【摘要】：艙門是艙門訓(xùn)練器結(jié)構(gòu)中的一個(gè)重要部件,主要功能是使其能按照預(yù)定的軌跡運(yùn)行。艙門的理想運(yùn)動(dòng)軌跡與實(shí)際運(yùn)動(dòng)軌跡的偏差程度,直接反映了艙門訓(xùn)練器的設(shè)計(jì)質(zhì)量。本文借助Pro/Engineer軟件的功能模塊,建立起了艙門訓(xùn)練器的三維模型,并對(duì)其進(jìn)行運(yùn)動(dòng)軌跡與結(jié)構(gòu)力學(xué)分析,為艙門訓(xùn)練器研制過程中的構(gòu)件安裝、調(diào)試、檢驗(yàn)等操作提供幫助和參考。主要研究?jī)?nèi)容如下:建立了艙門訓(xùn)練器的3D模型,并根據(jù)艙門的特點(diǎn)與構(gòu)件的復(fù)雜程度,簡(jiǎn)化艙門模型。按照構(gòu)件的連接方式,為運(yùn)動(dòng)機(jī)構(gòu)添加正確的約束。通過分析止動(dòng)滾輪的位移、速度,獲得其對(duì)應(yīng)的時(shí)程曲線圖,分析并驗(yàn)證了艙門開啟過程中的運(yùn)動(dòng)特性。在分析艙門運(yùn)動(dòng)軌跡的基礎(chǔ)之上,建立艙門訓(xùn)練器中相關(guān)機(jī)構(gòu)的靈敏度模型。選取艙門四連桿平移機(jī)構(gòu)與內(nèi)手柄機(jī)構(gòu)為例,以艙門運(yùn)動(dòng)軌跡為目標(biāo)函數(shù),分別建立了關(guān)于四連桿平移機(jī)構(gòu)與內(nèi)手柄機(jī)構(gòu)的靈敏度分析模型,通過求解器求解,得到影響艙門運(yùn)動(dòng)軌跡和止動(dòng)滾輪運(yùn)動(dòng)軌跡的主要參數(shù)。在靈敏度分析基礎(chǔ)上,針對(duì)所確定的主要參數(shù)進(jìn)行尺寸優(yōu)化設(shè)計(jì),獲得優(yōu)化后各機(jī)構(gòu)的位置曲線圖,通過對(duì)比優(yōu)化前后的位置曲線與和設(shè)計(jì)曲線控制點(diǎn),實(shí)現(xiàn)對(duì)艙門機(jī)械結(jié)構(gòu)的修正。其次,針對(duì)內(nèi)手柄進(jìn)行了力學(xué)結(jié)構(gòu)分析,驗(yàn)證了在模擬載荷下內(nèi)手柄的結(jié)構(gòu)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.
