变排量斜盘式压缩机的斜盘倾角会随着汽车环境热负荷的变化而在一定范围变化,此外汽车行驶中发动机转速也是变化的,这使得压缩机的动不平衡量不断的改变。我们利用ADAMS动力学仿真软件建立了上海易初通用机器有限公司6Sxx变排量斜盘式汽车空调压缩机的力学仿真模型,在理论分析的基础上,仿真了6Sxx变排量压缩机的动平衡特性,分析了在低、中、高不同主轴转速下和多种斜盘摆角下的动不平衡量,并得出了一些规律性的结论。 Variable displacement swashplate tilt angle with the car will change with the thermal load in a certain range of changes, in addition to the car engine speed is also changing, which makes the compressor unbalance constantly changing. Based on the theoretical analysis, we simulated the dynamic balance of the 6Sxx variable displacement compressor by using ADAMS dynamic simulation software. Characteristics, the dynamic unbalance under different rotational speeds of the low, medium and high spindle swings and various swashplate swings is analyzed, and some regularities are concluded.
