For the vibration and noise issues generated by the Rack-parallel Electric Power Steering (R-EPS) system under bumpy road conditions, this study analyzes the overall vibration transfer characteristics of the structure from the perspective of vibration transfer functions, identifying the primary frequency band of the abnormal noise. Meanwhile, modal analysis is employed to determine the correlation between the system's characteristic frequencies and its natural frequencies and mode shapes, confirming that the transfer function from the inner ball joint of the tie rod to the ball screw structure exhibits significant characteristic frequencies within the noise frequency band. To improve noise performance, based on the concept of transfer path optimization, rubber bushings were added to the mounting holes between the steering gear and the subframe to alter the stiffness and damping of the structural vibration transfer path. The effectiveness of this measure in optimizing the vibration transfer path was validated through CAE analysis and testing.

针对平行轴式电动助力转向器(R-EPS)在颠簸路面条件下产生的振动噪声问题,从振动传递函数角度出发,分析结构的整体振动传递特性,确认了异响的主要振动频带,同时结合模态分析确定了系统特征频率与固有频率、振型之间的关联性,确认了由拉杆内球头到滚珠丝杠结构处的传递函数在噪声频带内存在显著特征频率。为改善噪声表现,以传递路径优化思路为基础,在转向器与副车架的安装孔位置增加了橡胶衬套,改变结构振动传递路径的刚性与阻尼,并通过CAE分析与试验验证了该措施对振动传递路径优化的有效性。

针对平行轴式电动助力转向器(R-EPS)在颠簸路面条件下产生的振动噪声问题,从振动传递函数角度出发,分析结构的整体振动传递特性,确认了异响的主要振动频带,同时结合模态分析确定了系统特征频率与固有频率、振型之间的关联性,确认了由拉杆内球头到滚珠丝杠结构处的传递函数在噪声频带内存在显著特征频率。为改善噪声表现,以传递路径优化思路为基础,在转向器与副车架的安装孔位置增加了橡胶衬套,改变结构振动传递路径的刚性与阻尼,并通过CAE分析与试验验证了该措施对振动传递路径优化的有效性。

For the vibration and noise issues generated by the Rack-parallel Electric Power Steering (R-EPS) system under bumpy road conditions, this study analyzes the overall vibration transfer characteristics of the structure from the perspective of vibration transfer functions, identifying the primary frequency band of the abnormal noise. Meanwhile, modal analysis is employed to determine the correlation between the system's characteristic frequencies and its natural frequencies and mode shapes, confirming that the transfer function from the inner ball joint of the tie rod to the ball screw structure exhibits significant characteristic frequencies within the noise frequency band. To improve noise performance, based on the concept of transfer path optimization, rubber bushings were added to the mounting holes between the steering gear and the subframe to alter the stiffness and damping of the structural vibration transfer path. The effectiveness of this measure in optimizing the vibration transfer path was validated through CAE analysis and testing.
