Some of the most significant challenges facing the automotive industry include raw material cost, light-weighting and achieving mass production. These are direct consequences of environmental requirements becoming more rigorous as concern about carbon emissions grows. Moreover, the use of carbon fiber is an important part of the answer to these problems but brings on its own set of issues that need to …
Airplane noise is an important factor for airlines to consider due to several industry changes in recent years. Increased competition, more air traffic, and construction of communities near airports has created several new issues for aerospace engineers to take into consideration, including quality perception from customers and new regulations from both local and federal governments. Turbofan …
Acoustic Simulation For the Aeronautical Industry With the expansion of air travel around the world, competition between airlines has become much tougher. Airplane companies are under constant pressure from governments around the world to reduce noise and from consumers to reduce the cost of air travel. For many companies, noise is a chronic …
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 …
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 …
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 …
