摘要
在抛丸过程中,高速撞向靶材表面的弹丸呈现高度随机性。采用MATLAB软件建立了大量弹丸随机分布的模型,利用ABAQUS软件中单个弹丸所形成弹坑的有限元仿真结果,获得覆盖率与弹丸个数的关系,并采用ABAQUS软件对50%、100%和200%覆盖率的情形进行有限元仿真。相比已发表的弹丸阵列分布模型,显然该模型更接近于实际抛丸过程。
During shot blasting,lots of randomly distributed shots hit the target surface at high speed. A model of randomly distributed shots was built by Abaqus software,finite element simulation result of a pit formed by a single shot was get,the relationship between coverage and number of shots was obtained,3 kinds of coverage（50%,100% and 200%） was simulated by Abaqus software. Compared with the published model with array distributed shots,it is obvious that this model is more close to the actual shot blasting process.
