以便在他们的正常操作期间或在强烈地震下面评估到橡胶轴承(RB ) 的非线性的表演和可能的损坏,一个简化 Bouc 皮脂腺囊瘤模型被用来在这份报纸描述 RB 的非线性的 hysteretic 行为,它有的优点光滑变化、身体上激发。推进,基于从使用在不同刺激情形下面的 RB ( GZN110 )的一种特别类型执行的试验性的测试的结果,包括白噪音和几地震,一个新系统鉴定方法,叫作顺序的非线性的最少平方的评价( SNLSE ),被介绍识别模型参数。建议简化 Bouc 皮脂腺囊瘤模型能够描述 RB 的非线性的 hysteretic 行为,这被显示出,并且 SNLSE 途径在识别 RB 的模型参数是很有效的。关键词参数鉴定 - 忍受橡胶 - hysteretic 行为 -Bouc 皮脂腺囊瘤模型 - 顺序的非线性的 leasts-quare 评价旁边支持了:不到资助号码 10572058 的中国的国家自然科学基础;在资助 No.2008ZA52012 下面的中国的航空学的科学基础
In order to evaluate the nonlinear performance and the possible damage to rubber-bearings (RBs) during their normal operation or under strong earthquakes, a simplified Bouc-Wen model is used to describe the nonlinear hysteretic behavior of RBs in this paper, which has the advantages of being smooth-varying and physically motivated. Further, based on the results from experimental tests performed by using a particular type of RB (GZN 110) under different excitation scenarios, including white noise and several earthquakes, a new system identification method, referred to as the sequential nonlinear least- square estimation (SNLSE), is introduced to identify the model parameters. It is shown that the proposed simplified Bouc- Wen model is capable of describing the nonlinear hysteretic behavior of RBs, and that the SNLSE approach is very effective in identifying the model parameters of RBs.
