Response Dynamics
Response Dynamics works within the United States and worldwide as acoustic and vibration consultants, providing unmatched services in advanced vibration analysis, including: acoustic analysis, vibration testing, acoustic testing, vibration monitoring and noise monitoring services, as well as engineering design. For 35 years we have combined our engineering expertise in vibration testing, acoustic noise, strain, thermal heat flow, airflow, and magnetic fields.

We utilize our specialized knowledge and skills to work with and be a part of our clients' teams. Please feel free to call us to discuss your team's product, system or facility issues.

We have worked on a myriad of systems and facilities, with responses ranging from subnanometer amplitude disturbances of electron microscopes, interferometers, and atomic force microscopes, to micron amplitude motions of giant telescopes in Hawaii and in the Chilean Andes, to meter amplitude storm response of offshore oil rigs, to name just a few.

Working in the roles of vibration consultant, acoustic consultant, and EMF consultant, we partner with R&D teams, on the design and development of hundreds of critical systems, products and facilities.

This is the heart of vibration testing and key to make confounding vibration issues understandable.
Our vibration testing, structural dynamics and modal analysis consulting services have helped push the limits of technologies and cutting edge designs for over 30 years.
Is the vibration problem caused by excessively large forces, do we have a structural resonance problem, or some of both?
How will vibration levels change if we move the force excitation to a new location on the structure, and/or if we change the force axis?
Effective vibration isolation is critical to the performance of many systems.
It is often much more challenging than expected because the structural dynamics of the supporting structure, and the isolated structure, also affect the isolation performance.
Isolation resonances can often create other vibration problems and confound an engineering team.
We have successfully designed vibration isolation into countless systems over the years using unique custom solutions as well as adapting standard components and applying them properly to the design.
Sensitivity testing involves making predictions of system response to environmental disturbance.
The significance and importance of the system sensitivity estimates is very often overlooked.
This gets companies in trouble and is one of the top reasons why we are called upon to provide timely solutions.
Most teams are focused on getting their product to work and get it out the door.
An engineering team will often not know how to quantify what to expect in the customer environment and how to test for those expected disturbances.
Response Dynamics has made diagnostic testing our core focus for over 30 years.
We do this detective work well because we have particular expertise in structural dynamics and how it relates to vibration and acoustic noise issues on a myriad of levels.
We enjoy this work because it stays interesting and draws on multiple disciplines in engineering and science.
We most often characterize a problem first and work from known conditions, and stay in "the known" as we proceed by making sense of what we observe as we move forward.
Shake table testing is often used in prototype analysis, failure analysis, shipping vibration testing and vibration sensitivity testing.
We know what boundary conditions are vital for effective testing, how and where to instrument the system, how to deal with off-axis excitation (often not accounted for), and make the most efficient use of testing time.
Let us have a look at your system and any specified vibration criteria before the shake test is designed.
We can interpret the criteria, make sure it is applied appropriately, and make recommendations that will save valuable time and expense.
