摘　　要：为了提高播种机零部件的设计效率,将SolidWorks软件引入到了播种零部件数字化设计平台上,并利用VC对SolidWorks进行了二次开发,实现了播种机零部件的参数化设计。在设计零部件时,无需从底层进行建模,直接在VC界面输入相关参数,便可以自动生成零部件,有效提高了播种机零部件的设计效率。以播种机耧脚的参数化设计为例,对播种机多耧脚进行了设计,并对其应力应变等进行了分析。结果表明:采用参数化设计方法可以快速建立多个耧脚模型,并可以直接通过软件进行应力、应变等分析,在建模的同时实现了零部件的优化设计。In order to improve the design efficiency of seeder parts,SolidWorks software is introduced into the digital design platform of seeder parts,and SolidWorks is redeveloped by VC,which realizes the parametric design of seeder parts.When designing the parts,there is no need to model from the bottom,and it is directly in the VC interface.By inputting relevant parameters,parts can be automatically generated,which effectively improves the design efficiency of the parts of the seeder.Taking the parameterized design of the seeder's crowfoot as an example,it designs the multi-foot of the seeder and analyses its stress and strain.The design and analysis results show that the parameterized design method can quickly establish multiple foot models,and can directly analyze the stress and strain by software.At the same time,it realized the optimization design of components.
