Seismic

Recreating a seismic event, or earthquake, in the laboratory requires the combination of long displacement and relatively high velocity transients. Payloads, when subject to the rapid changes in velocity and direction, can respond by generating significant overturning moments, which must be restrained to avoid damage to testing equipment. Team has developed a number of systems, both single and multi-axis in response that provides the needed parameters with substantial moment restraint. By coupling Team’s long stroke HydraShakers with the hydrostatic T-Film tables, enormous moment restraint can be offered in an essentially friction free apparatus.

Bi-Axial Systems
Bi-Axial Systems —

The ability to generate excitations in either horizontal or vertical axes without purchasing two separate systems and/or repositioning the payload offers considerable cost savings and efficiencies in laboratory throughput. Team has realized Bi-Axial systems that combine our expertise in multi-axis technology with our hydrostatic bearing designs. Read More.

Head Expanders
Head Expanders —

Vertical excitation of a test object requires a mounting platform designed to be as stiff, yet light weight as possible; stiff to minimize influence on test results and light weight to conserve shaker force. This means the dynamic response of the mounting platform, or Head Expander must have the first mode outside the test band, or if within the test band, the response must be very well damped. Read More 

Horizontal Test System
Horizontal Test System —

As the recognized leader in high performance servo hydraulic vibration test systems, Team has considerable history developing and delivering both conventional and unique Horizontal Test Systems. Team’s solutions are typically based upon two proprietary products in Team's arsenal of vibration components, the HydraShaker and the T-Film Slip Table. Read More

HydraBall

Large Platform Systems —

Team’s core competency is custom system design utilizing best engineering practices and sophisticated modeling tools to ensure estimated performance targets are met. This focus has led to many firsts including the largest vibration test system ever installed, at NASA’s Plum Brook facility for subjecting full scale spacecraft ... Read More

Linear Actuators
Linear Actuators —

Team’s Linear Actuators, or HydraShakers, are a fundamental component in virtually every vibration test system delivered since the late 1950’s. Designed specifically for use in producing controllable vibration response, the HydraShaker is optimized for performance, fatigue rated and using hydrostatic bearing ...  Read More

MANTIS™
MANTIS™ —

The most common multi-axis test system in use today is called a MAST system, or Multi Axis Simulation Table. Very effective in reproducing measured road data, MAST systems are generally limited to fairly low frequencies, typically less than 50 Hz. And the actuator to table connection is generally a rod end bearing, prone to corrupting system response if not properly preloaded ...Read More

NEBS GR-63-CORE System
NEBS GR-63-CORE System —

Telecommunication systems play an integral role in the world’s economy and as such, must continue to operate in the event of an earthquake or when subjected to a variety of environment stresses. NEBS GR-63-CORE is a test standard originally developed by the Bell Laboratories ... Read More

Pad Bearings
Pad Bearings —

Developing and applying hydrostatic bearing and coupling technology is a core competency of Team Corporation. One product unique to Team’s vibration system set of components is the Pad Bearing, a fully hydrostatic single degree of control coupling. The combination of a planar and spherical hydrostatic surface permits a highly transmissible connection in compression ... Read More

Spherical Couplings
Spherical Couplings —

The alignment of a linear exciter to a moving table or test object, and maintaining a highly transmissible connection, is a challenge for vibration equipment designers and installation crews. Under stress, a table or test object may experience dynamic deformation which may place eccentric loading into the exciter shaft or armature ...  Read More

SSTS-600 & 1200 —

NAVSEA Ship Survivability guidelines mandate the shock testing of any component being placed into service. Anytime a change is made in a previously qualified component, a representative unit must be tested again. For any device using Commercial Off The Shelf (COTS) electronic components ... Read More

T-Film Slip Tables
T-Film Slip Tables —

An outstanding example of how correct application of hydrostatic linear bearing technology can provide sizeable advantages to horizontal test systems is the T-Film Slip Table. Team’s T-Film Slip Table designs use modular hydrostatic linear bearings, operating with only 600 psi hydraulic oil supply, vs. the 3,000 psi oil typically required by hydrostatic journal bearings. Read More

T8/V8 Linear Hydrostatic Bearings —

Defining a single line of motion while simultaneously restraining all other degrees of freedom is the function of any linear bearing. Team’s T8 & V8 Hydrostatic Linear Bearings were introduced more than 40 years ago to perform precisely that task and remain the undisputed top choice for accuracy, load carrying capacity and ruggedness.  Read More

Vertical Test Systems
