摘　　要：物体作用于某一构件一般有3种情形:静加载、骤然加载和冲击,3种情形的模拟演示对明确概念,掌握知识非常有帮助。文章以冲击物作用于简支梁这一具体问题来细致描述静加载、冲击物从高度等于零的位置突然释放和冲击物从不等于零的某一高度释放这3种情形。从设计思想、理论依据到处理方法阐述模拟过程,给出用户界面。The simulative demonstrations of the ways that an object acts upon a simply supported beam are introduced. The acting ways are commonly divided into three situations:loading statically,loading suddenly( h=0, h is the distance between the object and the member) and impacting( h≠0 ). The interactive demonstrations of these three situations are helpful for students to make the concept clear and master the knowledge. The designing ideas,theoretical basis and simulation methods are described. The user interface is also provided.
