Simulation research of heave compensation winch based on virtual prototype

Heave compensation system is one of the necessary equipment to ensure the normal operation of ultra-depth floating drilling. Based on direct drive volume control and hydraulic transformer energy-recycle technology, a new type of multifunctional energy-saving heave compensation winch(HCW), which has the functions of drilling winch, heave compensation and energy-recycle, is introduced. The mechanical structure design of HCW's actuator is finished with Solidworks software. The hydraulic simulation model of HCW's direct drive volume control power mechanism is established by using AMESim software. The HCW's virtual prototype is established by using the co-simulation method of AMESim and ADMAS software. The problem of contact collision modeling for meshing gear is solved. The simulation is carried out based on established virtual prototype. The simulation results show that the virtual prototype established is correct. The comparison of simulation result and theoretical calculation value of gear meshing force shows that the method of contact collision modeling for meshing gear is feasible. The results are helpful to study HCW's performance in all its aspects.
