<p class="MsoNormal"><span style="font-family:"Times New Roman","serif"">Using stroboscopic X-ray diffraction to measure dynamic strain in moving machine parts is relatively well established. Our recent successful measurement of dynamic contact strain in the
outer raceway of a ball bearing at Diamond Light Source is an example of applying the technique. Most large engineering components are too thick to be measured using X-rays, so neutron diffraction is a more suitable technique in such components. The project
involves development of hardware and software required to carry out such experiments at UK’s Neutron Source, ISIS. An example component where neutron diffraction could help is the shaft bearing of a large wind turbine. The load path, from the blades through
the gearbox to the shaft, is complex and highly transient. Simple measurements of torque on the rotor shafts cannot be used to determine the load history of the bearings. Stroboscopic measurements of strain with neutrons will provide a new tool for studying
machine components, providing valuable knowledge which can be used for life prediction models and the development of complementary condition monitoring methods.
