Harmonic Transfer Function Based Damage Identification of Breathing Cracked Jeffcott Rotor

Autor: Jie Zhao, Hans DeSmidt, Meng Peng

Publikováno v: Shock and Vibration, Vol 2016 (2016)

This paper proposes a vibration-based damage identification method based on 6-dof Jeffcott rotor system, which is based on harmonic balance and Newton-Raphson methods. First, the equations of motion are derived by using energy method and Lagrange pri

System and Component Level Design Procedure for High Reduction Ratio Pericyclic Drive

Autor: Tanmay D. Mathur, Edward C. Smith, Hans DeSmidt, Robert C. Bill

Publikováno v: Journal of the American Helicopter Society. 67:28-39

The focus of this work is to integrate component-level design analyses developed for different machine elements of a twin pericyclic drive into a comprehensive design decisions framework. The integrated system loads, bearing loads, and tooth contact

Dynamic Load Analysis of Motion Converter Ball Bearings in a Pericyclic Transmission

Autor: Nick J. Weinzapfel, Nathan W. Bolander, Tanmay D. Mathur, Hans DeSmidt, Edward C. Smith

Publikováno v: Journal of the American Helicopter Society.

Performance of ball bearings in the motion converter subassembly of an internally driven, single-speed, torque-split, twin configuration pericyclic transmission prototype is evaluated to extend the analytical knowledge base on this innovative transmi

Nonlinear Coupled Torsion/Lateral Vibration and Sommerfeld Behavior in a Double U-Joint Driveshaft

Autor: Hans DeSmidt, Wei Yao

Publikováno v: Journal of Vibration and Acoustics. 143

Many driveline systems are designed to accommodate angular misalignment by the use of flexible couplings or Universal Joints (U-Joints) which link individual shaft segments. The Sommerfeld effect is a nonlinear phenomenon observed in some rotor syste

Non-linear behaviors of off-centered Planar eccentric rotor/autobalancer system mounted on asymmetric and rotational flexible foundation

Autor: DaeYi Jung, Hans DeSmidt

Publikováno v: Journal of Sound and Vibration. 429:265-286

This research explores the non-linear and automatic balancing behaviors of passive automatic balancer device(ABD) system for planar eccentric rotor longitudinally off-centered from the mass center of flexible foundation structure that can move horizo

A new hybrid observer based rotor imbalance vibration control via passive autobalancer and active bearing actuation

Autor: Hans DeSmidt, DaeYi Jung

Publikováno v: Journal of Sound and Vibration. 415:1-24

Many researchers have explored the use of active bearings, such as non-contact Active Magnetic Bearings (AMB), to control imbalance vibration in rotor systems. Meanwhile, the advantages of a passive Auto-balancer device (ABD) eliminating the imbalanc

Rotor Balancing Via an Enhanced Automatic Dynamic Balancer With Inductively Coupled Shunt Circuit

Autor: Hans DeSmidt, Xiaowen Su

Publikováno v: Journal of Vibration and Acoustics. 141

Despite the elegant nature of the automatic balancing principle for passive imbalance vibration control, the co-existence of undesired whirling limit-cycles is a major impediment to the more widespread application of automatic dynamic balancing devic

Parametric Instability of Planetary Gear Transmission Mounted on Discrete Support Struts With Minimum Ring Gear Rim Thickness Design

Autor: Hans DeSmidt, Peng Guan

Publikováno v: Volume 4B: Dynamics, Vibration, and Control.

This research explores parametric instabilities of the PGT driveline system and a stability-based method for ring gear rim thickness design. Parametric excitation of a planetary gear transmission (PGT) driveline system arises from two sources: 1) gea
