Multi-Axis Simulation Tables (MAST)
MGA utilizes both MTS and MGA Multi-Axis Simulation Tables (MAST). All MAST tables are controlled by the latest MTS FlexTest controllers and take advantage of the sophisticated RPC Pro and MPT Control Software. With our latest lab expansion, MGA now operates ten (10) MAST tables in Michigan with additional tables in New York and Wisconsin.

Component Simulation
Using MTS servo hydraulic controllers such as the FlexTest 200, MGA is able to conduct simulation testing on full systems and components with direct inputs to the sample. When basic fatigue testing can not reproduce the effects of a complicated system, it is best to apply real road simulations directly. MGA can provide as many inputs as necessary to create complex rigs that accurately simulate real world conditions.
Road Load Simulation
The most common type of MAST testing is Road Load Simulation in which data that is collected from a vehicle is matched and used to simulate the life of various components in that vehicle. Road Load Data (RLD) is acceleration (or strain) data that is collected from different road surfaces on a test track. This data is either collected at the Supplier/OEM’s facility, or at the MGA-Wisconsin facility. MGA has experienced staff in place to analyze and edit this data to facilitate efficiency in our customer’s tests. Our equipment is used to match multiple channels of acceleration data to accurately expose the test part to a (6) degree-of-freedom durability schedule.

Full Vehicle Simulation (Four-Post)
A Hydraulic Four-Post system is a collection of (4) hydraulic pedestal actuators positioned such that the (4) wheels of a vehicle can sit on the wheel carriages attached to the actuators. This system can be used to evaluate the vehicle body structure, frame, chassis, internal components, or interior squeaks and rattles. The four-post system is rated for passenger cars or light-duty trucks.
System Level Vibration Durability (MAST or Dual MAST)
Vibration testing can also be applied to system level designs such as full exhaust systems, exhaust systems for large trucks, full cockpits (instrument panel and center console systems), suspension systems, etc. Often times for the afore-mentioned exhaust tests, the vibration will run in conjunction with hot gas simulation. We have also performed full exhaust tests in which the entire exhaust system spans (2) MAST systems working simultaneously to match acceleration and strain data.
