A new suspension technology

ALES, Ales Tech’s Active Suspension System, has been specifically designed to meet the high standards of the Hyperloop, while it is suitable to be adapted to other high-speed transportation systems. By introducing innovative mechatronics technologies, we created a versatile system that maximizes safety, performance and comfort.

With adaptive kinematicsactive control and modularity, ALES goes beyond the traditional idea of passive suspension, in environments where no compromise in terms of cost and performance can be tolerated.

Hyperloop has been our first application for the ALES technology. In this domain, high speed levitation systems can be introduced in order to reduce the friction, but at the same time create extremely high forces and vibrations at a structural level.

We wanted to make the Hyperloop suitable for humans in terms of comfort and safety. For this reason we focused on both vehicle's vibration and on the dynamical behavior of the pod, in order to keep the pod stability and ensure a correct behavior of the bearing at speeds that can reach 700 mph. The challenge is to preserve this condition when the speed increases and goes beyond the sound barrier.

ALES has been chosen as the official suspension system by several teams that participated to the first SpaceX Hyperloop Pod Competition and is patent pending internationally.

KEY FEATURES

ACTIVE CONTROL

The active control technology consists of a smart element, an electromagnetic actuator controlled by a computerized control unit. The controlled actuator is able to change its force value at very high speeds, reducing vibration and improving pod stability. The control system predicts surface imperfections and adapts the system.

Ales Tech’s active control allows great performance improvements compared to traditional suspension systems. Thanks to this feature, the Hyperloop can go faster and vibrations do not represent an issue.

ADAPTIVE KINEMATICS

Ordinary suspensions have only a main movement, that is often vertical, in order to follow the changes of the road’s profile.

Hyperloop levitation systems impose strong requirements in terms of the ski’s alignment and positioning. For this reason multiple kinematics movements can be introduced.

Our solution features adaptive kinematics and allows the skis to be constantly aligned and responsive, accommodating the smallest track’s imperfections.

MODULARITY

ALES design is characterized by interchangeable modular subassemblies. This approach leads to strong advantages in terms of flexibility and reliability of the overall system.

FAIL-SAFE DESIGN

The active element is integrated in the suspension through a parallel design of passive components that support the static forces. If something goes wrong with the active control, there is always a passive backup.


Ales Tech's Active Suspension System has been extensively tested during the prototyping phase of the SpaceX Hyperloop Pod Competition at SpaceX facilities in Hawthorne, CA.

Thanks to its versatility, the system can be adapted to other typologies of vehicles, from cars to high­-speed trains, roller­-coasters, and potentially to any high-­frequency vibrating device, such as industrial machines.
