Why Simcenter Qsources?
Simcenter Qsources is a comprehensive suite of innovative sound and vibration excitation hardware to measure driving points and structural and vibroacoustic frequency response functions. A complete set of Qsources products cover the entire range of (reciprocal) transfer function measurements, focusing on performance attributes, such as system dynamics and sound quality.
Work with a comprehensive hardware suite
Simcenter Qsources offers a wide range of innovative hardware tools for sound and vibration excitation, from compact electrodynamic shakers to volume velocity monopole sources.
Improve repeatability
The specific design of the shakers provides easy access to hard-to-reach locations, allows for correct shaker angle and position accuracy, improves repeatability and signal-to-noise ratio, and delivers good excitation levels in the relevant frequency range of interest. This results in high-quality and accurate frequency response functions as input to structural dynamics and transfer path analysis.
Integrate with data acquisition hardware
Simcenter Qsources excitation hardware seamlessly integrates with Simcenter SCADAS data acquisition hardware and Simcenter Testlab acquisition and analysis software. This gives you a unique solution combination that exceeds current market standards for productivity, data accuracy and overall customer expectations.

Providing minimum mass loading while being self-supporting and self-aligning.
Simcenter Qsources capabilities
Amplifiers
Our measurement amplifier meets all necessary requirements to drive your acoustic and structural exciters. A low-power analog signal is accurately amplified to get the maximum out of the different shakers and sources.
High-frequency shaker
The high-frequency shaker generates a highly repeatable, high-frequency structural excitation in a minimum of space, with extremely low mass and stiffness loading of the test object. The inert mass is decoupled from the stinger dynamically by means of internal suspension. Its small size and light weight make it ideal for research on components such as PCB boards and electric motors, up to full product assemblies. The data can serve as input data for CAE model correlation and updating.
Integral shaker
The integral shaker helps to increase accuracy and productivity in your testing processes. Its compact size, high force, and wide frequency range make it efficient for structures such as complete vehicles, trimmed bodies, off-road equipment, and industrial installations. The optional in plane excitation adaptor is used to increase the accuracy and efficiency of the integral shaker.
Low-frequency monopole source
The low-frequency monopole source has been designed to measure vibro-acoustic transfer functions in and around vehicles. The negligible diffraction makes it an accurate omnidirectional sound source up to 2,000 hertz (Hz). This source, with integrated source-strength-sensor, also allows you to measure vibro-acoustic body noise transfer functions reciprocally.
Low-mid frequency source
The low-mid frequency source is used for producing high noise levels, more than sufficient for the excitation of complete vehicles. It is designed to be used in the 10 to 1,000 Hz frequency band an important frequency band in vehicle development. The integrated volume acceleration sensor gives real-time feedback of the emitted source strength. This source is typically used for transfer path analysis (TPA) of structure-borne or airborne noise and cabin vibro-acoustic modal analysis.
Mid-frequency volume velocity source
The mid-high frequency source is a general use monopole volume acceleration source with internal reference sensor. The source enables transfer function measurements in the frequency range of 200-10000Hz. It is currently in use in many R&D centers in all industry segments.
Miniature shaker
The miniature shaker is a vibration exciter that helps you perform accurate structural excitation in a minimum amount of space, providing you an ideal exciter for FRF testing from engine components up to full vehicle.
Its compact size allows users to excite systems at bearing locations inside powertrain components.
Thumper
The thumper shaker is designed for very low-frequency vibration ranges and narrow spaces. The force level makes FRF measurements possible on large structures, such as ships, windmills, and chemical industry installations and allows for vehicle body flexibility testing.
