Rotary fatigue tester.This independent testing facility for tires, wheels and related automotive components offers a rotary fatigue test machine. This test machine performs dynamic cornering fatigue tests on wheels per SAE, SFI SFI Sustainable Forestry Initiative (forest certification program of AF&PA) SFI Santa Fe Institute (scientific research in Santa Fe, New Mexico) SFI Science Foundation Ireland SFI Six Figure Income and JASO JASO Japan America Societies specifications. The rotary fatigue test machine is designed to impart a constant, rotating, bending moment A bending moment exists in a structural element when a moment or torque is applied to the element so that the element bends. Moments and torques are measured as a force multiplied by a distance so they have units such as newton.metres (N.m) and foot.pounds (ft.lb). to the wheel through applying a load of 90[degrees] to the wheel mounting face. This simulates the forces applied to the wheel when cornering during rotation. Wheel failures generated through this testing include both the inability to hold a load and/or a visually-detected fatigue crack penetrating through a section of the wheel. The rotary fatigue machine features a hydraulic loading via a self-contained hydraulic power unit. An airbag shaft lift system allows for wheel mounting and dismounting, with the airbag dropping out of the way while the wheel is running. A digital display of measured parameters clearly exhibits testing data, in English or metric, on applied force, speed, deflection, elapsed time e·lapsed time n. The measured duration of an event. Noun 1. elapsed time - the time that elapses while some event is occurring and elapsed e·lapse intr.v. e·lapsed, e·laps·ing, e·laps·es To slip by; pass: Weeks elapsed before we could start renovating. n. revolutions, according to the manufacturer.
