摘要: 在航空叶片振动疲劳试验自动化中,根据疲劳振动试验的参数要求,调控系统组成如图1所示。其中A/D装置的转换时间为20μs,D/A装置的转换时间为3μs。在D/A板上还装有由两个16Bit计时器构成的32Bit计时器,并由软件规划成按日、时、分、秒计时的时钟。Abstract: This paper describes how a microcomputer is applied to a blade fatigue testing system. Automatic checking and controling of blade fatigue testing in the system are implemented with the aid of a nest-form of assembly language and high-level language. The system can also be used for fatigue testing of fuel or oil tubes.
