RISEstimation of Road Friction Coefficient Based on the Brush Model
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: Road friction coefficients are highly effective for advanced vehicle control technologies, although the estimation at four individual tires has not been practically used for ordinary vehicles. ...
H2 Optimization of the Three-Element Type Dynamic Vibration Absorbers
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: The dynamic vibration absorber (DVA) is a passive vibration control device which is attached to a vibrating body (called a primary system) subjected to exciting force or motion. In this paper, ...
Closed-Form Exact Solution to H∞ Optimization of Dynamic Vibration Absorbers (Application to Different Transfer Functions and Damping Systems)
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: H∞ optimization of the dynamic vibration absorbers is a classical optimization problem, and has been already solved more than 50 years ago. It is a well-known solution, but we know this ...
Analytical and Experimental Evaluation of an Air Damped Dynamic Vibration Absorber: Design Optimizations of the Three-Element Type Model
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: In this paper, we propose a dynamic vibration absorber (DVA) with an air damper consisting of a piston and a cylinder. First, it will be shown that the air damper can conveniently be ...
Closed-Form Solutions to the Exact Optimizations of Dynamic Vibration Absorbers (Minimizations of the Maximum Amplitude Magnification Factors)
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: A typical design problem for which the fixed-points method was originally developed is that of minimizing the maximum amplitude magnification factor of a primary system by using a dynamic ...
Analytical Solutions to H∞ and H2 Optimization of Dynamic Vibration Absorbers Attached to Damped Linear Systems
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: H∞ and H2 optimization problems of the Voigt type dynamic vibration absorber (DVA) are classical optimization problems, which have been already solved for a special case when the primary system ...
A New Control Strategy to Reduce Steering Torque Without Perceptible Vibration for Vehicles Equipped With Electric Power Steering
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: This paper proposes a new electric power steering control strategy, which significantly reduces the effort needed to change the steering direction of stationary vehicles. Previous attempts to ...
