Custom Testing for Load Certification or FEA Certification.
Simulation of anticipated loading(pressure, force, or both) can aid in evaluating the effects of service when designing a part or trying to determine the cause of a part’s failure.
Because of our familiarity with stress analysis, many problems can be resolved with conventional hand calculations. For those instances when that is not practical, we can instead produce a digital 3D model which will allow the prediction of stress, deflection, or both the ability to quickly solve stress analysis problems using a combination of these methods aids our design of new products or evaluation of the cause of failure of existing items.

Types: Dynamic, Wireless, Baked-On, or Bridges
For: Structures, Shaft Power, or Torque & Remote Monitoring
We use strain gauges with dynamic computer data acquisition and even telemetry from rotating shafts to answer questions of how stress is affected by use.
We have utilized this method during bridge repair and can provide this service where rope access is required viz collaboration with FIT Engineering.
Bartlett engineering uses specialized instruments to measure the frequency and amplitude of vibrations. We also can use computer models to evaluate the resonant frequencies of suspected culprits. This same models can then be modified to test the effectiveness of the proposed system changes.
Another type of particularly vexing vibration problem is one that only occurs periodically due to such things as changes in wind speed or equipment loading.
Bartlett Engineering has equipment that with allow us to automatically monitor systems over extended periods of time, and we have even configured that equipment to be able to remotely monitor and control that test equipment to be able to remotely monitor and control that test equipment from our offices. We have used this systems for remotely monitoring the stresses in our 100 locations on a ridge for several months.
We have also used this systems to monitor the stresses in a rotating gearbox shaft. In that application we used wireless telemetry strain gauge equipment on the rotating shaft.
Vibrations that you notice are usually a sign that something is not as it should be. The result if excessive vibrations can range from bothersome noise to excessive cyclical stresses that lead to shortened fatigue life. A vibration typically requires a system with a resonant frequency that is close to an excitation frequency. the vibration can be reduced by changing the resonant frequency of the system, reducing the intensity of the exciting source, or changing the frequency of the exciting source.
