【摘要】：本文設(shè)計的救援訓練模擬器用于在陸上實驗室中模擬訓練救生人員在惡劣海況條件下進行的直升機懸停救助任務(wù)。相對于實際訓練,它具有安全高效,節(jié)省成本等優(yōu)點,必將成為救援訓練的重要方式之一。目前,我國救助訓練主要還是在實際環(huán)境中的訓練,為保證安全,還難以開展惡劣海況下的訓練,大連海事大學根據(jù)惡劣海況下直升機懸停救助的特點,提出建立由天車平移系統(tǒng)、電動六自由度平臺、機艙-絞車、模擬海上救助環(huán)境等構(gòu)成的直升機懸停救助模擬系統(tǒng),可以代替惡劣海況下直升機懸停救助的絕大部分任務(wù)。本論文著重針對直升機救援訓練模擬艙的結(jié)構(gòu)設(shè)計與動力學分析進行研究,根據(jù)總體要求設(shè)計出模擬艙的結(jié)構(gòu)并進行校核,通過模擬真實救援動作進行動力學分析,尋找出極限工況并對其進一步做有限元分析,從而確保模擬艙在運動中的安全性。首先,現(xiàn)場采集直升機在救援訓練時的位姿數(shù)據(jù),通過反解數(shù)據(jù)等方法獲得模擬艙的運動位移。根據(jù)救生員訓練大綱及實際情況提出了模擬艙結(jié)構(gòu)設(shè)計的特點與品質(zhì)要求。最終確定了模擬艙結(jié)構(gòu)設(shè)計的總體要求及參數(shù)。其次,根據(jù)所提出的要求進行設(shè)計。根據(jù)設(shè)計的總體要求與實際情況,設(shè)計了模擬艙骨架及模擬艙地板、蒙皮、連接橫梁、絞車連接臂等附件。在滿載荷的情況下,對所設(shè)計的部件進行了有限元分析,從而確定了模擬艙結(jié)構(gòu)的材料,保證了艙體的穩(wěn)定性與安全性。最后,進行動力學分析及極限工況的有限元分析。建立了動力學仿真模型及有限元仿真模型。通過輸入直升機真實救援時動作位姿數(shù)據(jù),獲得了模擬艙的實時受力。在艙體受到最大受力及加速度的情況下,進行有限元仿真與分析。分析結(jié)果表明：本文簡化后建立的模型與實際結(jié)構(gòu)基本相符,所做的仿真分析真實的反映了救助直升機訓練模擬艙機械系統(tǒng)的特性,驗證了救助模擬艙滿足靜態(tài)與動態(tài)救援訓練的強度要求和安全性要求。
[Abstract]:The rescue training simulator designed in this paper is used to simulate the rescue mission of helicopter hovering under the bad sea condition in the land laboratory. Compared with the actual training, it is safe and efficient. Cost saving and other advantages will become one of the important ways of rescue training. At present, rescue training in China is mainly in the actual environment training, in order to ensure safety, it is difficult to carry out training in bad sea conditions. According to the characteristics of helicopter hovering and rescue in bad sea conditions, Dalian Maritime University puts forward the establishment of crane translation system, electric six degrees of freedom platform and cabin winch. The helicopter hovering rescue simulation system which simulates the sea rescue environment and so on. This paper focuses on the structural design and dynamic analysis of helicopter rescue training simulation module. According to the overall requirements, the structure of the simulation module is designed and checked. By simulating the real rescue operation, the dynamic analysis is carried out to find out the limit conditions and do the finite element analysis. In order to ensure the safety of the simulation module in the movement. Firstly, the position and posture data of the helicopter in rescue training are collected on the spot. The movement displacement of the simulated cabin is obtained by inverse solution data. According to the training outline and the actual situation of the lifeguard, the characteristics and quality requirements of the structural design of the simulated cabin are put forward. Finally, the overall requirements of the structural design of the simulated cabin are determined. And parameters. Second. According to the requirements of the design, according to the overall requirements and the actual situation of the design, design the simulated cabin skeleton and the simulated cabin floor, skin, connecting beam, winch connection arm and other accessories. Under the full load condition. The finite element analysis of the designed components is carried out to determine the material of the simulated cabin structure and to ensure the stability and safety of the cabin. Finally. The dynamic analysis and finite element analysis of the limit condition are carried out. The dynamic simulation model and the finite element simulation model are established. In the case of the maximum force and acceleration of the cabin, the finite element simulation and analysis are carried out. The analysis results show that the simplified model is basically consistent with the actual structure. The simulation results reflect the characteristics of the mechanical system of the rescue helicopter training simulation module, and verify that the rescue simulation module meets the strength and safety requirements of the static and dynamic rescue training.
