Structural and Acoustic exciters
LMS Qsources Introduction
The investigation of the noise contributions of vehicle interior targets has become standard practice for vehicle manufacturers to gain insight in noise contributions, interface forces and system sensitivities. Because new technologies are being implemented and available time for testing time reduces, the need for dedicated testing devices increases. LMS uses its experience in NVH technology to continuously develop new acoustic and structural exciters under the brand name LMS Qsources. These enable ...
The LMS Qsources Integral Shaker, an Inertia Shaker with integrated sensors
In order to cover a broader range of applications, LMS Engineering Services developed another inertia shaker that includes the domain of mid-weight structural testing. In principle it has the same advantages as the LMS Qsources Miniature Shaker but it can be used to excite larger structures. The Integral Shaker is easy to mount and can be used on a very broad range of structures. Typical objects ...
The LMS Qsources Miniature Shaker, a Miniature Shaker with Integrated Sensors
This miniature shaker was developed by LMS Engineering Services to perform highly accurate structural excitation in a minimum of space. It provides excitation, but with extremely low mass and stiffness loading of the test-object. The system includes integrated force and acceleration transducers. This allows the engineer to obtain driving point FRFs in a very fast way. The force generated by this structural ...
The LMS Qsources Measurement Amplifier, a complete solution for hardware power supply
The LMS Qsources Measurement Amplifier is the perfect link between the LMS Difa Frontend and all available LMS Excitation hardware. This dedicated amplifier is able to power both Sound Sources and Structural Exciters offered by LMS. The Measurement Power Amplifier allows the user to transform low power signals from signal generators, like front-ends, PC-audiocards, headphone exit, sine or noise generators, ...
LMS Qsources Mid Frequency Volume Source – a multifunctional acoustic exciter
Volume acceleration sound sources are sophisticated acoustic excitation devices that produce high levels of noise. This acoustic exciter covers the 200 to 8000 Hz frequency band and provides an accurate real-time reference signal of the acoustic source strength.The mid to high frequency source is a tube type of source, the sound is generated in a high pressure driver and transferred to the nozzle ...
The LMS Qsources Low Frequency Volume source
Volume acceleration sound sources are sophisticated acoustic excitation devices. The source is capable of producing very high noise levels, more than sufficient for excitation of complete vehicles. The integrated volume acceleration sensor gives a real-time feedback of the source strength and can directly be used as a reference for FRF measurements without any post-processing.The LMS low-mid frequency source is designed to be used in the 10 to 800 Hz frequency band which covers the most important ...
The LMS Qsources Miniature Volume Velocity Source
In order to expand the limits of current excitation devices, LMS developed a new highly compact sound source-receiver. This acoustic exciter can be used as a very compact low-level volume displacement source. But the same acoustic exciter can also be used as a low-frequency microphone. The sound source is especially suitable for lower frequency reciprocal acoustic transfer function measurements in special situations. With only 74mm length, this extremely compact sound source-receiver can be used ...
The LMS Qsources Panel Pressure Exciter – A contactless exciter
Interior noise of a conventional vehicle can be decomposed in several contributors like: powertrain, road & wind noise. Nowadays, engines are becoming more and more silent, so more, not so common, sources will get more dominant in interior noise. The test techniques used to analyse engine contribution are not always dedicated enough to analyse the new generation of noise sources. Because the need for dedicated testing devices increased, LMS used its experience to develop a new tool. This ...
