Focus
on Fatigue |
MoreVision has developed a number of programs to post-process finite element
results, calculate fatigue damage and to plot damage directly onto the FE
mesh. The assessments cover code of practices used in many countries (UK -
BS7608, France -UIC 515-4 Goodman Diagram, German DIN 15 018, Swedish Volvo
standards) |

How to Solve
Vibration and Noise Problems |
|
BEFORE DYNAMIC ANALYSIS TECHNIQUES
 On November 7, 1940, at approximately 11:00 AM, the first Tacoma
Narrows suspension bridge collapsed due to wind-induced vibrations.
Situated on the Tacoma Narrows, near the city of
Tacoma, Washington, the bridge had only been open for traffic a few
months. Within a short space of time the bridge collapsed. |

HOW CAN A DYNAMIC ANALYSIS HELP ME?
Dynamic analysis
is typically used to design out potential noise and vibration
problems, or to evaluate the impact of transient loads. Modal analysis
is used to identify natural frequencies, and enables the designer to
avoid excitation and eliminate excessive vibration. Animations are
easily produced to provide valuable insight into how the structure
will behave when excited.
Harmonic response analysis is used to
determine the steady-state response of a linear structure to
sinusoidal loads, and enables the evaluation of resistance to
sustained forced vibration. Transient dynamic analysis is used to
determine the response to general time-dependent loads. Typical
applications include seismic or explosive events. Rotordynamic
analysis is important when designing or troubleshooting rotating
systems. By modelling the rotating geometry and its dynamic
characteristics, such as stiffness and damping, the critical speeds
can be predicted. Design adjustments can then be made to avoid
continuous running at those speeds. |

DYNAMIC TESTING
 Test
measurements can also to determine dynamic
response. See our case study on bolt fatigue failure investigation

Partnering
Client Design Teams |
 Will it fall off? Is it strong
enough? How long will it last? These are the questions on the minds of many
designers. MoreVision can team up to perform simple strength assessments to
allow designers to move forward with the confidence that their designs will
ultimately satisfy structural criteria. |

Failure
Investigations |
|
Simply strengthening an area
may not give you the results you want and could make the problem worse.
Before a solution can even be considered it is imperative that the mechanics
of the failure are completely understood. |
