摘要
路面激励作为汽车在行驶过程中的重要激励,其质量的好坏直接影响到汽车悬架分析以及振动分析的准确性。鉴于此,利用Simulink平台,建立了A,B,C级路面的不平度仿真分析模型。并利用滤波白噪声的方法,分别模拟了A,B,C级路面的不平度功率谱。并与目标谱的随机高程均方根值相比较,得到的结果与目标谱非常一致。验证了所建立模型及运用方法的正确性。
Road roughness is an important indicator of road quality.As the main incentive of the car during driving process,the quality of the road directly affects the accuracy of the car suspension analysis and vibration analysis.We use the Simulink platform to establish a simulation analysis model for unevenness of A,B,and C road surfaces.And using the method of filtering white noise,the uneven power spectrum of A,B,C grade road surface is simulated.Compared with the random elevation RMS value of the target spectrum,the results are in good agreement with the target.It verifies the correctness of the established model and application method.
