Active Suspension Systems / 主動懸掛系統

High-speed trains are essential to reduce travelling distances between two points. However, higher speeds have their downsides, namely increased forces and accelerations, which have a negative effect on ride comfort. As conventional passive suspension systems fall short to address these needs, active suspension technologies can be implemented to maintain or improve ride comfort at increased vehicle speeds or under unfavorable track conditions.

An active, computer-monitored, suspension system relies heavily on accurate readings provided by high-tech accelerometers, which is where our MEMS accelerometers truly shine.

Accurate vibration sensing – the key to enhanced ride comfort

Colibrys MEMS accelerometers provide precise and stable vibration measurements even under harsh conditions, feeding this information into the control system for the active suspension and allowing it to adjust accordingly so that passengers benefit from an enhanced ride comfort. Using our sensors, the vibrations of the car body can be reduced by 66%.

Moreover, a MEMS accelerometer also increases the lifespan of the suspension system itself, as it provides valuable data that allow for the planning of maintenance and repair work, saving essential maintenance costs in the long run.

 

The MEMS revolution

There are many sensing technologies (capacitive, piezoelectric, piezoresistive, etc.) competing to provide the best solution for today’s active suspension applications, but none offer the same level of performance in terms of long-term stability, temperature stability and precision as MEMS capacitive products, which are not only qualified for safety critical applications, but are also designed to operate in harsh environments.

 

Measuring vibration

Our accelerometers are extra-small high-end products that combine together large bandwidth, robustness and low power designs, featuring an excellent bias stability, which serves as a guarantee for reliability. Colibrys provides a MEMS capacitive sensor which features a bulk micro-machined silicon element, a low-power ASIC for signal conditioning and a temperature sensor.

 

Advantages of our vibration sensors

Colibrys vibration sensing MEMS accelerometers are defined by low power consumption, high calibration, robustness and stability, with the electronic configuration providing a solid power on reset and ensuring a full protection against brown-outs. They come in extra-small LCC20 packaging (8.9mm x 8.9mm) and are characterized by an outstanding large and flat frequency response from DC 0 Hz to 1500 Hz ±5% (min) and a full scale range of ±2g to ±200g.

The new vibration sensor optimized architecture offers exceptional temperature stability with So ± 0.2 mg/°C (min/max) and Sz 120 ppm/°C (typ) from -55°C to +125°C. It also embeds an overload detection and recovery after shocks. The non-linearity becomes almost nonexistent with 0.1 % of full scale, under vibrations (typ). It offers the lowest noise of 7 μg/√Hz in band with the 2g range (typ). It can measure from ±2g to ±200g.

 

Colibrys – the stable ride towards innovation

Colibrys produces MEMS capacitive accelerometers renowned for high reliability under harsh conditions, devices that have been successfully tested and implemented in safety critical railway applications.

One of our most resonating achievements was the Colibrys sensors to be successfully qualified for the latest generation of German ICE high speed trains. The Velaro D train is the fourth generation of interoperable high-speed trains made by Siemens using distributed traction and the first integrating innovative bogie monitoring systems.

 

Colibrys accelerometers for active suspension systems

  • The new Colibrys VS1000 – a new reference for low to medium frequency MEMS sensing (DC 0 Hz to 1500 Hz) – offers the best performance stability with shock resistance, as well as the lowest non-linearity and noise in the marketplace. Each product is fully tested and qualified to the highest Colibrys standards. It embeds a self-test function for your confidence at all time.
  • The legacy Colibrys VS9000 – the trusted MEMS for the most demanding applications involving vibration sensing since 2008 – it offers large frequency response and performance stability, as well as low power consumption.
