A new process damping model for chatter vibration
(2011)
This paper presents a new analytical process damping model (PDM) and calculation of Process Damping Ratios (PDR) for chatter vibration for low cutting speeds in turning operations. In this study a two degree of freedom ...
Application of Phase Change Materials to Pre-Heating of Evaporator and Pressure Regulator of a Gaseous Sequential Injection System
(2011-07-23)
The vehicle engines having gaseous sequential injection systems of liquefied petroleum gas (LPG) are operated on gasoline until the engine coolant reaches the required temperature because the heat of the engine coolant ...
Optimization of tool geometry parameters for turning operations based on the response surface methodology
(2011)
This investigation focuses on the influence of tool geometry on the surface finish obtained in turning of AISI 1040 steel. In order to find out the effect of tool geometry parameters on the surface roughness during ...
A simple approach to analyze process damping in chatter vibration
(2014)
This paper investigates how changes in chatter amplitude and frequency depend on process damping effect in dynamic turning process. For this purpose, the two degrees of freedom (TDOF) cutting system was modeled, and for ...
Linear analysis of chatter vibration and stability for orthogonal cutting in turning
(2011)
The productivity of high speed milling operations is limited by the onset of self-excited vibrations known as chatter. Unless avoided, chatter vibrations may cause large dynamic loads damaging the machine spindle, cutting ...
A Review on Thermal Energy Storage Systems With Phase Change Materials in Vehicles
(2012)
Thermal energy storage (TES) with phase change materials (PCMs) has been one of the main topics in research lately. Although the information is quantitatively enormous, there have not been more studies on its applications ...
A Comparative Analysis of Alternative Energy Sources Used in Automobiles
(2014-06-18)
Due to the rapid decline of oil reserves and the environmental regulations that lower the limit values of exhaust emissions released into the atmosphere the car makers and the scientific communities have been accelerating ...
Decomposition of Process Damping Ratios and Verification of Process Damping Model for Chatter Vibration
(2012)
In the previous study, by the same authors, titled ‘‘A new process damping model (PDM) for chatter vibration (Measurement, 44 (8) (2011) 1342–1348)’’, a new approach has been presented for obtaining process damping ratios ...
