Research on In-Situ Test Instrument of Self-Propelled Gun Servo System

To fulfill demands of quickly testing servo system of new self-propelled gun,a kind of testing instrument was developed based on in-situ testing technology.The instrument can not only automatically test the power signal,control signal,feedback signal and locked signal of the servo system,but also automatically input stimulating signals.The angle signals produced by servo systemsensor were sampled synchronously with the help of digital S/D converter.By means of data analysis and process,theservo system characteristics data,such as variable-speed,gun rotating accuracy,rotating time and so on,can be acquired.
