摘要
消毒柜是目前家用厨房电器中一个重要的组成部分,而消毒柜中下层碗篮的升降机构则是消毒柜设计中最主要的部分之一。基于项目中设计的消毒柜下层升降机构,利用ANSYS对机构的四连杆机构及传动轴、水平释放零件和水平释放触发杆主要受力原件进行有限元仿真分析。通过仿真结果可知:在施加额定的载荷或是外力后,四连杆机构以及传动轴、水平释放零件和水平释放触发杆的最大位移以及最大应力出现位置均符合实际情况分析;最大位移的值均位于安全范围之内;最大应力均远小于所用材料304钢屈服强度。满足设计要求及安全需求。
Disinfection cabinet is an important part in electrical appliances of home use kitchen at present,and the lifting mechanism of basket of lower layer in disinfection cabinet is one of the mainest parts in disinfection ark design.Based on the lower lifting mechanism of disinfection cabinet designed by the project,the finite element simulation analysis of four-link linkage and transmission shaft,horizontal release parts and main stress components of horizontal release trigger rod was carried out by using ANSYS.The simulation results show that:after the rated load or external force is applied,the maximum displacement and the maximum stress position of the four-link mechanism,the transmission shaft,the horizontal release parts and the horizontal release trigger rod are all in line with the actual analysis.The maximum displacement values are all within the safe range.The maximum stress is much less than the yield strength of 304 steel.Meet design requirements and safety requirements.
