【摘要】 文章介绍了一种新型的内燃机主要运动部件摩擦磨损与振动模拟试验机,基于虚拟仪器技术构建了一套试验机振动测试分析系统。采用LabVIEW的图形化编程语言,结合各种灵活设计的子Ⅵ对内燃机的振动测试系统进行设计,可以实现对模拟内燃机的缸套、活塞环、曲轴、轴承等核心部件的振动情况进行实时监测。系统将对六个不同测点的振动情况进行监测,通过对实时信号时域分析、频域分析、相位分析、功率谱分析、相关分析,完成对试验机振动状态的实时监测,验证了测试系统的可行性。更多还原

【Abstract】 The paper introduces a new type of abrasion and vibration simulation testing machine on the primary locomotion components of the gas engine,and design vibration test system of simulation gas engine on Virtual Instrument technology.It adopts LabVIEW’s graph programming language,unites all kinds of sub-Ⅵto design the vibration test system for gas engine,which can complete the real time inspection on the vibrating state of the core components of simulation gas engine,such as cylinder, piston ring,crankshaft,bearing etc.The system inspects the vibration from six different points,which complete the real time inspection on the vibrating state of gas engine through the analysis of the signal time domain,frequency scope,phase,power spectrum,correlation in real time,and validates the feasibility of the system.更多还原
