轮式装甲车辆动力舱振动测试系统研究

摘要

介绍了关于轮式装甲车辆动力舱动态参数测试系统的初步研究. 针对恶劣的测试环境, 设计了双层混合屏蔽的外壳, 也对电路本身进行了抗电磁干扰的设计, 对仪器高温防护设计进行了相关的分析, 并且采用分时/分区供电方式对系统进行了低功耗设计, 并采用了单片机与CPLD配合工作实现数据采集过程.%This paper mainly discuss the research on the dynamic parameters of the engine compartment of the wheeled ar-mored vehicle. It designs the bi-layer mixed shields to catering for the severe environment. Meanwhile, it also designs the anti-electromagnetic interference of circuit. Through analysis of the ability of high temperature resistance of the instrument. Adopt Time-sharing and district power supply to reduce the energy consumption, and the data acquisition is realized by the cooperation of SCM and CPLD.
