New MTS technology provides control of critical rider loads and chassis motion to provide for more accurate small-vehicle structural testing.

 

Historically, representing the physical influences of the rider during motorcycle and ATV structural testing has been limited to “passive” systems that mass-load the chassis, but cannot replicate the dynamic forces introduced by the rider at the handlebars, seat and foot-pegs. This influence gets magnified in harsh off-road riding environments, as riders must continuously couple and decouple their masses to control the movement of their vehicles.

Dave Fricke, senior staff engineer at MTS, discusses new active chassis control technology for small vehicle simulation, which is capable of reproducing highly accurate dynamic chassis loads caused by the rider, while simultaneously positioning the chassis for a full range of riding conditions, including taking jumps.

Materials Testing Feature
As Airbus, Boeing, GE and other original equipment manufacturers (OEMs) in the aerospace industry make it mandatory for material suppliers to pass cooperative Nadcap audits, tier suppliers are compelled to produce evidence of compliance to physical test standards and methodologies required by OEMs. In turn, a heightened focus has been placed on the maintainability and repeatability of material test machines to remain tightly aligned within specified tolerances.

Jim Hennen, MTS product manager for aftermarket services, discusses why precision-engineered load frames and grip assemblies are essential to ensuring compliance with the industry standards for materials testing.
