This innovative approach to sound suppression focuses on minimizing noise, vibration, and harshness (NVH) in vehicles, ensuring a quieter and more relaxed ride for the driver and passengers.The Premise of QuietTuning QuietTuning is an integrated engineering approach that involves techniques to reduce ...
When more than one physic is interacting (such as fluids and structures, or structures and electromagnetics), they are said to be “coupled.” These interactions happen all around us all the time, from tapping the screens on our phones to driving our cars over bumpy roads. Common examples ...
NVH: Controlling thenoise, vibration, and harshness (NVH)levels within a vehicle is critical to passenger comfort and overall experience. By using multibody dynamics simulation, automotive engineers can identify the sources of vibration and sound emitting from all parts of a car and determine the be...
High-speed CAN is faster than low speed, but the bandwidth requirement of new automotive applications is increasing every year, so automobile OEMs are now installing CAN FD into new cars. CAN FD has been described tongue-in-cheek as “CAN on steroids.” ...

What Are Cars Materials Used in Auto Parts Manufacturing By Prose Corporation on 25/10/2024 The automotive industry is the largest consumer of raw materials of natural or derived origin. In the past few years, users have mainly focused on...
What does all of this mean in a practical sense? An air curtain helps a vehicle achieve better performance, consume less fuel, and emit fewer CO2 emissions, not to mention less noise, vibration, and harshness (NVH) experienced by the driver and occupants. In other words, the vehicle deliver...
Although these curves may work very well to control overall NVH levels, they may not be very useful to control the final sound perception of the vehicle. In other words: How my vehicle will spark a certain emotion to the driver is not captured in this process. From a set...
New friction requirements.Noise, vibration and harshness (NVH) during operation is an increasingly important concern for manufacturers of electrified vehicles in order to provide a more satisfying experience for the driver. The right driveline fluid formulation can provide outstanding friction performance by...
Where these requirements are concerned, the engineers benefit from their long experience in NVH testing. Almost 200: This is how many prototypes and pre-series vehicles are built for the test programme. Several hundred: Before being released for production, the vehicle must ...
