运用CATIA软件建立了专用车制动盘的三维模型,导入ANSYS软件对其进行了模态分析,得到制动盘的固有频率及振型特征,与激振频率进行对比,尽量避免产生共振和噪声,为实际模态试验提供参考和依据。
The CATIA software was used to establish the three-dimensional model of the special-purpose vehicle brake disc. The software was imported into ANSYS to analyze the modal characteristics of the brake disc. The natural frequencies and mode shapes of the brake disc were obtained and compared with the excitation frequency to avoid resonance and noise , For the actual modal test to provide a reference and basis.
