- 针对某遥控武器站解脱装置内部的轴杆与铜套间磨损情况，基于Archard理论模型展开一系列磨损分析。首先结合解脱装置的使用情况分析轴杆和铜套间的磨损形式，然后利用Ansys中APDL命令激活Archard参数模型，并进行参数赋值，根据解脱装置实际运动情况求解不同工况下的磨损曲线。最后，利用结构-热耦合单元对磨损曲线进行温度修正并完成有、无润滑的摩擦应力分析。将计算结果与实际结合分析发现，工作环境下，周向运动的磨损量大于轴向运动的磨损量，这与该解脱装置的轴杆和铜套间的主要运动形式有关，观察轴杆处可看见粘着的铜呈现明显的环带状，磨损分析结果与实际磨损情况相符。本文分析结果对相似的磨损研究具有参考价值。
According to the wear between the shaft rod and the copper sleeve in a certain release mechanism of a remote control weapon station, a series of wear analysis is carried out based on the Archard theoretical model. Firstly, the wear form between the shaft rod and the copper sleeve is analyzed in combination with the service condition of the release mechanism. Then, the Archard parameter model is activated by using the APDL command in Ansys, and the parameter assignment is carried out. The wear curves under different working conditions are solved according to the actual movement of the release mechanism. Finally, the structure-thermal coupling element is used to modify the wear curve in terms of temperature. The friction stress analysis with and without lubrication is completed. After combining the calculation results with the actual situation, it is found that under the working environment, the wear amount of the circumferential movement is greater than that of the axial movement, which is related to the main movement form between the shaft rod and the copper sleeve of the release mechanism. It can be seen that adhesive copper at the shaft rod shows an obvious ring shape, and the wear analysis results are consistent with the actual wear situation. The wear analysis has a good reference value for similar wear research.
