Simulating Brake Squeal Noise

Brake squeal is one of the most challenging problems that car manufacturers have today. It occurs as a result of the vibration of the brake components such as brake disc and brake pads and therefore it disturbs the driver and passengers. Furthermore, because of its complex nature it is hard to completely understand the causes …

Acoustic Simulation for Automotive and Heavy Equipment Industries

At present, noise quality is a crucial issue for automotive and heavy machinery manufacturers. In addition to the strict governmental regulations, it is important for automobiles to maintain the perception of quality in costumer’s mind. On the other hand, the sound of heavy machinery is a safety issue. Loud noises can make it harder for …

Use of Multidiscipline Solutions to Improve Automotive Noise, Vibration and Harshness

Simulation software is being used extensively around the world due to their accuracy and cost-effectiveness. Instead of using different simulation tools for every different type of testing process, engineers can use multidiscipline tools to better improve NVH (noise, vibration, harshness). MD solution tools can be used for many different areas of testing, including:  Analysis of …

Reducing Automotive Engine Noise with Multidiscipline Simulation

While companies can solve automotive engine noise problems by using engine mounts to stop vibration and the firewall to stop airborne noise, these solutions are not sustainable if one wishes to maintain quality. Therefore, car manufacturers taking advantage of finite element analysis (FEA) software to better understand noise and vibration. FEA can be used to …
