摘　　要：文章通过对车用空调压缩机皮带轮高速运转过程中的径向及轴向跳动间隙进行模态分析,得出带轮在约束条件下的各阶模态。该结果对螺杆压缩机的优化可有效地控制振动、减小噪声辐射,并提高运行可靠性,为动力学分析和结构的优化设计提供可靠地理论依据。This paper through the modal analysis of the intervals of the radial direction and axial run-out during the process of the high-speed operation of the belt pulleys of vehicle air condition compressors, the study got the modalities in each stage under the constraint conditions of belt pulleys. The result can optimize helical-lobe compressors and can effectively control the vibration and reduce the noise radiation. In addition, it can improve the operational reliability and provide reliable theor- etical bases for dynamics analysis and the optimizing design of structures.
