Konu Başlığı : How to determine the root cause of excessive vibration?
Tarih : 17 Ağustos 2012
Saat : 11:00 AM EST

Excessive vibration level is one of the pains faced by engineers. The consequences of excessive vibration level are different for each type of structures. The level of severity can range from low performance to structural failure.

For example, when manufacturing a mechanical machine, it’s primordial to remedy excessive vibration level in order to increase performance, reduce noise levels and machine failure occurrences. Better performing machines produce more goods in a shorter time. And silent machines are not a nice-to-have but a necessity for low noise working environments.
Observing the operational vibration level is the first step. Meanwhile, finding out the root causes of excessive vibration level, by identifying structural resonance and critical load, will be more efficient. This web seminar will mainly explain how to identify structural resonance based on test results and techniques such as operational deflection shape, modal analysis and operational modal analysis.

In this web seminar you will learn:
– How structural resonance cause excessive vibration
– How to identify structural resonance
– Difference between operational deflection shape, modal analysis and operational modal analysis
– When to use operational deflection shape, modal analysis and operational modal analysis

Who Should attend
– Anyone who wants to solve efficiently their noise and vibration problem
– Anyone who wants to accelerate their development process
– Anyone who has excessive vibration problem on their product

Intake / Exhaust Performance Simulation
TARIH : 06.08.2012
SAAT : 18:00 TSI

Air intake systems as well as exhaust systems are significant noise sources, related to both interior and exterior noise of vehicles. As regards to interior noise, both reducing noise from intake systems and tuning the sound is key to optimize passenger comfort. For exterior noise characterization, legislation for pass-by-noise forms a major concern.
In this web seminar you will learn:
– How to analyze the Transmission Loss of intake and exhaust systems
– How different measures improve the acoustic performance of intake and exhaust systems
– The effect of temperature, flow and perforations on the noise characteristics

Who Should attend
– Design and Simulation engineers for Intakes and Exhaust
– Intake and Exhaust program managers

Is Automated Modal Analysis a Reality?
TARIH : 10.08.2012
SAAT : 18:00 TSI

While performing modal analysis, the manual separation of the physical poles on the stabilization diagram from the spurious, mathematical ones, requires quite some experience and will inevitable lead to highly operator-dependant results. This problem is most prominent in the case of highly damped structures where modes tend to mix up or when there are a high number of modes in the frequency range of interest. With the increasing use of modal analysis as a standard tool by many, also less experienced users, there is a strong need to also automate this part of the analysis process.
In this web seminar you will learn:
– How to get clutter-free stabilization diagrams using the LMS PolyMAX estimator
– Which procedures were used to capture expert knowledge in the automatic stabilization diagram assessment tools
– About the benefits of automated modal analysis
– How automated modal analysis is performed in practice
