摘要
Abstract
It will produce high axial overload environment when the grenade launches in a horizontal state,and the propellant grain length contraction deformation will lead to the generation of overload displacement in this environ-ment. The Position Sensitive Device based on the lateral photoelectric devices of the photoelectric position is sensitive,and it has a high position resolution,fast response,simple processing circuit,etc. In this article,discussing the principle of one-dimensional PSD displacement measurement and its related features,the FPGA master control module is taken as the core to set signal conditioning,acquisition and storage functions in one,and innovates on design of the integrated measuring system of sensor and to housing. The paper discusses the test system modules,processes and analysis of innovation on the measurement data at the same time, the polynomial fitting curve is adopted to improve the measurement accuracy of the system. From the high overload test experiment the system is reliability and stability. It provides a reliable experimental data for the establishment of the evaluation method of the displacement of the grain.关键词
