Solution for modelling and plumbic block locating in sinking artificial fish-simulated bait

The effect of artificial fish-simulated bait in sea fishing is obvious. However, the manufacture of artificial fish-simulated bait still does not implement automation design. According to the need of customers, the request of artificial fish-simulated bait´s external shape is special to make the irregular shape of artificial fish-simulated bait. In order to design the shape of artificial fish-simulated bait fast and intuitively for customers, this paper uses computer software design technology to build the mathematical model of artificial fish-simulated bait´s, by changing the parameters of model to get artificial fish-simulated bait which has different kinds of shape to supply the demand of customers, giving intuitive design effect for customers visually. Artificial fish-simulated bait is divided into two types, One is sinking type, the other is floating type. The first one needs plumbic block to be filled, but the second one does not need. By analyzing the force of sinking artificial fish-simulated bait in seawater, we can get parameters which can influence sinking of artificial fish-simulated bait, then calculate these parameters by using physical and mathematical methods to gain the locating algorithm of the plumbic block.
