This article was originally posted by Bob Schmitz, Senior Business Development Manager for e-Xstream engineering on Composites World magazine. Traditionally we have designed, characterized new materials with physical testing by using simple coupon tests, which are affordable and the results have generally been accepted as fact, even if the sample size is small. However, material science has …
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 …
Although engineers have started to use simulation software to test brake squeal, its complex nature usually requires more than one different software and discipline. This makes it difficult to transfer data from one software to another and to work in different environments. To address complex brake squeal in one environment, multidisciplinary solutions (MD) can be used. …
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 …
