Mechanical and Seismic Vibration Services

ISE is a recognized leader in mechanical and dynamic vibration analysis, and has a full range of portable modal analysis testing equipment capable of extracting frequency, damping, and mode shape information from structures such as buildings, railcars, automobiles, bridges, aircraft and more. This information enables our engineers to generate a complete "picture" of the test specimen's dynamic behavior. Input excitation levels of up to 5,000 pounds force are possible using our modally tuned 12-pound sledgehammer.

The vibration services provided by ISE are designed to provide assistance to groups and individuals requiring a timely solution to both large and small scale dynamic excitation problems. Projects where frequency response, vibratory interference, and operational performance are critical, will find our services indispensable.

Vibration services provided by ISE include:

• Complete modal testing to determine dynamic structural response.
• Free- and forced-response monitoring of offshore and rail structures.
• Building vibration impact studies (monitoring, historic, residential).
• Remote blast monitoring / recording system deployment.
• Ground transmissibility and wave attenuation studies.
• Damping estimations.
• Seismic loading analyses.
• Vibration reduction and base isolation strategies.
• Residential, commercial, and mass transportation vibration monitoring.
• Elastic residual force analyses - damage detection and monitoring.
• Construction analyses (drilling, tunneling, blasting).
• Dynamic laboratory testing using in-house 100-pound shake table.
