Abstract

Len Lye (1901-1980) was an artist who wanted to build kinetic sculptures at a monumental size however he was constrained by the availability of resources and technology. This paper examines the structural design of a vertical cantilever beam which is a key element in the monumental version of Lye’s ‘Flaming Harmonic’. In ‘Flaming Harmonic’ the vertical cantilever vibrates at resonant bending and whirling frequencies due to a reciprocating harmonic ground movement which is provided by a mechanical drive. Lye produced a 1.3m tall model of a similar work called ‘Harmonic’. Design rules developed in this paper show that ‘Flaming Harmonic’ can be produced at a height of 14m. Similarity between ‘Harmonic’ and ‘Flaming Harmonic’ ensures that while the artwork is produced posthumously, artistic integrity for the larger work will be preserved. The vibratory mode shapes and corresponding stresses are established for ‘fixed’ and ‘pivot’ clamp designs. It is shown that while a slightly different vibrating shape is achieved using each method the ‘pivot’ clamp design results in a lower bending stress and hence a longer life for the vertical cantilever.
