㈢ 什么叫主振型
主振型从概念上讲其实就是振型,一个意思。
主振型:这种结构位移形状保持不变的振动形式可称为主振型或振型。
它具有两个特点:
①. 在振动过程中,两个质点具有相同的频率和相同的相位角;
②. 在振动过程中,两个质点的位移在数值上随时间而变化,但二者的比值始终保持不变。
㈣ 主振型是什么
采用刚性楼板假定时,T周期最长的振型为主振型。非刚性楼板时,参与质量最大的振型是主振型。
振型:在振动的任一时刻,各质体位移的比值保持不变,即振动形状保持不变,将此振动形式称为振型。
振型有如下特点:
1. 结构自振频率数=结构自由度数量;
2. 每一个结构自振频率对应一个结构振型;
3. 第一自振频率叫基频,对应第一振型;
4. 结构每一振型表示结构各质点的一种运动特性:各质点之间的位移和速度保持固定比值;
5. 要使结构按某一振型振动,条件是:各质点之间的初位移和初速度的比值应具有该振型的比值关系;
6. 根据多质点体系自由振动运动微分方程的通解,在一般初始条件下,结构的振动是由各主振型的简谐振动叠加而成的复合振动;
7. 因为振型越高,阻尼作用造成的衰减越快,所以高振型只在振动初始才比较明显,以后则逐渐衰减,因此,工程的抗震设计中仅考虑较低的几个振型。
㈤ 英语 语法成分 主语 谓语 宾语等或者结构的英文简写。例如 S V ADJ ADV 之类的
如下:
1、主语 subject S
2、谓语 predicate V
3、表语 predicative P
4、宾语 object O
5、状语 adverbial a
6、定语 attribute attrib
简介:
主语是谓语的陈述对象,如“我写字”中的“我”就是主语,它做出“写”这个动作,“写”则是谓语,用来陈述主语的动作,而“字”是接受谓语“写”这个动作的对象,它因此被称为宾语,有的语法书也称它为“客体”或“受体”。
主语是句子中的陈述对象,与英语语法也有相似之处。常常由名词、 代词、或 名词性短语充当。形容词、动词、 谓语性短语和 主谓短语也可充当主语。 句子成分划分时,主语符号为双横线。
㈥ 主振型的名词解释
对于简单的判断而言,采用刚性楼板假定时,T1为主振型,就是周期最长的那个振型。非刚性楼板时,参与质量最大的振型是主振型。
