| Abstract: |
| Objective To research the feasibility and reliability of scheme for designing plane four poles mechanism for hatch system of ship vertical launcher. Methods The hatch opening system scheme was proposed according to the opening angle and time index in ship vertical launcher. The four poles mechanism model was built for theoretical analysis and calculation. An ADAMS dynamic model was built to simulate the crank and rocker mechanism and compare with the calculated value. The 30-90 kg load test was carried out to calculate the angle and time of hatch opening. Results The hatch torque should not be less than 569 N•m, and speed should be less than 10 r/min. The cover opening torque of the motor should not be less than 509 N•m. The review result was basically consistent. The opening angel should be larger than 93° and the opening time should be 2.8 s. The requirements were met. Conclusion The scheme feasibility is verified. It provides engineering experiences for design of hatch for vertical launcher. |
