摘要
针对某水下航行体半实物仿真的需要,结合水压仿真器技术指标要求,提出了一种新型的水压仿真器实现方案,测控系统采用上下位机结合的方式,上位机采用性能稳定、便于人机交互的工控机,下位机基于PC104总线的嵌入式微处理器硬件设计,该种处理器处理、计算速度极高且抗震性强、功耗低,结合下位机操作系统采用的硬实时操作系统VxWorks,从控制系统角度大幅度提高了水压仿真器的动态响应能力,而液压系统采用集成化设计以减少油压管道损失,电机及泵组采用旁置式安装方式,有效改善液压泵的吸入性能,以防止了液压泵油口处产生过大的真空度,避免吸空或气穴现象,选用高响应的两级力反馈式电液伺服阀作为液压系统的压力输出单元,以满足现阶段某产品半实物仿真的需要。
According to the hardware in-the-loop simulation requirement for one under-water vehicle, combined with the technical specification of water pressure simulator, implementation scheme of a new pressure simulator was put forward. The measurement and control sys tem using the methods of host computer combined with the lower computer, embedded microprocessor hardware design based on PC104 bus was used in the lower computer which Calculation speed is extremely high, strong vibration resistance, low power consumption, and operating system using hard RTOS for improving the ability-dynamic response from the point of view of control. Hydraulic system using integrated design in order to reduce pipe losses, using the force feedback, two stage of electro-hydraulic servo valve in dual-nozzle flapper as pressure output unit, ments the requirements of the hardware in-the-loop simulation requirement for one under-water vehicle at presents.
