摘　　要：整车噪声传递函数是评价整车结构噪声传递特性的关键指标,噪声传递函数一般可以通过仿真计算或试验测试进行获取。本文以承载式车身和非承载式车身为研究对象,分别使用力锤法和体积声源法对其进行整车噪声传递函数测试。通过对测试结果进行分析,探讨两种试验方法的优劣,可为不同结构车型噪声传递函数的准确测试提供指导和参考。The vehicle noise transfer function is a key index to evaluate the vehicle structure noise transfer characteristics.The noise transfer function can be obtained by simulation calculation or test.In this paper,the load-bearing vehicle body and the non-load-bearing vehicle body are taken as the research object.The force hammer method and the volume sound source method are respectively used to test the noise transfer function of the vehicle.Through the analysis of the test results,the advantages and disadvantages of the two test methods are discussed,which can provide guidance and reference for the accurate test of the noise transfer function of vehicles with different structures.
