【摘要】：艙門是艙門訓練器結構中的一個重要部件,主要功能是使其能按照預定的軌跡運行。艙門的理想運動軌跡與實際運動軌跡的偏差程度,直接反映了艙門訓練器的設計質量。本文借助Pro/Engineer軟件的功能模塊,建立起了艙門訓練器的三維模型,并對其進行運動軌跡與結構力學分析,為艙門訓練器研制過程中的構件安裝、調試、檢驗等操作提供幫助和參考。主要研究內容如下:建立了艙門訓練器的3D模型,并根據(jù)艙門的特點與構件的復雜程度,簡化艙門模型。按照構件的連接方式,為運動機構添加正確的約束。通過分析止動滾輪的位移、速度,獲得其對應的時程曲線圖,分析并驗證了艙門開啟過程中的運動特性。在分析艙門運動軌跡的基礎之上,建立艙門訓練器中相關機構的靈敏度模型。選取艙門四連桿平移機構與內手柄機構為例,以艙門運動軌跡為目標函數(shù),分別建立了關于四連桿平移機構與內手柄機構的靈敏度分析模型,通過求解器求解,得到影響艙門運動軌跡和止動滾輪運動軌跡的主要參數(shù)。在靈敏度分析基礎上,針對所確定的主要參數(shù)進行尺寸優(yōu)化設計,獲得優(yōu)化后各機構的位置曲線圖,通過對比優(yōu)化前后的位置曲線與和設計曲線控制點,實現(xiàn)對艙門機械結構的修正。其次,針對內手柄進行了力學結構分析,驗證了在模擬載荷下內手柄的結構可靠性。
[Abstract]:The door is an important part of training in the door structure, the main function is to track scheduled. According to the deviation degree of ideal trajectory and actual trajectory of the door, the door directly reflects the quality of design training device. In this paper the function module with the help of Pro/Engineer software, established a three-dimensional model of the door training device, and analyzing the trajectory of the structure and the mechanical installation and debugging for the component door training device in the process of development, to provide help and reference check operation. The main research contents are as follows: to establish the 3D model of the door training device, and according to the characteristics and complexity of component door, door model is simplified. In accordance with the connection component, add the correct constraints for motion mechanism. Through the analysis of stopping wheel displacement, velocity, time history curve to obtain the corresponding analysis, and verify the door open The motion characteristics of the process. Based on the analysis of the hatch trajectory, a sensitivity model of relevant institutions in training. From the door door four connecting rod mechanism and handle mechanism in translation as an example, to hatch trajectory as the objective function, respectively analysis model was established on the four linkage mechanism and the sensitivity of translation within the handle mechanism. Through the solver, influence the trajectory of door and check the main parameters of the rolling wheel trajectory. In the sensitivity analysis based on the main parameters determined by size optimization, position curve of the mechanism was optimized by position curve comparison before and after optimization and design of curve control points to modify the door of the mechanical structure. Secondly, according to the internal handle for the mechanical structure analysis, verified the structural reliability under the simulated load in the handle.
