Understanding Automotive Engine Noise

One of the most significant pressures on car manufacturers today is sound quality. There are many factors that engineers must consider when analyzing the sound emitted by a car. Aside from being a marketing tool, there are now government regulations on sound. New developing technologies including hands-free mobile and speech recognition require the clear voice …

Automotive Noise Optimization with Simulation Software

Using Simulation Software to Predict Automotive NVH   One of the most pressing challenges for today’s automotive manufacturers is to make lighter cars. A lighter car will maintain a lower level of gas consumption and thus is more eco-friendly. To achieve this goal, many companies switched from aluminum to composite materials and put smaller engines …

Identifying the Acoustic Contribution to Interior Noise

The aerodynamic sources acting on a car side window, generally defined as the small wavelength sources such as turbulent eddies and boundary layer structures, are generally much larger in amplitude than the acoustic sources, those with longer wavelengths. So naturally you would expect that the aerodynamic sources have a much greater contribution on vehicle interior …

Tuning Acoustic Quality of Audio Devices with Simulation

  When designing an audio device, the most important thing for an engineer to consider is the quality of the sound. Quality is what makes the device valuable and differentiates it from competitors. Audio device manufacturing companies experience extremely high product development costs due to repetitive and expensive physical testing. In addition to the need …

New Trailer Suspension Designs Tested in Hours Compared to Days or Weeks

Overview The primary function of heavy duty trailer suspensions is to link the trailer to its wheels. This provides a compliant connection which protects the trailer cargo from the shock and vibration inputs developed at the road surface. In addition, the suspension must meet the customers’ expectations for usable life, and do so while being …

Adams dramatically reduces time to design child safety latch at Kiekert

Car doors are immensely complex systems that serve an immensely important function – safety. The child latch is an additional safety measure, one of many functions a side door latch performs. The child safety lock temporarily disables the operation of the inside door handle. When it is engaged, the rear doors can only be opened …
