摘　　要：利用SolidWorks软件建立跌落模型,用Cosmosworks对模型跌落的过程进行仿真,并对结果做进一步的分析。结果表明,物体跌落很容易引起材料塑性变形,导致模型损坏;地板的材料硬度越大,模型损坏越严重;模型掉落姿态不变,重力与地面所成角度越大,产生的应力峰值越小;模型的掉落姿势不同时,与地面接触的面积越小,产生的应力就越大。Drop model is established by SolidWorks software, the processes and further analysed the results. The results showed that falling objects produce plastic deformation, lead to damage of model; and the harder the of the falling is simulated, can easily make material materials of floor was ,the more severe the model was damaged; while the model maintained the same falling posture, the greater angel that was formed by gravity and ground was, the smaller stress was; while the falling posture of the model is diffrent, the smaller contacting area with the ground was, the greater stress was.
