Precise and Comprehensive Vehicle Testing with HBK from NVMS

Proven, For Today and Tomorrow

‍

The landscape of automotive testing is evolving, driven by the need for more accurate, efficient, and comprehensive evaluation methods. HBK (Hottinger Brüel & Kjær) have been leaders in this field for decades, offering integrated solutions that bridge the gap between virtual simulations and real-world testing. With technologies like QuantumX, SomatXR, and the CatMan software suite, HBK provides an unparalleled approach to capturing and analysing critical test data using an instrument eco-system that can start small and grow as needed.

‍

With demand for electric motor-based drivetrains growing constantly, HBK’s high-speed Genesis platform is a part of this exciting era, within R&D departments of the largest automotive manufacturers, as well as emerging companies innovating for tomorrow’s electric vehicles, drones, and aviation. Vehicle testing has always been a cornerstone of automotive development, ensuring that every component performs optimally under various conditions; regardless of whether the powertrain is combustion or electric.

‍

These Tests May Include:

• Steering Performance and Kinematics: Using precision instruments to measure steering angles, torque, and response times during manoeuvres, like step steer and slalom tests.
• Brake Testing: Conducting rigorous assessments of braking systems under various conditions, including emergency braking and ABS performance.
• ADAS (Advanced Driver Assistance Systems) Evaluations: Testing features such as Adaptive Cruise Control (ACC) and Autonomous Emergency Braking (AEB) to ensure reliability and safety.
• Electric Powertrain Testing has emerged as demand for cleaner vehicles drives innovation away from petrol powered cars. Electric Powertrain Testing from HBK isn’t just a quick-fix adaptation of a standard DAQ platform, it is the result of close collaboration with global motoring OEMs since the term ‘Hybrid’ took on its modern automotive meaning.

Combined Electric and Conventional Testing

‍

The current push for electrification puts pressure on companies to bring products to the market faster and at lower cost. Our single-system solution allows you to combine powertrain and NVH testing and better understand cross-domain dependencies.

‍

One of these challenges is torque ripple, which has several implications including control, power output, noise, vibration, and durability. Torque ripple can be described as the variance of output torque as the motor rotates. HBK domain expertise in this area is unbeaten with world leading highspeed DAQ and high precision torque transducers.

‍

HBK torque transducers – such as this T12HP – can be equipped with optical rotational speed measurement.

‍

At NVMS we can provide unique support for your torque, stress, strain, or tortional test and measurement needs by any means; whether using off the shelf transducers or working with your designs to produce customised for purpose strain gauges, sensing elements, and electronics.
