Full Exhaust System Testing utilizing MAST Tables
Dual Mast Table Exhaust Test
Testing the complete exhaust system using MAST tables allows an OEM to expose the system to a life-time of usage simulated in a laboratory environment over the course of just a few weeks. This type of testing typically starts with the instrumentation of the exhaust system and vehicle with accelerometers, thermocouples and strain gages. Somat E-Dac acquisition systems are used to collect the road load data while the vehicle is driven over proving ground events. Data analysis and editing is done with nCode Glyph works analysis software. This allows the test time to be reduced while retaining the damage that the exhaust system would see for the specified durability schedule.
MGA can accept many formats of CAD data from the customer which is then used to design the test fixtures. Fixtures are built and certified to provide the mounting locations for the engine and the body side hangers.
Drive files are created using RPC Proä to replicate the exhaust system responses from the test track. Propane burners to introduce hot air at the exhaust manifold(s) to replicate the thermal environment of the exhaust system. The thermal inputs can range from a steady state temperature to a temperature profile based on customer requirements.
MGA has two dual MAST systems available with 6’ x 8’ tables and 11 Kip 6” stroke actuators for the vibration portion of the test and four 1 Million BTU burners for the thermal inputs.
