Control of the Active Suspension for In-Wheel Motor

open access: yesJournal of Advanced Mechanical Design, Systems, and Manufacturing, 2013
This study raises a new electric wheel with active control of suspension for in-wheel motor. Proceeding from the reality, we made a simulation analysis on these four models: a sample car with no motor, a motor with fixed joint, and active/inactive ...

Theory of Active Suspension Design

open access: yesJournal of Robotics and Mechatronics, 1995
Active suspension design has been developed as the application of optimal control theory. However, optimal control theory is only suitable for the design of regulator, where transient responses starting from any initial state are required to converge to zero.

Fibrin Suspension Assay for Fibrinolytic Activity [PDF]

open access: yesBlood, 1964
Abstract A new method has been described for measuring fibrinolytic activity. The method is based on the change in turbidity resulting from the dissolution of suspended particles of fibrin under the influence of fibrinolytic agents. Because the technic exposes a vast surface area of substrate, measurable changes occur rapidly.

Object transport by a confined active suspension

open access: yesJournal of Fluid Mechanics, 2023
Numerical simulations in two space dimensions are used to examine the dynamics, transport and equilibrium behaviours of a neutrally buoyant circular object immersed in an active suspension within a larger circular container. The continuum model of Gao et al. (Phys. Rev. Fluids, vol. 2, issue 9, 2017, 093302) represents the suspension of non-interacting,

Multimode Coordination Control of a Hybrid Active Suspension

open access: yesShock and Vibration, 2018
In order to effectively realize the damping control and regenerative energy recovery of vehicle suspension, a new kind of hybrid active suspension structure with the ball screw actuator and magnetorheological (MR) damper is put forward.
