| 中文摘要: |
| 为了解决压气机可调静子导叶（VSV）机械滞后问题，基于SimulationX 系统仿真平台，建立了VSV 调节系统仿真模型。通
过仿真结果与台架试验数据对比分析，验证了模型的有效性。在此基础上，结合FMEA 方法分析了不同因素对VSV 角度滞后的影响
程度。分析结果表明：发动机个体分散度和不同热状态之间的驱动负载、驱动能力、活门特性的差别是引发问题的主要因素，当由2
种以上因素共同作用时，VSV 角度的机械滞后效应增加。提出了1 种新的故障模式，并通过台架试验完成了验证。 |
| 英文摘要: |
| In order to solve the problem of mechanical hysteresis of compressor VSV,the simulation model of VSV regulating system
was established based on SimulationX system simulation platform. The validity of the model was verified by comparing the simulation results
with the bench test data. On this basis,the influence of different factors on the angle hysteresis of VSV was analyzed by FMEA method. The
results show that the main factors causing the problem are the difference of driving load,driving ability and valve characteristics between
individual dispersion and different thermal states of the engine. When two or more factors work together,the mechanical hysteresis effects of
VSV angle increases. A new fault mode is proposed and verified by bench test. |
