Abstract

This paper describes a process for optimizing the design of the landing slope of the Zao jumping hill. The features of the landing slope that we considered were the construction fee, the safety of the jumpers on landing, the length of the flight distance such that it makes it an interesting spectacle, and the difficulty for unskilled jumpers. We regard these features as objective functions. The findings can be summarized as follows: it is possible to control the four objective functions by changing the profile of the landing slope; the safety on landing is almost equivalent to the difficulty for unskilled jumpers; there is a trade-off between the length of the flight distance and the safety on landing and the difficulty for unskilled jumpers; the construction fee is influenced by the horizontal distance between the edge of the take-off table and the K-point; and the safety on landing, the flight distance and the difficulty for unskilled jumpers are influenced by the ratio of the height difference and the horizontal distance between the edge of the take-off table and the K-point.
