摘　　要：通过对路谱驱动汽车台架耐久性试验、汽车道路耐久性试验及载荷谱驱动汽车台架耐久性试验的试验车辆响应信号和台架信号的对比分析,探讨了路谱驱动台架耐久性试验的可行性。并依据对路谱驱动试验精度的分析,提出了提高试验精度的途径。Based on the comparison and analysis of test vehicle response signal and bench signal of the vehicle durability bench test, vehicle road durability test in road-profile drive and vehicle durability bench test in load-spectrum drive, the feasibility of road-profile driven durability bench test is discussed. And the method to improve test accuracy is proposed based on the analysis of road-profile drive test accuracy.
