Abstract:

In order to meet the development demand of the new type of strategic missile weapon, the servo mechanism is required to be compact in structure and highly integrated, and capable of adapting to the harsh working environment and the limited space structure, so as to measure and feedback the displacement of the servo actuator rack. Based on the traditional split type linear displacement sensor, the design of a four-redundant structure, the design of printed resistance film, the adjustable design of zero output The optimized design of multi-fingered brush enables the structure of the linear displacement sensor to be miniaturized and compact. It has high temperature resistance, long working life and high linear accuracy. Experimental and simulation analysis shows that the design of technical solutions is effective and can meet the requirements of the servo system.
