Magnetorheological fluids set to revolutionise dynamic vehicle suspension systems

30.11.2005


Quarter suspension car model


Modeling and simulation of magnetorheological damper behavior under triangular excitation

Magnetorheological (MR) fluids are smart materials whose flow/viscosity properties can be modified by applying an electric field. These changes in viscosity occur within a fraction of a millisecond – far faster than conventional mechanical means – and can be used to effectively control vibrations in applications dealing with actuation, damping, robotics and mechatronics.

In this study published in AZojomo*, researchers Jorge A. Cortés R., Leopoldo S. Villarreal-González and Manuel Martínez M. from The Instituto Technologico de Estudios Superiores de Monterrey (ITESM) used dynamic simulations software to analyze the behavior and performance of systems consisting of rigid or flexible parts undergoing large displacement motions. A prime example of an application that meets these conditions is in vibration control in automotive suspension systems.



Initial experimentation was done using a prototype damper. The displacement of the damper was measured in stages while known compression forces are applied under the influence of different magnetic fields. This data was then used to develop simulations and models for damper response catering to different road surfaces.

The researchers found that reconfigurable suspension systems were technologically feasible using magnetorheological fluids. Future work is required to develop the software algorithms to control the damping action. The resultant mechatronic system would respond not only to the road conditions but also comfort levels required by the vehicle occupants.

Im Focus: BAM@Hannover Messe: innovative 3D printing method for space flight

At the Hannover Messe 2018, the Bundesanstalt für Materialforschung und-prüfung (BAM) will show how, in the future, astronauts could produce their own tools or spare parts in zero gravity using 3D printing. This will reduce, weight and transport costs for space missions. Visitors can experience the innovative additive manufacturing process live at the fair.

Powder-based additive manufacturing in zero gravity is the name of the project in which a component is produced by applying metallic powder layers and then...

Im Focus: Molecules Brilliantly Illuminated

Physicists at the Laboratory for Attosecond Physics, which is jointly run by Ludwig-Maximilians-Universität and the Max Planck Institute of Quantum Optics, have developed a high-power laser system that generates ultrashort pulses of light covering a large share of the mid-infrared spectrum. The researchers envisage a wide range of applications for the technology – in the early diagnosis of cancer, for instance.

Molecules are the building blocks of life. Like all other organisms, we are made of them. They control our biorhythm, and they can also reflect our state of...

Im Focus: Spider silk key to new bone-fixing composite

University of Connecticut researchers have created a biodegradable composite made of silk fibers that can be used to repair broken load-bearing bones without the complications sometimes presented by other materials.

Repairing major load-bearing bones such as those in the leg can be a long and uncomfortable process.
