【摘要】 采用单轴激振的台架试验方法，得出在整车安装条件下的车架一阶扭转和一阶弯曲模态，考察各振动传递环节的传递特性，为平顺性改进提供了理论根据。给出了平顺性改进后的试验结果。更多还原

【Abstract】 A single axle exciting vibration bench testing method has been adopted in the rid-ing stability improvement of a light truck. Primary torsional modal and primary bending modal oftruck frame are obtained in the test under the installation condition of the complete truck. Theore-tical basis are provided for the riding stability improvement by surveying the transmitting charac-teristics of various transmitting links of vibration. Also test result is given out after the improve-ment.更多还原
