AUTOMOTIVE / GROUND VEHICLES
Driving Simulation In Top Gear
Today’s automotive engineers want the most realistic simulated driving scenarios, capturing essential vehicle characteristics, including sound. A driving simulator facilitates active safety tests and lets drivers evaluate different set-ups and feel the dynamics of a virtual car.
Multiple Vehicle Pass-by Tests
Engineers can assess noise from many vehicles at the same time with data acquisition synchronized by GPS.
Sorting out the sources of sound
The latest research into Blind Source Separation (BSS) – a technique that involves separating a mixture of sounds – indicates that it is a good method for assisting the automotive industry in evaluating noise from different sources. Despite the complex algorithms involved, results suggest BSS may be a superior and more intuitive technique compared to the widely used Source Path Contribution (SPC) analysis.
Predicting EV Warning Sounds
Electric vehicles (EVs) are so quiet at low speeds that they can be a danger to pedestrians, cyclists, and other road users. So the challenge for car manufacturers is to create sounds that are detectable but not annoying.
Cutting the commute
Only in the final hot weeks of late summer do combine harvesters appear, carving their dusty trails through dry cornfields. To exploit every last minute while conditions are optimal, New Holland’s developers work hard to reduce the time driving between fields.
Driving brand awareness
At Borla, we develop and build the world’s finest aftermarket exhaust systems for high-performance vehicles. In fact, we are the originators of this market, which has given us a unique understanding of what it takes to create the right product for a highly discerning customer.
PULSE makes explosive readings
Building warships from composite materials and designing and building stealth submarines are specialities of Swedish defence shipbuilder Kockums AB. When designing these types of crafts, crucial demands are placed on their noise, vibration, and shock response properties. To ensure that these stringent requirements are fulfilled, a thorough knowledge of structures and material properties is a prerequisite, backed up by extensive testing to validate the theoretical designs.
All quiet on board
Noise is a significant issue for anyone working on ships. Even moderate noise and vibration can affect comfort and lead to a drop in performance. Professor Hideyuki Shuri, an authority on ship noise, has been working for many years to overcome the challenges.
