Design of a Motorcycle Steering Damper for a Safer Ride [PDF]

Machines, 2020
Powered-two-wheelers (PTWs) are increasingly popular because of their lower cost compared to cars, and therefore the riders’ exposure risk is increasing. Due to their complex dynamics characterized by high non-linearity and inherent instability, PTWs are more difficult to control compared to four-wheeled vehicles. Wobble is a high-frequency instability

Method for Designing an Air Damper.

TRANSACTIONS OF THE JAPAN SOCIETY OF MECHANICAL ENGINEERS Series C, 1993
In this paper, we discuss a method for designing an air damper composed of a piston and a cylinder. When we design an air damper, we usually attend to obtain heavy damping. The amount of damping in the air damper, however, is limited by the compressibility of air. In an incompressible fluid damper such as the oil damper, the damping would increase with

Utilizing Low Yield Point Steel to Improve the Behavior of the I-Shaped Shear Links as Dampers

Buildings, 2023
Concentrically braced frame (CBF) systems are susceptible to buckling (which causes a decrease in energy absorption), although this system has considerable lateral stiffness and strength.

Constrained Layer Damper Modelling and Performance Evaluation for Eliminating Squeal Noise in Trams

Shock and Vibration, 2014
This paper presents the modelling and design of a constrained layer damper to eliminate squeal noise in a particular tram. Even though resilient wheels are installed in every bogie, squeal noise is generated at the frequency of 780–800 Hz due to the ...

Characteristics and Analysis of an Eddy Current Shock Absorber Damper Using Finite Element Analysis

Actuators, 2019
In the paper a model is developed for a proposed eddy current damper using finite element analysis. Several damper configurations are studied and its characteristics are analyzed. The steady state performance for the configurations is compared to reach a

Thermodynamic Behaviors of a Kind of Self-Decoupling Magnetorheological Damper

Shock and Vibration, 2015
A theoretical model of temperature change on a kind of self-decoupling magnetorheological (SDMR) damper was established based on conservation of energy, and the constraint equation for structural design parameters of the SDMR damper was improved to ...

A compact adjustable hydraulic damper with symmetric high load behavior enabled by selective laser melting

Journal of Low Frequency Noise, Vibration and Active Control, 2023
This publication addresses the development of a compact, adjustable hydraulic damper that meets the requirements for vibration testing. Dampers from the literature do not meet all the requirements, such as compact design, vibration resistance, high ...

Solutions for the Design and Increasing of Efficiency of Viscous Dampers [PDF]

The Open Construction and Building Technology Journal, 2016
In last decades many strategies for seismic vulnerability mitigation of structures have been studied and experimented; in particular energy dissipation by external devices assumes a great importance for the relative simplicity and efficacy. Among all possible approaches the use of fluid viscous dampers are very interesting, because of their velocity ...

Optimal Design Methodology of Maxwell–Coulomb Friction Damper

Vibration
The optimal design methodology for a Maxwell–Coulomb friction damper is proposed to minimize the resonant vibration of dynamic structures. The simple Coulomb friction damper has the problem of zero or little damping effect of the vibration of the spring ...
