摘　　要：在进行室内汽车道路模拟试验时,对由振动台架和被试对象组成的试验系统,准确地辨识出系统特性是实验取得成功的关键步骤之一。详细论述了利用CARMA模型识别道路模拟试验系统的原理和过程。基于单输入单输出系统的时域CARMA模型,通过优化算法和系统辨识的方法识别了模型参数及模型阶次,并通过试验验证了这种方法的正确性。While a road simulation test is held,identification of the characteristics of the test system is one of the core steps for the success of the test ,which consists of vibration platform and the tested objects. The principles and process of the application of CARMA mo^lel to identify road simulation test system is discussed. Based on the CARMA model of SISO system in time domain,the model parameters and model orders by using the method of the union of system identification and optimum algorithm are given. And this method is proved to be correct by test data.
