Research of Interactive Blades Vibration Adjustment Simulation 

摘要:

为解决目前机务维修培训中存在的物理样机难以满足需求的问题,以实际机务维修工作中旋翼振动调整方法为参考,提出在虚拟维修训练系统的基础上实现受训人员对虚拟样机旋翼桨叶进行振动调整仿真操作,以期达到训练目的；根据非沉浸式虚拟维修训练系统的特点设计交互仿真操作逻辑,确定仿真操作步骤,分析座舱振动可视化表示方法,专用虚拟样机的构建方法以及虚拟仪器的实现方式和数据组织结构形式,并将该仿真实验以模块化形式添加到虚拟维修训练系统中,满足拆装条件下对虚拟样机的交互操作需求；最后以欧直松鼠直升机虚拟样机旋翼振动调整方法为例验证该操作仿真逻辑的可用性。

Abstract:

In order to solve the problems that physical prototype can’t satisfy the current engineering maintenance training. Based on the method of blades vibration adjustment for the practical work reference. Put forward that trainees do the operation of blades vibration adjustment with virtual prototype in Virtual Maintenance Training System. Design the interactive simulation logic, determine the steps, Analysis the visual representation method of cockpit vibration and the method of virtual prototype build based on the system’s feature. It also proposed the method of the virtual instrument’s implementation and the data organization form. Then add the experiment to VMTS in a modular form in order to satisfy the demands of interactive. Finally, make the AS350 helicopter virtual prototype’s blades vibration adjustment as an example to verify the availability of the simulation logic.
