MSC Nastran – Simulating Reality, Delivering Certainty

Use of FEA in Elevator Design and Test

Product Marketing — Thu, 23 Jun 2016 17:00:55 +0000

Schindler Elevator’s offerings range from passenger elevators suitable for small blocks of apartments to sophisticated transport solutions for skyscrapers. Service elevators ensure the stress-free movement of goods and people in shopping centers, office buildings and railway stations. Bed elevators provide for the smooth and vibration-free movement of patients and equipment in hospitals. In industrial buildings, many of the hoists and small good elevators in use are supplied by Schindler, while glass cabin elevators in tall buildings offer both a novel experience and a feeling of safety. It is hard to imagine public transport without elevators, which are often heavily used and must therefore meet demanding requirements in availability and serviceability.

The company’s research and development facility in Switzerland devises complete elevator systems as well as components for all applications. Here, CAE is used to find reliable and energy-efficient solutions which make the most efficient use of materials. The programs SimXpert and MSC Nastran from MSC Software are used for structural calculations using the finite element method (FE). These are used, for example, to simulate the wall fixings of elevators and determine whether deformations and loadings remain within the permissible range. The resulting design and its verification encompass the guiding system and the cabin, counterweight and drive components. In addition to static (strength) calculations, dynamic and vibration analyses are also carried out with the aid of FE methods. The field of nonlinear FE calculations is also of central significance.

Nonlinear Analysis in MSC Nastran to Reduce Design Bottlenecks

Product Marketing — Tue, 14 Jun 2016 17:00:47 +0000

Sporadic use of advanced finite element analysis (FEA) software, such as nonlinear analysis by design engineers, can result in either excessive refresher training time or a bottleneck while in the queue for an analyst. The cause is a result of different types of solvers requiring different models. Commercially available translators can help, but still require significant amounts of cleanup. However, by integrating solvers in MSC Nastran’s SOL 600, the same model in the familiar MSC Nastran format can be used for both liner and MSC Marc nonlinear analysis.

Multidisciplinary Solutions For Brake Squeal

Product Marketing — Tue, 03 May 2016 17:48:51 +0000

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. ...

Acoustic Simulation for Automotive and Heavy Equipment Industries

Product Marketing — Tue, 26 Apr 2016 17:03:15 +0000

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

Product Marketing — Fri, 22 Apr 2016 16:19:44 +0000

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

Product Marketing — Thu, 21 Apr 2016 18:15:27 +0000

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 ...

Understanding Automotive Engine Noise

Realizing the Full Value of Aerospace Composite Design

Product Marketing — Tue, 24 Sep 2013 18:31:33 +0000

The complexity of composites vs. traditional metallic materials has forced aerospace manufacturers to complete 7-20x more tests than before across all levels of the validation pyramid. With smaller tests costing around $1k-$5K, and the larger tests costing up to $1M-$3M, a significant barrier has been presented in terms of cost and time to validate their ...
