Vibration Characteristics Analysis of O-Shaped Damping Ring to Balance Damping Gear Transmission System for Three-Cylinder Engine

Damping Models for Structural Vibration

This dissertation reports a systematic study on analysis and identification of multiple parameter damped mechanical systems. The attention is focused on viscously and non-viscously damped multiple degree-offreedom linear vibrating systems. The non-viscous damping model is such that the damping forces depend on the past history of motion via convolution integrals over some kernel functions. The ...

The Analysis of Vibration Characteristics and Motion Stability of the Tracked Ambulance Nonlinear Damping System

Considering the impact of the nonlinear stiffness, a 2 DOF dynamic nonlinear vibration model with cubic terms was established according to the structural feature and nonlinear behavior of the tracked ambulance. In the case of primary resonance and 1: 1 internal resonance, multiple scale method was used to obtain a first-order approximate solution for this model. Taking the parameters of the tra...

Active Vibration Control of Gear Transmission System

In this paper, an active control structure used piezoelectric stack actuator is built to suppress vibration due to internal incentive in gear transmission. Because the gear system is timevariant and unknown, an offline modeling technique is unable to tracking the changes in the secondary path, an adaptive filter algorithm used online secondary path modeling method is proposed to the active vibr...

Dynamic analysis of three-cylinder engine with balancing shaft

Three-cylinder linear engines are designed to minimize, reduce fuel consumption and pollution. The disadvantages of this type of engine, heavy vibration inherent in them. this study aims to balance Three-cylinder linear engines with a balancing shaft. First, the dynamic analysis of these types of engines identifies unbalanced sources. The results of the dynamic analysis showed that the inertial...
