A prediction model of the shape of preform was established based on a fixed multi-nozzle test and development equipment of spray forming. The movement parameters of substrate was optimized according to the deposition behaviour of the droplets, and the growth process of deposit and the shapes of preform were simulated. Finally, the effecting mechanism of the atomizers with a tilt angle to the shape of preforms was studied by analyzing the simulation results.
Firstly, the modeling was simplified according...
