Influence of System Parameters on Main Rotor Response
The main purpose of this paper is concerned with the sensitivity analysis of main rotor dynamic response pertaining to variation of some relevant system parameters effectively supports the preliminary design of both articulated and hingeless helicopter rotor configurations. The methodology is laid out based on Galerkin solution of partial differential equation (PDE) of main rotor with flexible ...
متن کاملRotor Dynamic Response of a High-Speed Machine Tool Spindle
In high-speed machining, the maximum stable depth of cut at any spindle rotating frequency depends on the spindle-holder-tool dynamic stiffness as reflected at the tool’s free end. Because this dynamic stiffness can vary with rotating frequency, we have modeled the spindle dynamic response using a finite element-based rotordynamics approach. The spindle shaft is modeled using beam finite elemen...
متن کاملAeroelastic Modeling of a Nozzle Startup Transient
Lateral nozzle forces are known to cause severe structural damage to any new rocket engine in development during test. While three-dimensional, transient, turbulent, chemically reacting computational fluid dynamics methodology has been demonstrated to capture major side load physics with rigid nozzles, hot-fire tests often show nozzle structure deformation during major side load events, leading...
متن کاملResponse of lactating dairy ruminant to different profiles of dietary calcium soaps of fatty acids
Nutrition has a significant effect on reproduction and lactation in Ruminant. Supply of require nutrient of dairy cows and ewes in early lactation is the main challenges that will be considered, since in most cases the animals facing negative energy balance after calving and the beginning of the period of lactation. Negative energy balance may sometimes result in reduced livestock production an...
