Abstract

The SKA MPI Demonstrator was built at the SARAO site in the Meerkat National Park in South Africa. It provided valuable experience for the MeerKAT Extension project. The commissioning of the SKA MPI Demonstrator was accompanied by the collection of a large amount of wind data acquired from the a nearby weather station. Combined with the servo-relevant measurements such as torques, motor rates, position encoder readouts, and temperatures from different locations, it provided valuable input for characterizing the influence of wind loads on the structure. We present the results of the dynamic analysis of the data collected over several months: wind torque coefficients, as well as supporting friction curves and demonstrate how this information is used in the dynamic simulations
