The automotive marketplace has been a significant driver of vibration test equipment development. The need to improve reliability and functionality of entire vehicles, as well as major sub-assemblies such as the instrument panel or seating, has led to the creation of multi-axis test systems capable of accurately reproducing recorded road data, torsional systems to determine fatigue characteristics of axle and crankshaft assemblies and systems that emulate operating engine performance in the test lab.

4-Posters —

Automotive testing of full vehicles has been proven to be an excellent means of improving product quality and customer satisfaction. The system of choice is a 4-Poster, where an independent actuator is used under each vehicle wheel to input the desired vertical excitation phased to replicate severe road conditions.  Read More

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


To reproduce the full spectrum of field environments by simultaneous excitation of all degrees of freedom is widely recognized as the ideal means to subject any test object to realistic stress accumulation. Team’s CUBETM is the first system to accurately produce controllable excitation up to 500 Hz in all DoF simultaneously, and remains the only system with this capability developed ... Read More

Engine Simulator
Engine Simulator —

Internal combustion engines generate torsional vibrations in the crankshaft that are transmitted throughout ancillary engine accessories such as the crankshaft damper, and belt driven equipment on the front end of the engine. Team has developed the 900 series of Engine Simulators ...  Read More

Engine Valve Actuator
Engine Valve Actuator —

The increasingly stringent Corporate Average Fuel Economy (CAFE) standards and tail pipe emission limitations are drivers for improving the performance of internal combustion engines. Improvements in modulating the intake and exhaust valve performance offer an avenue to assist in meeting these requirements. Read More

HydraBall —

The connection between a linear actuator and an articulating table is perhaps the most critical design challenge in any vibration system development. The connection must be highly transmissible, free of backlash and able to carry high forces through angular vectors. Read More


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 ...  Read More

Pitch Table
Pitch Table —

Designed to meet the requirements of a specific Ford Motor Company seat testing standard, Team’s Pitch Table combines both vertical and pitch motions using a single HydraShaker exciter. The pivots on the seat mounting table, permitting the rotational motions needed to create pitch, are Team double spherical hydrostatic couplings. Read More

Rotary Actuators
Rotary Actuators —

Producing oscillating rotational forces on a test object, for example an axle shaft, can be accomplished by using a linear actuator and an eccentric connecting shaft. However, the most efficient means is to apply the required rotational force directly to the hub through the use of a Rotary Actuator. 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

Hydrostatic Spherical Couplings
Hydrostatic 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

T8/V8 Linear Hydrostatic Bearings
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 ... Read More

TENSOR™ 900 & 18kN
TENSOR™ 900 & 18kN —

The TENSOR™ represents state-of-the-art advancement in multi-axis testing capability. Using 12 proprietary electrodynamic shakers to drive a single table, each TENSOR™ model can precisely control the amplitude and phase of the table response in all degrees of freedom through 2 kHz.  Read More

Transmission Simulator
Transmission Simulator —

Team's core competency is to develop unique test systems to address vexing reliability problems of our customers. The Transmission Simulator is an example of this custom engineering approach to problem solving. Automatic transmissions must operate in a relatively severe environment, subjected internally to rapid fluctuations in oil pressure accompanied by intermittent pressure spikes. Read More
