对农业机械上某些复杂、通常又是多次超静定的支承系统,设计部门历来都是采用传统方法,根据工程经验、直观分析以及参照原型样机,确定其构件横截面的几何尺寸。用结构力学的方法,按照强度条件校核支承系统各个构件,选择满足强度条件的横截面尺寸。 For some complex, often multiple, statically indeterminate support systems on agricultural machinery, the design department has traditionally used traditional methods to determine the geometric dimensions of its cross-sectional dimensions based on engineering experience, visual analysis, and reference prototype prototypes. Structural mechanics method, according to the strength of the conditions of the support system to check the various components, choose to meet the strength of the cross-sectional size.
