New NVH damper test system for structure-borne noise assessment

Byron Saari
Principal staff engineer
MTS Systems
USA
Demands for improved suspension NVH are driven by quiet EV and comfort-focused autonomous vehicle trends. Noise is emitted from the damper through airborne and structure-borne transfer paths. MTS has developed a unique damper test system to evaluate structure-borne noise and vibration. Traditional damper systems evaluate damper characteristics in the lower suspension motion frequencies, typically less than 50 Hz. For evaluating structure-borne noise, precise excitation and measurement in audible frequencies up to 800Hz is necessary. This new NVH damper system achieves high frequencies using an electric actuator, high resonant frequency frame and high bandwidth transducers.

Driven by robotic test drivers, ASI's autonomous vehicles are capable of tighter, more accurate positioning than manned vehicles can safely perform. Swarming also provides a solution that allows customers to import simulation scenarios into Mobius, ASI’s command center software and let ASI robots perform these scenarios on physical vehicles.

The importance of synchronization and the mechanisms available

Dave Gallop
BDM ground vehicles and autonomous systems
Dewesoft LLC
USA
Many connected devices use mechanisms for synchronization. Often there is a specific technology that is applied and utilized to assure information is gathered in a manner that allows correlation between devices regardless of the proximities involved. These technologies enable assurances that signals align to acceptable levels but differ dramatically in their behavior and phase alignment differences. With emerging timing protocols such as those needed in time-sensitive networks (TSN), it may be worth reviewing how each behaves and if your devices comply or can be made compliant with the synchronization mechanism you choose. This is a review of some used.

Realistic radar reflections for validation of ADAS/AD functions

Aaron Newman
Business development
Keysight Technologies
USA
There are numerous examples of ADAS failing on production vehicles in real road situations, whether due to challenging weather conditions, incomplete scenario testing, or even unimagined situations. Model-in-the-loop (MIL) and software-in-the-loop (SIL) fulfill important parts of the design cycle, but when systems reach the hardware-in-the-loop (HIL) stage, realistic simulation of radar sensors in 3D dynamic environments is non-existent. Or has been. We present a new approach to provide a realistic reflection environment, including things like ground clutter, guard rail and overpass returns with independent motion and reflection characteristics.

DAY 1 PM

Evaluation of high-speed digital media for automotive cabling

Brian Walker
Senior RF engineer SME (subject matter expert)

However, for testing ADAS/AD (advanced driver assistance systems/autonomous driving) features, these real vehicle tests become more and more complex. To reduce the effort of creating this real environment, a simulated environment is used instead. This is achieved by measuring the real vehicle movements and feeding them into a virtual clone simulated on a real-time system.

Understanding measurement uncertainty for electric drive

Mitchell Marks
Business development - electrification
HBK
USA
To optimize the performance of an electric powertrain, its efficiency must be verified with measurements both during development and in operation. These measurements will have an associated measurement uncertainty (MU) due to the accuracy of the measuring device and the environmental conditions of the test. The MU indicates the probability that a measurement result is in a specified interval around the ‘true’ value. The measurement result, therefore, generally does not match the actual value, so each real measurement is subject to a certain measurement deviation/error. This measurement error propagates from the measured quantities to other quantities calculated from these.
