Abstract


With the development of power electronics technology and motor control technology has become increasingly widespread , servo system applications in the industrial , defense , aviation and aerospace . With the dynamic performance of the system is good or bad will affect the operation of the entire system , delivered in the servo system before the full bench test is very necessary . For this purpose , we developed the simulated load test rig of the servo system , servo system can be used for dynamic detection of static load simulation test and performance indicators . This paper first analyzes the development of the simulated load system and several commonly used form of simulated load , in summing up the basis of the traditional analog load system characteristics , combined with the actual load characteristics of the servo system , given the servo system is simulated load test rig the overall design of the program . The test bench by monitoring computer simulated load controller to simulate the load motor , motor drive , gearbox, inertia disc the hysteresis clutch test rig components , can be used to achieve inertial load of the servo system , static resistance moment, the dynamic moment of the analog variable . Followed by the the servo system simulated load test bench hardware selection and analog load controller hardware and software design and debugging . Simulated load controller is the core of the system control unit of the simulated load , high-performance DSP-TMS320LF2407A as the processor , to mainly complete signal acquisition , signal processing , and output in various forms of torque . The design work includes input modules , output modules , signal processing module , and to communicate with the monitoring computer software and hardware design of the module . Final assembly and commissioning of the complete servo system simulated load test bench , the debugging results showed that the test rig design is reasonable and feasible , the simulated load controller can successfully achieve the the dynamic torque analog signal input and output , and communication functions .
