摘　　要：针对某氢燃料电池客车转向系统噪声问题,以车内后排位置为目标点建立转向系统噪声OTPA模型,并进行仿真分析。结果表明,转向泵本体辐射的空气声是后排座椅噪声最主要的贡献源。Aiming at the noise problem of the steering system of a hydrogen fuel cell bus,the authors establish the noise OTPA model of the steering system with the rear seat position in the bus as the target point and carry out the simulation analysis.The results show that the air noise radiating from the steering pump body is the main contribution source on the rear seat noise.

关 键 词：氢燃料电池客车 OTPA 转向系统 噪声传递
