Manufacturing Simulation Reduces Development Costs and Time in Cold Forming Tool Design

Product Marketing — Tue, 28 Jun 2016 18:38:40 +0000

Omni-Lite Industries is an advanced material company. They recently designed a new part that was exhibiting a unique material flow. The part was cold formed out of 1100 aluminum material.

The initial tool design was completed and reviewed using the Simufact.forming simulation. Upon initial review, everything seemed to be acceptable, with the exception of the volume of material in the flange of the part. The second station trap extrusion die radius was then reduced in order to accommodate the material volume requirements.

Use of FEA in Elevator Design and Test

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.

Finite Element Analysis of a UAV Wing

Product Marketing — Wed, 22 Jun 2016 17:00:38 +0000

AeroVironment’s Global Observer is an unmanned aircraft with the wingspan of a Boeing 767 but less than 10% of the weight designed to provide communications and sensing for flights lasting up to one week at up to 65,000 feet. With a maximum wing loading of only 3.5 pounds per square feet, the wingtip deflects greater than 22 feet at its design limit load.

MSC Nastran was utilized to develop nonlinear stress, structural dynamic and aeroelastic finite element models. The structural dynamics model was correlated to a ground vibration test, both of which had to accommodate the apparent mass of the air, which is atypical. The ultimate test of the nonlinear stress model was correlation with the static wing load test.

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 Helps Airbus Reduce Aircraft Noise

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 ...
