| In this paper,The main research objects of squid are freshwater fish.The main research objects of squid are silver carp and prawn.,with reference to the research results of fish body orientation at home and abroad,and the technique of directional alignment of materials using vibration in agricultural machinery,The way of the way of the road,and the method of using the gradient slide to orient the abdomen of the fish,and using the Adams analysis software to simulate the dynamics of the designed equipment,the simulation results are used to verify the scientific and feasible method.Sex.The paper studies the mass distribution of fish body.According to the analysis,the quality of fish body is mainly distributed on the back and head of the fish.Therefore,during the vibration process,the fish body will show the head down and the tail upward.Unification direction.In the subsequent gradual slide,the fish body will show the direction of the back up and the abdomen facing downward under the action of the vibration force.After designing the 3D model of the device,it is imported into the Adams software for dynamic simulation,and the data is recorded,and the initial point of the fish body is fed to the spiral vibration table,And the vibration frequency of the vibrating machine,the excitation force,the friction factor of the slide as the initial factor of the simulation,the fish body orientation success rate and the time-consuming process of the orientation process as the simulation indicators,through the simulation results The head-to-tail orientation success rate of the fish body can reach 96.83%,and the orientation time is completed within 5.13s;the ventral back orientation success rate can reach 97.23%,and the orientation time is completed within 3.83 s.During the simulation,all the initial factors of the simulation are found to have a significant impact on the final simulation results.At the same time,through the simulation animation results,it can be seen that the method of using the spiral vibration chute to orient the head and tail of the fish body is feasible.The designed 3D model was imported into Adams for dynamic simulation.It was verified that the head and tail orientation of the fish body can be realized by friction.The gradient slide can be used to make the fish body reverse the torque,and the fish body can be turned over until the fish The back of the body is facing up and the abdomen is facing down.It also traces the displacement,velocity and acceleration of the centroid when the fish body is on the vibrating table.It is found that its motion is mainly divided into two parts,that is,there are two constant accelerations,which are consistent with the setting of the two processes,that is,the head and tail are first Orientation,and then ventral orientation.Finally,the method of image recognition is used to realize the orientation of fish body,and the corresponding program is programmed by Matlab for simulation operation.The working sequence of positioning is analyzed,that is,the fish body is binarized first,then denoised,the fish body position is located and the parts of the fish body are segmented and positioned.Mathematical models of various programs were constructed,and the implementation steps of various types of positioning were established. |
