双电机冗余驱动加油开关齿轮减速机构设计

Design of the Gear Reducer Mechanism with Double Motor Redundancy Drive of the Refueling Switch

对加油开关齿轮减速机构进行设计与分析,综合考虑设计工况及设计要求,对其进行建模以及静力学分析和加速冲击动载荷仿真分析。结果表明,设计的加油开关齿轮减速机构满足设计要求和设计工况,其最大应变、最大变形和最大瞬时冲击应力均小于许用值。加工的实物验证了有限元模型的准确性,经过试验能够实现各项功能且并无干涉,完全符合设计要求。

The design and analysis of the refueling switch gear reducer mechanism are carried out. Withinthe design conditions and design requirements comprehensively considered, the modeling,statics analysis andacceleration impact dynamic load simulation analysis are carried out.The results show that the designed gear re-ducer meets the design requirements and design conditions,and the maximum strain,maximum deformation andmaximum instantaneous impact stress are less than the allowable value.Besides, the accuracy of the finite ele-ment model is verified by the real object, and all functions could be realized through the test without interfer-ence,which fully meet the design requirements.
