They are mortars , howitzers , cannons , long - range artillery , rocket guns and self - propelled guns 是迫击炮、榴弹炮、加浓炮、远程火炮、火箭炮、自行火炮。
In this paper , the decoupling of gun auto - aiming system and the disturbance restrict problem to stabilization system are studied 本文研究了自行火炮操瞄解耦和稳定系统的扰动抑制问题。
The development of the computer technology has provided powerful means for the automatic testing of the range - finding and aiming device 计算机技术的发展给自行火炮测瞄装置自动检测技术提供了强有力的手段。
In their fiscal year 1938 report krupp revealed that started on the design of a 105 mm k l 52 selbstfahrlafette . the machine was famous as dicker max 1938年，克虏伯公司开始着手研制一种105毫米自行火炮，该车被呢称为“迪克
In parallel with the conversion of captured tanks , research started in december 1942 for development of a romanian tank - destroyer 在用缴获苏联的坦克改装自行火炮的同时， 1942年12月开始考虑研制一种罗马尼亚人自己的坦克歼击车。
V ) the nonlinear dynamic response of vehicle , projectile , and gun barrel is derived by the nonlinear fem 5 、通过求解全炮非线性有限元模型，得到了某自行火炮发射全过程的车体大位移滑动、俯仰运动、炮口扰动等非线性动态响应。
Vi ) the interface between multi - body simulation system and i - deas is developed , and the visual simulation of self - propelled gun is fulfilled based on the i - deas platform 6 、编制了多体动力学数值仿真软件与i - deas的数据接口，实现了基于i - deas的自行火炮发射动力学仿真可视化。
Ii ) a 3 - d model and finite element model of a self - propelled gun is built . the intrinsic frequencies of all main assemblies and full gun are got , which are consistent with experiment data 2 、建立了某自行火炮的三维实体模型和全炮有限元模型，求解了各主要部件以及全炮的固有频率，与试验数据相比较符合较好。
Secondly , the stabilizer is designed by using h control theory aiming to the main disturbance of proper motion gun , which can reduce the disturbance effect on the gun - control system to the level of aspiration 其次，针对行进中自行火炮的主要干扰源，利用h _ 。控制理论，设计了稳定系统的镇定控制器，可将扰动对系统的影响降低到期望的水平。
In july 1929 the soviet government approved the first tank program , the goal of which was to bring into the inventory tankettes , light tanks , armored cars , self - propelled guns , tracked armored transporters , and other special vehicles 1929年7月苏联政府批准了第一个坦克计划，目标是生产超轻型坦克，轻型坦克，装甲汽车，自行火炮，装甲牵引车和其他专用车辆。
