某火箭炮方向机主齿轮啮合动力学特性分析

摘要

The main gear dynamics meshing of rocket launcher traversing mechanism directly affects the performance of azimuth transmission system. The mechanic electronic coupling model of azimuth transmission system was established based on ring gear traversing mechanism and control method. The main gear dynamic response on distinct drive stages was studied in four conditions: full load on the ground vertically, no-load on the ground vertically, full load on the ground slope and varying load torque. All the analyses will provide technical references for the design of azimuth transmission system and system life span and safety evaluation.%火箭炮方向机主齿轮副的啮合特性直接影响火箭炮方位传动系统性能.针对某火箭炮齿圈式方向机结构及其控制方式,创建方向机机电耦合系统仿真模型.通过结构模型和控制模型之间的数据交互,仿真分析火箭炮在满载水平地面、空载水平地面、满载倾斜地面和力矩干扰4种典型工况下方位调炮不同阶段主齿轮啮合特性.研究结果可为火箭炮方向机结构设计、伺服控制设计以及其寿命和安全性评估提供参考.
