噪声、振动与声振粗糙度

在 ACS，我们已申请专利的隔热罩单铆钉隔离器及生产工序正引发着隔热、减振/噪声、振动与声振粗糙度 (NVH) 技术的革命。为了改进现有的装配，我们创新的设计淘汰了多部件构造及其高成本的装配流程。

什么是噪声、振动与声振粗糙度？

Noise, Vibration and Harshness (NVH) is used to describe the experience and measurement of unwanted sound and movement a vehicle or mechanical system produces during operation. Commonly used in the automotive industry, NVH evaluates how noise, vibrations, and overall ride discomfort impact the driver and passenger experience. These factors are influenced by everything from engine performance and road conditions to mechanical components and aerodynamic flow.

Often referred to as noise attenuation or vibration dampening, noise vibration harshness is a key focus in automotive noise reduction technology. Important to product development and design, reducing NVH contributes to the enhanced comfort, quality and performance of vehicles and other mechanical systems.

Benefits of NVH Reduction

Improving noise vibration harshness not only contributes to a quieter experience, but also increases the perceived value of a product. Manufacturers use a range of vibration dampening products and sounds-deadening materials to:

  • Reduce vehicle noise and harshness for a smoother, quieter driving experience
  • Minimize vibration in engines, suspension systems, and cabin components
  • Improve durability by protecting sensitive components from mechanical stress
  • Enhance comfort and performance for both drivers and passengers

Effective NVH solutions are essential in today’s vehicles, especially as electric and hybrid models demand even more precise sound control in the absence of traditional engine noise.

What is a Heat Shield?

A heat shield is a protective barrier used in vehicles to guard key components from high temperatures produced by the engine and exhaust system. Depending on their purpose, whether to reflect, absorb, or disperse heat, heat shields are made from various materials. All types help extend engine lifespan, improve performance, and enhance safety by minimizing heat exposure to nearby parts.

ACS’ “One Piece” Isolator

Our patented One Piece Isolator is engineered to secure heat shields to components such as manifolds, turbochargers, and catalytic converters, while also providing noise, vibration, and harshness protection.

Unlike traditional isolators, which use two mechanically attached washers that can detach in transit, our solution forms the compressed knitted mesh directly to the heat shield. This integrated design withstands extreme temperatures beyond the limits of most elastomers and offers superior NVH dampening. The result is improved product integrity, reduced scrap, and greater automation compatibility.
