梁分析作业剪力弯矩图悬臂矩形梁(均布载荷).doc

如图所示矩形截面悬臂梁，左端固定，梁的总长度l,矩形截面尺寸：H=80 mm，B=40 mm。CB段受均布载荷作用q，材料为钢。材料参数为：弹性模量E=200 GPa，泊松比u=0.28步骤：1、几何建模2、选择单元类型3、添加材料属性4、选择截面属性5、创建方向关键点6、网格划分 Element attributessetpick 1,22,3lines-okpick 100-ok选择使用关键点 Size controlssetpick1,22,3显示截面形状Plotctrl-style-size and shape7、 施加约束和载荷施加约束拾取点1施加载荷选择5,6,7,8段8、后处理显示变形查找beam189属性Help输入beam189进行搜索 查找SFZ的I和J值 I=5，J=18输入剪力常数 applyok查看剪力图查找MY的I和J值I=2, J=15输入弯矩常数查看弯矩图分析：由材料力学知识可知，剪力图左端为常数，即ql/2,右端为斜率为-q的斜直线；弯矩图左端为向上的斜直线，且左端点处弯矩为-3ql2/8,右端为开口向下的抛物线，并在右端点处有最大值，故所绘剪力弯矩图符合理论规律。office, branch offices (jurisdiction), risk management, marketing management sector through supervision and inspection found problems, should be assigned the investigators are corrected in a timely manner. 27th the fifth chapter penalty under any of the following acts, then the relevant provisions to punish the investigators, according to the Bank. To constitute a crime shall be investigated for criminal responsibility: (A) on the business that are not involved in the investigation, issued a survey.
