The main subject of special winch for the middle of the production engineering simulation test system , dynamic design method to study the vibration problem in the course of their work . In the oil exploration , from the spray to the mechanical process of oil , mechanical oil production equipment , downhole tools , the job process method and supporting facilities required for the intermediate analog test . Therefore, the middle of the production engineering simulation test oil production has become an indispensable part of scientific research and promotion With the new lifting technique , operating tools , it will play an increasingly important role . Various stages of development in the field of artificial lift , slice mining , production logging and other aspects of testing means . The winch is an important part of the middle of the production engineering simulation test system , which bears as a starting operating under power and instruments of domination , the system one of the energy-consuming equipment , on the merits of its normal functioning and performance system security, reliability plays a decisive role . Therefore, the study of the winch dynamic design methods to improve the dynamic performance of great significance. In this paper, rotor dynamics theory and finite element theory simplify the winch drive system with a rigid disc , two elastic support , two rigid support typical rotor - bearing system , and stiffness matrix , mass matrix by explicit drivetrain represented by the equation of motion , the calculated natural frequency of the derived winch and dynamic response analysis winch main generating vibration during operation ; using direct derivation structure sensitivity analysis to determine the most sensitive to the structural design parameters , propose solutions programs, and use based on perturbation iterative theoretical modify the structure of the re - analysis method to quickly obtain the dynamic characteristics of the structure is modified ; using ANSYS and ADAMS software co-simulation to simulate actual operating conditions , compared to the functioning of the winch before and after optimization . The simulation results are consistent with the theoretical analysis , the dynamic design approach is reasonable and feasible . In this paper, the dynamic design method for the optimization of similar winch research play a certain reference .
