According to the insufficient force analysis of the cable in the process of winch retraction, especially the insufficient research on the flexible cable retraction process such as the UHMWPE cable, the dynamic simulation analysis of the retraction process of the parallel grooved multi-layer drum and UHMWPE cable cable is carried out by using the virtual prototype software ADAMS. The simulation model of the cable is created by using the macro command program, and the virtual prototype model of the cable drum is completed, and the force changes of the cable under different rotating speeds are simulated.The simulation results show that the contact force between the cable and the double winding drum can be quickly stable under the specific load, and with the increase of the rotating speed, the maximum value of the tension change of the cable increases, but it is finally stable at a fixed value. The results can provide some reference for structural strength calculation of cable storage drum, selection of high molecular polyethylene cable and dynamic analysis of cable arranger under load.

Abstract Due to the complex loads on a bionic robotic fish operating underwater, the reliability of its working mechanism has an important effect on its overall performance. By establishing a virtual prototype model for the rigid–flexible coupling of a bionic robotic fish, we obtained the instantaneous load on the caudal fin of the robotic fish based on the flapping-wing propulsion theory with MATLAB. A rigid–flexible coupled virtual prototype model for the caudal fin drive as a flexible member of the bionic robotic fish was established, and dynamic simulations were conducted on the model. The simulations revealed the weak links in the drive shaft and established a damage level indicator and fatigue reliability analysis method based on damage theory. The behavior of fatigue reliability for different stress cycles was established, and a dynamic reliability design method with great engineering application value was proposed for virtual prototypes of rigid–flexible coupled underwater bionic robots by combining the virtual prototype technology of rigid–flexible coupling with the theory of flapping wing propulsion and the theory of random load fatigue reliability.
