An alternative propulsion or motive force for the riders of water features based on generated waves. A wave generator may be used to propel individuals or vessels within a chute for recreation or transportation. In one form, a pool or container having a body of water is configured to support an artificial wave generator which uses compressed gas to discharge water and generate a wave-like motion within a body of water. A source of make-up fluid is configured to mitigate internal low pressure conditions caused by the water discharge to enable effective wave generation with reduced quantities of compressed air. Portions of the waves generated in a pool may be captured in a variety of ways by chutes for stand-alone rides or for portions of chutes in water slides.

The invention belongs to the technical field of anti-seismic safety analysis and evaluation of nuclear power equipment engineering, and relates to a multi-damping artificial wave fitting method for constructing a multi-parameterized time domain adjustment curve. According to the narrow-band time history construction method, the narrow-band time history has narrow-band characteristics in a time domain and a frequency domain, the ringing effect caused by Fourier transform is avoided, and the new narrow-band time history is called as a standard input time history; the artificial wave is roughly adjusted in a mode of separately superposing each damping ratio of each frequency control point with the standard input time history; then, a frequency control point with the maximum absolute deviationis searched; the optimal weight combination of the standard input time history of each damping ratio at the frequency is searched by using a simulated annealing algorithm so as to simultaneously superpose the standard input time history of multiple damping ratios, thereby controlling the influence of the superposed time history on the response spectrum in the time domain adjustment process and further improving the fitting precision of all damping ratio response spectrums at the frequency; a frequency control point with the maximum relative deviation is searched, and circularly adjusting is performed in the same way; and finally, the artificial wave is adjusted in the post-processing module, so that the artificial wave meets the standard requirement, and the fitting precision is further improved. According to the method, the multi-damping artificial wave fitting problem formed by the frequency and the damping ratio is subjected to dimensionality reduction processing, the problem is simplified into the one-dimensional problem only needing to pay attention to the frequency, and the artificial seismic wave of the high-precision fitting multi-damping nuclear power design spectrum canbe generated.
