摘要
针对传统的消耗规律确定方法很难准确地预测舰炮机械件的消耗量的问题,提出基于虚拟样机的机械件消耗规律确定方法。以舰炮典型机械机构方向传动系统为例,采用FTA、FMECA方法得到该机械机构的关重件,采用Virtual.Lab Motion仿真软件构建了方向传动系统仿真模型,对齿轮故障进行仿真验证;通过建立疲劳可靠性寿命预测流程与模型,得到不同可靠度下的第三级齿轮疲劳可靠性寿命;在对核对表法修正的基础上,建立机械件年消耗量解析模型,得到了方向传动系统年平均消耗量。应用表明,该方法可较准确获得装备机械件年消耗量。
Traditional consumption law confirmation method is hard to accurately forecast shipborn gun mechanical spares consumption. Put forward mechanical spares consumption law confirmation method based on virtual prototyping, which purpose is to accurately forecast navy gun mechanical spares yearly consumption. Taking the drive system of naval gun for typical mechanical mechanism as an example, navy gun direction drive system key-valuable spares can be confirmed by FTA and FMECA. Direction drive system simulation model can be built by Virtual.Lab Motion simulation software, and which gear failure can be simulated and verified. Secondly, fatigue reliability life forecasting program and model is built, by which could get third level gears life in different reliability level. Finally, mechanical spares yearly consumption analytic model is built by mended check list method, and by which get direction drive system yearly consumption. Application result shows the method could accurately forecast mechanical spares yearly consumption.
