The Boeing Company

Overview:
Boeing is responsible for design, development, construction, and integration of the International Space Station (ISS) - Integrated on-orbit from a series of segments transported up to the Station by the Shuttle. MSC ADAMS was used for functional verification of the attachment interface mechanisms, which required a thorough representation of the contacting geometry. The MSC ADAMS solid-to-solid contact force statement allowed simulation of the segment-to-segment attachment including various combinations of contact feature misalignment. The analysis reduced contact model development and helped Boeing minimize the possibility of introducing an error by providing stable, accurate solid-to-solid models.
Challenge:
The segment-to-segment attachment interface includes ready-to-latch indicators, coarse and fine alignment guides, a capture latch, and supporting interface structure. Each of the contacting elements was idealized as one or more of the following contact representations: sphere to plane, line to line, line to arc, sphere to cone, sphere to torus, sphere to cylinder, arc to interior of cone, and arc to exterior of cone. Each of the contact equations was resolved to a pair of points representing the minimum distance between any two contacting elements.
Solution:
Model validation was accomplished using component-level tests of the contacting features. Testing was performed on the coarse guides, fine guides, and the capture latch. Testing was performed by slowly moving the contacting elements together while measuring test table strut displacement and force. The results of the tests were then compared with simulation results.

Moeller GmbH

Overview:
Moeller GmbH, a major innovator in switchgear and safety solutions for a wide range of industries, used MSC ADAMS for studies and calculations in new switchgear development, and to analyze improvements in existing products. Moeller engineers performed various tests on the same virtual model, inlcuding forces and load calculations, resulting in fewer physical prototypes and high-speed recordings. Thanks to MSC ADAMS, Moeller reduced the development time of new and modified products and improved the quality of existing products.
Challenge:
In order to effectively protect machines and engines, the circuit breakers must operate as predicted and therefore must be tested beforehand. Experimental hardware tests of circuit breakers require the building of a realistic prototype including all essential sub-assemblies and all necessary materials, making these tests laborious, time-consuming and expensive. Before using computer-aided engineering (CAE) software, the AE engineers performed motion analyses of their switches using high-speed video recordings of the physical prototype. Static calculations were done manually with functions and loads - a demanding and tedious method, and a major handicap in the field of advanced engineering.
Solution:
Since computer-aided design (CAD) software was already in use at Moeller for switch development, it was a logical step to implement CAE software for functional analysis of the switchgear. Among several software packages, MSC ADAMS was chosen to be the most suitable for multibody simulation because it enables the engineers to perform a complete analysis of the assembly as well as dynamic calculation of the loads.
Benefits:
  • Higher overall quality of the product could be improved
  • Results are more accurate and faster
  • The MSC ADAMS post-processor offers significant plots and animations, which quickly reveal the right development direction.
  • With precise results, management can come to their decisions more quickly and with more confidence
  • The number of hardware prototypes can be significantly reduced

Beacon Power's Flywheel Energy Storage System reduces Material Costs By 50%

Overview:
Physical testing of prototypes is mainly used as a last check before a new design is approved, providing correlation between simulation and the actual results. Because of the success that Beacon Power has achieved by utilizing simulation early in the design process, most of the companies engineers are being trained in simulation, using MSC Patran and MSC Nastran, which results in a stronger technical organization, directly impacting both the product and processes, lowering costs and improving the final product.
Challenge:
With a 150 lb. rotor spinning at an angular speed in the mid 20 KRPM range, stress, vibration, safety containment and thermal issues all must be addressed when designing a flywheel energy storage system. However, developing prototypes for physical testing is time and cost prohibitive.
Solution:
To improve design efficiency, MSC Patran, MSC Nastran, MSC Dytran, were deployed to simulate problems before incurring the expense of prototypes and physical testing. As a side benefit, Beacon Power improved its designs, while reducing material costs 50%.

MSC Software Professional Services Team Enables Development of Patented, Energy Absorbing Bus Bumper System

Overview:
The high up-front cost of product development was hindering the development of an innovative energy absorbing bus bumper system conceived by Talfourd-Jones Inc., parts makers for leading original equipment manufacturers. By retaining the simulation services of MSC.Software Professional Services, Talfourd-Jones Inc. was able to test and prove the concept for the bumper system before investing in the tooling required to produce the technology.

Challenge:
The bumper must protect the bus from any damage as a result of 6.5-mph direct impact into a rigid barrier and a corner impact from a common carriage. In addition, the bumper must return to pre-impact shape within 10 minutes of the impact.
Solution:
The primary system for meeting the impact requirements is through energy absorbing bumpers mounted on the front and rear. To meet this requirement, the Reflex bumper was designed to progressively collapse, cushioning the vehicle from a collision. Following impact, the bumpers return to their original shape without permanent damage or degradation in strength.
Benefits:
  • Easy to adapt for a modular design, minimizing tool costs and allowing easy installation for the bus service departments.
  • Easily modified, so the design can be tailored to other energy absorbing requirements by modifying cell wall thickness.
  • Easy interface with support beam, by incorporating a simple tongue for insertion into beam groove.
  • Provides a strong vertical support for front bumper step requirements.
