CETR HDI Load/Unload options can accommodate either CETR or any customer ramps.
During the tests, dynamics of load/unload is measured with friction, gram-load and AE sensors, the resultant surface degradation is measured in-situ using our TAA and TA-Mapping options.
4 degree-of-freedom load/unload for production testing
The production 4-degree-of-freedom load/unload allows ramp positioning and adjustment independently in 4 directions (4-degrees of freedom). Laser cut radial, angular and diameter scales ensure accurate positioning along three linear axis. A micrometer is used for vertical positioning (the fourth axis). A locking stop is available to ensure rapid loading and repeatability for consistent production testing. This option allows for fast, repeatable, and consistent ramp adjustment and positioning.
4 degree-of-freedom load/unload for R&D studies
The 4 degree-of-freedom load/unload allows ramp positioning and adjustment independently in 3 directions and around 1 vertical rotation axis (4 degrees of freedom). Linear slides with micrometers are used for positioning along three linear axes. Each slide has a screw for locking in any position. The position of the ramp is determined from the micrometer's reading. The resolution of all the micrometers is .001”, their travel is .25”. A rotary stage with worm gear and a 0.5° resolution scale is used for angular adjustment. Due to self-locking of the worm gear, there is no locking screw on the rotary stage.
This option allows for fine, fast and consistent ramp positioning. After positioning, all the slides are secured with thumb screws. |
