Based on modeling and simulation of two kinds of atomizers with typical structure, this paper analyzes both atomization effects. then,based on the unrestricted atomizer structure,researches on and analyses its atomization effect under the conditions of setting up different parameters. The certain basis is provided for the actual production.The results show that the two kinds of atomi-zer structures have different characteristics.The atomization effect of the unrestricted atomizer is better than that of the restricted at-omizer, thus ensuring the ideal range of setting the parameters atomizer for the atomization effect of the unrestricted atomizer.%通过对两种典型结构的喷射成形雾化器进行建模、仿真,分析两种结构雾化器雾化效果的优缺点.以非限制性结构雾化器为基础,研究分析在不同参数设置条件下,雾化器的雾化效果,为实际生产提供一定的选择依据.结果表明:两种结构的雾化器各有特点,但非限制性结构雾化器的雾化效果比限制性结构雾化器的雾化效果更为理想,同时验证了确保非限制性结构雾化器雾化效果较为理想的各类参数设置范围.
