【摘要】：舱门是舱门训练器结构中的一个重要部件,主要功能是使其能按照预定的轨迹运行。舱门的理想运动轨迹与实际运动轨迹的偏差程度,直接反映了舱门训练器的设计质量。本文借助Pro/Engineer软件的功能模块,建立起了舱门训练器的三维模型,并对其进行运动轨迹与结构力学分析,为舱门训练器研制过程中的构件安装、调试、检验等操作提供帮助和参考。主要研究内容如下:建立了舱门训练器的3D模型,并根据舱门的特点与构件的复杂程度,简化舱门模型。按照构件的连接方式,为运动机构添加正确的约束。通过分析止动滚轮的位移、速度,获得其对应的时程曲线图,分析并验证了舱门开启过程中的运动特性。在分析舱门运动轨迹的基础之上,建立舱门训练器中相关机构的灵敏度模型。选取舱门四连杆平移机构与内手柄机构为例,以舱门运动轨迹为目标函数,分别建立了关于四连杆平移机构与内手柄机构的灵敏度分析模型,通过求解器求解,得到影响舱门运动轨迹和止动滚轮运动轨迹的主要参数。在灵敏度分析基础上,针对所确定的主要参数进行尺寸优化设计,获得优化后各机构的位置曲线图,通过对比优化前后的位置曲线与和设计曲线控制点,实现对舱门机械结构的修正。其次,针对内手柄进行了力学结构分析,验证了在模拟载荷下内手柄的结构可靠性。
[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.
