摘要
背盘是影响增压器质量的重要因素。利用有限元方法分析某型增压器背盘产生较大变形的原因及其背盘结构改进的方向。首先分析了背盘在正常条件下的变形,然后分析了在不正常手持时的背盘变形,最后分析了不正常装配是否会产生较大变形。通过上述几种分析结果获得了该背盘大变形的原因及解决办法。
The back plate of a turbocharger is an important contributor to turbocharger quality. This paper analyzes the main reason of back plate deformation and the direction of back plate structure improvement based on finite element analysis. Firstly, the deformations of a back plate are analyzed under normal deformation condition and under the condition of abnormal handhold. Then whether an irregular assembly will lead to a large deformation is analyzed. Based on above analyzed results, the reason for big deformation and the solution to the problem are obtained.
