兆瓦级行星齿轮箱行星架结构有限元分析

Finite-element analysis of structure on the planetary carrier of the MW planetary gearbox

以海上钻井平台上兆瓦级传动齿轮箱中的行星架作为研究对象,为了减轻按经验公式设计的行星架重量,根据材料力学有关理论知识对行星架结构进行了修改,并采用有限元分析方法对行星架修改前后的应力、位移和安全系数进行了分析研究,取得了满意的结果,为高可靠度行星齿轮箱设计提供了有效的数值依据,它对相似机械产品的设计具有较大的参考价值。

It deals with the planetary carrier of the MW planetary gearbox which is used in the drilling platforms. In order to lighten the weight of the planetary carrier which is design according to the empirical formula,it change the planetary carrier structure according to the theoretical knowledge relating to the mechanics of material,and analyzing the stress,displacement and safety factor which is the parameter of the planetary carrier before and after the change used the finite-element analysis approach,we got the satisfactory results. It offer the effective numerical value basic for the high reliability design of the planetary gearboxes ,and offer the biggish reference value of the design of the similitude machine products.
