Uncompensated lateral acceleration in curves

For high-speed trains, curves present a particular challenge: uncompensated lateral acceleration can affect passenger comfort and limit operating speeds. Advanced tilt technology helps overcome this – but it depends on exceptionally precise acceleration data.

This is where JAE JA-80GA and JA-40GA quartz-based accelerometers come into play. Their servo-balanced quartz technology delivers outstanding precision, stability and resolution, making them ideally suited for demanding rail control and measurement applications.

The JA-80GA accelerometer, for example, offers a measurement range of ±30 g, resolution below 1 µg and excellent long-term stability. It can support precise control of train tilting, allowing vehicles to negotiate curves faster while maintaining passenger comfort.

The benefits extend beyond speed: optimized curve negotiation can increase transport capacity, reduce braking, minimize wear and tear, improve energy efficiency and enhance passenger satisfaction.
