摘要:
为建立更为准确的火炮发射动力学仿真模型,以某型步兵战车高低机齿轮与齿弧为对象,对双齿啮合接触刚度系数进行了计算,并与整体ADAMS发射动力学模型进行了耦合。建立了齿轮与齿弧有限元模型,设置齿轮与齿弧初始啮合位置为双齿啮合区,采用罚函数法,求得接触力、接触间隙、接触渗透量等双齿区域接触特性,结合Contact接触力公式计算双齿接触刚度系数。以此为基础数据,建立了ADAMS步兵战车整车刚柔耦合发射动力学模型,对火炮行进间射击过程进行动力学仿真分析; 研究了2档车速下4种中等起伏路面条件下的行进间射击结构动态响应,齿轮、齿弧之间的动态间隙对火炮俯仰部分的空间指向的影响,分析结果表明,计算的高低机双齿啮合接触刚度系数能有效反映行进间射击过程中的动态特性,并为实现高机动条件下的高精度打击能力、提高射击精度提供数据基础。
Abstract:
To build the more perfect firing dynamics simulation model of gun,the elevating mechanism gear wheel and gear arc for infantry combat vehicle were taken as object,and the double tooth contact coefficient of elevating mechanism was calculated and combinded with the whole ADAMS firing dynamics model. The contact coefficient was joint in the ADAMS firing dynamics model. The gear wheel and gear arc were defined as flexible bodies,and the finite element model of the gear wheel and gear arc was built by applying ANSYS software,and the original tooth position was set to double-tooth meshing zone. Pure penalty method was adopted,and then the contact characteristics such as contact force,contact clearance and contact sink were calculated. Combined with contact force formula,the double tooth contact coefficient was calculated. The infantry combat-vehicle rigid-flexible firing dynamic model was built based on the contact coefficient base data,and the auto-gun firing process on the move was analyzed. The construction dynamics response of four middling road conditions in the second speed was studied,and the influence of dynamic clearance on gun was researched. The calculated contact-stiffness-coefficient can effectively reflect the dynamic characteristics in the launching process on the move,and the result can offer basic data for achieving the high-precision hit ability and increasing the firing precision.
