Ales Tech active suspension system - a preliminary concept

Ales Tech active suspension system - a preliminary concept

Hyperloop is our first challenge. High speed levitation systems allow low friction, but create extremely high forces and vibrations at a structural level.

We want to make the Hyperloop suitable for humans. For this reason our requirements are comfort, in terms of sound and human body vibration, and a correct dynamical behavior of the pod, in order to maintain the pod stability and ensure a correct behavior of the bearing. The challenge is to preserve this condition when the speed increases and goes beyond the sound barrier.

ALES has been already chosen as the official suspension system by several teams that are competing in the finals of the SpaceX Hyperloop Pod Competition.

A new suspension technology

ALES, Ales Tech’s Active Suspension System, is specifically designed to meet the high standards of the Hyperloop and is suitable to be adapted to other high-speed transportation systems. By applying innovative technologies at the crossroads between mechanical, electrical and control engineering, we created a versatile system that maximizes safety, performance and comfort.

With adaptive kinematicsactive control and modularity, ALES goes beyond the idea of passive suspension, in environments where no compromise in terms of cost and performances can be tolerated. ALES is currently patent pending internationally. 


KEY FEATURES

ACTIVE CONTROL

The active control technology consists of a smart element, an electromagnetic actuator controlled with an active control strategy. 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. The Hyperloop can go faster and vibrations are no more an issue.

ADAPTIVE KINEMATICS

Ordinary suspensions have only a principal movement, that often is the vertical movement, in order to follow vertical 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 are required.

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

MODULARITY

Ales Tech’s 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


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.
