随着大功率涡旋压缩机的快速发展，涡旋压缩机的动态性能对整机的振动和噪声有着重要的影响。因此，本文通过仿真和实验研究了高速钢结构在动态激励下的动态特性和结构声辐射特性。首先，建立了高速列车的动力学仿真模型，分析了轴承激励和上支承激励的时域和频域特性。同时，建立了机架、上支承和下支承的有限元模型，分析了机架在激励源作用下的瞬态动力响应。基于壳体表面的振动位移，建立了壳体辐射噪声的预测模型，并对壳体表面辐射噪声和标准化测试点的噪声频谱进行了分析。最后通过声学实验验证了预测模型的准确性。实验结果表明，通过合理建模计算气体力，近似实际气体载荷，可以准确预测壳体的振动和辐射噪声。壳体耦合系统的振动是影响高速列车振动特性的主要原因。研究结论可为高速开关电源的低噪声设计提供参考。
With the rapid development of a high-power scroll compressor (HSC), the dynamic performance of a scroll compressor has an important impact on the vibration and noise of the whole compressor. So, the dynamic characteristics and structural acoustic radiation characteristics of HSC under dynamic excitation are studied by simulation and experiment in this paper. Firstly, the dynamic simulation model of HSC is established to analyze the time-domain and frequency-domain characteristics of bearing excitation and upper support excitation. At the same time, the finite element models of housing, upper support, and lower support are constructed to analyze the transient dynamic response of housing under the excitation source. Based on the vibration displacement of the housing surface, the prediction model of the housing radiated noise is also established, and then the radiated noise of the housing surface and the noise spectrum of the standardized test points are analyzed. Finally, the accuracy of the prediction model is verified by acoustic experiments. The experimental results show that the vibration and radiation noise of the housing can be accurately predicted by reasonable modeling to calculate the gas force and approximate the actual gas load. The vibration of the housing coupling system is the main source of the vibration characteristics of the HSC. The conclusions of the study can provide a reference for the low noise design of the HSC.
