Dynamic analysis of the variable stiffness support rotor system with elastic rings
نویسندگان
چکیده
Elastic rings are common rotor supporting structure, which have been widely used in aeroengine support system. However, large inertia force and gyroscopic moment may occur during the operation of aeroengine, lead to contact between elastic ring bearing pedestal, then introduce variable stiffness into In this paper, a mathematical model is proposed subsequently verified by comparison with simulation analysis experimental results. Based on model, an ring-supported developed coupling kinetic equations deformation combined support. Then, spectrum cascades analyze dynamic characteristics addition, influences critical speed system also examined. Finally, some results experiments test bench rotor.

The Effect of Damping and Stiffness of Bearing on the Natural Frequencies of Rotor-bearing System
In this paper, the effectiveness of stiffness and damping of bearing is investigated on the natural frequencies of the rotor-bearing system. The rotor-bearing system consists of a shaft, two bearings and a disk between two bearings. Parallel spring-damper in horizental and vertical directions is considered for modeling the stiffness and damping of bearings. The gyroscopic effect is also conside...
متن کاملStudy of dynamic crack branching using intrinsic cohesive surfaces with variable initial elastic stiffness
As observed by Needleman and co-workers [1], it is still not clear to what extent the initially elastic cohesive surfaces are more appropriate than the initially rigid cohesive surfaces for a given application. In this work, an analysis where the initially elastic model is approached asymptotically to the initially rigid is proposed. The purpose of this analysis is to gain more insight into the...
متن کاملAnalysis of System Dynamic Influences in Robotic Actuators with Variable Stiffness
In this paper the system dynamic influences in actuators with variable stiffness as contemporary used in robotics for safety and efficiency reasons are investigated. Therefore, different configurations of serial and parallel elasticities are modeled by dynamic equations and linearized transfer functions. The latter ones are used to identify the characteristic behavior of the different systems a...

Dynamic Analysis of an axially moving cable with time dependent tension and velocity isstudied in this paper. Tension force and the moving speed are assumed to be harmonic.It is found that there exists a specific value of speed in which natural frequency of the system approacheszero. This specific speed for such a critical condition is called critical speed and it will be proved thatincreasing ...
