formability of Al3105-St14 Two-Layer Sheet
Two-layer metallic sheets have wide applications in various industries due to their superlative characteristics. This paper presents analytical model to investigate the formability of two-layer sheets based on Marciniak and Kuckzinsky (M-K) method using Barlat and Lian non-quadratic yield criterion. FEM simulation is also performed to calculate the forming limits based on bifurcation theory. Fo...
