平面四杆机构在舰载垂直发射装置舱口盖系统中的应用分析
|
摘要
目的研究在舰载垂直发射装置舱口盖系统中设计平面四杆机构的方案的可行性与可靠性。方法提出舱口盖开盖系统设计方案,建立平面四杆机构开盖模型,进行理论分析与计算,建立ADAMS动力学仿真模型,对曲柄摇杆机构进行仿真分析,并与理论计算值进行对比。进行30～90kg负载试验,计算舱口盖开盖的角度和时间。结果舱口盖开盖解锁机构各构件的长度及电机的开盖扭矩应不小于569 N·m,转速应小于10 r/min。电机的开盖扭矩值应不小于509 N·m,复核复算结果基本一致。舱口盖开盖的角度应大于93°,开盖时间为2.8 s,满足要求。结论验证了方案的可行性,为其他垂直发射装置的舱口盖设计提供了工程经验。
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.
