摘　　要：研究了目标一致逼近模型的建立和模型修正的敏感参数分析。以一个弯曲钢棒结构的缩尺试样为对象,利用试验提供的测试结果,研究这类弯曲加工结构的模态参数目标模拟过程,使建立的模型能够逼近2个测试目标,即结构的模态频率和主振型,并对影响因素进行分析。The two key issues of this article are the same approximation of the model and analysis of the sensitive parameters in model amendment.The object of this research is the sample of a metal stick,using the experimental test results provided,studied the modal parameters simulation process of such bending target,so that the model can approach the two test targets that the structure of the modal frequencies and vibration mode.Then the influencing factors were analyzed.

关 键 词：加工硬化区 目标模拟 模态参数 模型修正
