Researchers in Hong Kong have developed a linear switched reluctance actuator for automobile active suspension system. This system can significantly improve suspension performance and collect suspension energy.
This invention by researchers at The Hong Kong Polytechnic University (HKPolyU) is a linear switched reluctance actuator for automobile active suspension system. It is an electromagnetic design. The actuator’s vertical position (i.e. the vehicles’ horizontal level) can be adjusted easily.
The response time of the suspension system is much shorter than conventional ones which consist of hydraulic and mechanical parts. It generates control forces to quickly absorb road shocks, suppress vibration and ameliorate both riding safety and comfort.
More importantly, the system can recycle the energy generated from the suspension to charge the vehicle batteries. Taking the electric vehicle “mycar” as an example, this system can save up to about 5% of the energy consumption when riding on countryside
Special Features and Advantages
• Enables active electromagnetic suspension in vehicles, including electric vehicles and petrol cars
• Simple and robust configuration
• Recycles the suspension energy of vehicles (50-300W of electricity could be re-generated during lab test)
• Fast dynamic performance
• Direct drive with high efficiency
• Intelligent force control
• Optimizes the design of linear switched reluctance actuators
• Active suspension system for vehicles
• Vibration energy recycling system for vehicles
• Power seats with active suspension in vehicles
• Other cases which need active suspension, such as aircrafts and ships

Researchers at the University of New Hampshire have captured a difficult-to-view singular event involving "magnetic reconnection"--the process by which sparse particles and energy around Earth collide producing a quick but mighty explosion--in the Earth's magnetotail, the magnetic environment that trails behind the planet.
Magnetic reconnection has remained a bit of a mystery to scientists. They know it exists and have documented the effects that the energy explosions can...
Biochips have been developed at TU Wien (Vienna), on which tissue can be produced and examined. This allows supplying the tissue with different substances in a very controlled way.
Cultivating human cells in the Petri dish is not a big challenge today. Producing artificial tissue, however, permeated by fine blood vessels, is a much more...
Faster and secure data communication: This is the goal of a new joint project involving physicists from the University of Würzburg. The German Federal Ministry of Education and Research funds the project with 14.8 million euro.
In our digital world data security and secure communication are becoming more and more important. Quantum communication is a promising approach to achieve...
On Saturday, 10 November 2018, the research icebreaker Polarstern will leave its homeport of Bremerhaven, bound for Cape Town, South Africa.
When choosing materials to make something, trade-offs need to be made between a host of properties, such as thickness, stiffness and weight. Depending on the application in question, finding just the right balance is the difference between success and failure
Now, a team of Penn Engineers has demonstrated a new material they call "nanocardboard," an ultrathin equivalent of corrugated paper cardboard. A square...
