Design Of Bionic Robot Fish With Dielectric Elastomer

In recent years,with the development of smart materials,its application fields are more extensive.As one of electroactive polymers,dielectric EAP material has important research value in the field of smart materials.Dielectric EAP materials have the advantages of light weight,zero noise,high energy density ratio,large deformation,rapid response and good environmental adaptation,etc.,so they are also called "artificial muscles".In this paper,through the deformation principle of the dielectric EAP material,a dielectric EAP cylindrical driver is designed and manufactured.Using its output performance,a new type of flexible bionic robot fish is designed,which is more suitable for complex underwater environments.Based on the performance analysis of the dielectric EAP material and the cylindrical actuator,the spring specifications,the stretching ratio of the dielectric EAP film,the number of winding layers of the dielectric EAP film,the coating area ratio of the flexible electrode,and the spring pre-compression rate Other influencing factors were experimentally explored,analyzed and summarized,so as to determine the production parameters of the drive,and summarized the destruction mode of the drive.The dielectric EAP film stretching device is designed and manufactured to make it more convenient and efficient to use.Analyze the problems existing in the structural design and manufacturing process of the cylindrical drive,and improve and optimize it.At the same time,combined with the manufacturing parameters determined by the experiment,the manufacturing process of the dielectric EAP cylindrical driver is described in detail,and the experimental test is carried out.In order to further analyze the force situation of the dielectric EAP cylindrical driver,a simulation analysis of the simplified driver model was carried out to verify the experimental results.The control system of the drive unit is designed,and each module is analyzed and explained in detail.At the same time,a new type of flexible bionic robot fish was designed on the basis of the previous,and the structural design and manufacturing process were described in detail.
