Based on its line of Hydraulic Test Actuators, Moog’s Hydraulic Simulation Table is a six-legged hexapod with two equilateral triangular frames set one above the other, offset at 30°. Each apex of the top triangle is connected to the two apexes below it via the actuators with Hydrostatic Bearings.
The table gives users a frequency of response up to 100 Hz and can handle payloads up to 680kg (1,500 lbs). According to the company, auto makers and independent test houses can use this to replicate real-world road conditions that strain automobile components, such as axles, engines, interior and exterior assemblies, seats, steering column assemblies, cooling module systems, truck and tractor cabs, and After Treatment Systems (ATS) for heavy-duty diesel applications.
Exova, a global automotive testing provider, is using the simulation table. Steve Panter, operation manager, commented: “A lot of damage occurs within the range from 50 to 80 Hz when a company does testing analysis. With a lower performance simulation table, results are often filtered down to 40 Hz, so any damaging events beyond that point are not captured. The Moog Hydraulic Simulation Table allows those events to be included in the scope of testing, and broadens the value of the testing process.”
