The sculptures of the Swiss artist Jean Tinguely are rusty, steel constructions that generate a high-pitched squeal during motion. While the sculptures are visually remarkable, an essential component of the work is the noise. Unfortunately, the sliding parts have been wearing out over the years, and as a result the amount of time that the sculptures can be in motion has been reduced significantly. In order to protect these works of art, we would like to develop a system that protects the sliding parts against wear but, at the same time, allows the high-pitched squeal to be maintained. In this presentation, the noise emissions will be described and possible solution strategies will be discussed.
