National Key Discipline Lab of Armament Launch Theory & Technology, Second Artillery Engineering University, Xi’an 710025, China; 2. Brigade of Postgraduate, Second Artillery Engineering University, Xi’an 710025, China) Abstract: In order to obtain accurate pedestal oblique quantity, a method of demarcating measuring unit of the pedestal obliquity measuring system of gyroscope based on the least squares method was put forward. The essential principle of pedestal obliquity measuring system of gyroscope based on electrolyte obliquity sensor was introduced. The value and direction of the pedestal oblique were measured accurately. According to the data model between pedestal oblique and north-seeking precision effect, the north-seeking error was compensated. And the data were fitted according to the data model established by the least squares method. When the discrepancy between the measuring unit demarcated and theoretical design value was great, the unit could be demarcated again by adjusting the circuit magnification multiple. When the measuring unit demarcated was accord with the theoretical design value, the measuring unit demarcated was recorded and written into the flash unit of single-Chip microcomputer. Analysis result showed that measuring unit could be demarcated fast and easy by this measuring method, and the precision of north-seeking could be ensured.

A photoelectric check system used for measuring light scattering are designed, the system is made up of light path, photoelectric detector, data acquisition and control system, the software for correlation detection algorithm etc. On that basis, the phase lock algorithm based on LabVIEW software platform is studied mainly in this paper. The technique for phase locked detection realized by software in the weak photoelectric signal detection is raised, and the technique is simulated. When measured signal frequency is 0.2 kHz, amplitude is 1.0 V and the noise amplitude is 0.5 V, the measurement error is 0.1%. The simulation result shows that the detection for the modulated weak photoelectric signal can be realized effectively by this method. 合富金生买地板买晨找 Key words: weak scattering light signals; lock-in amplifier; modulating frequency; virtual instrument; correlation detection ********************************************************************************** 步兵买买塔振买炮仿真 刘全买～王买买～高玉水～李培富 (甲兵工程院兵器工程系～北京 装学100072) 摘要,买买某型履买式步兵买买火射买精度炮受塔振买影大的买买～在炮响ADAMS/ATV和SolidWorks买境下建立了 买化后的买买-路面系买买买机～建立了基于买波加法的机等买虚叠随虚学路面模型～分析了买买机中主要的力模型～引入 了买买买模型控制器～买步兵买买2,5档在B,E买路面上行买买程中塔的振买买行。买果表明～炮仿真仿真虚炮采用买买机买 塔振买分析的方法是有效的～买塔炮研瞄参乘买的舒适性究及准买买定分析提供考依据。 买买买,ADAMS/ATV～步兵买买～塔～振买～炮路面 Vibration Simulation of Infantry Combat Vehicle Turret Liu Quansheng, Wang Shuaishuai, Gao Yushui, Li Peifu (Department of Weaponry Engineering, Academy of Armoured Force Engineering, Beijing 100072, China) Abstract: Focused on the problem that gun firing accuracy was influenced largely by turret vibration of a certain type tracked infantry combat vehicle, a simplified virtual prototype of infantry combat vehicle-road system was established under the ADAMS/ATV and SolidWorks environment. The random grade road model was created based on the harmonic superposition method is established. Main mechanical models of virtual prototype were analyzed. Driver model controller was introduced, turret vibration of infantry combat vehicle when running on B to E grade road with 2 to 5 gear speed was simulated. The result indicates that it is effective to analyze turret vibration by using virtual prototype and can provide a reference for the research of turret crew comfort and the analysis of the stability of the line of sight.
