tight bushing meaning in Chinese

紧固衬套

The quality of machine with loading and unloading bushing has been improved and the structure of which has been turned rationalization ; fourthly , according to the relation of the tight fitting between resist grind bushing and suspension yoke , making use of the two simple thick circles theory in the elastic - plastic mechanics and the fourth strength theory , it integrated theory with it ' s formulation characteristic and developed the solver of the tight fitting force in the system of c + + builder . it could realize the solve of all tight fit force and save up the frame ' s size and the tight fitting ' s data in database in order to use in the future ? the assemble force of tight fitting can be used as the rule of estimating loose or tight bushing in theory
3 ) 、利用了ansys8 . 0自带的opt (优化技术)对c型夹具进行了结构上的优化，实现了一定强度和刚度的条件下， c型夹具的质量最小，使装、退套机的质量得到了改善，结构更趋于合理化； 4 ) 、根据合金套和吊耳的过盈配合关系，应用弹塑性力学中的两个简单厚臂圆筒理论及第四强度理论，结合轴套装配方案特性，在c + + builder平台上开发出了过盈配合装配力的求解器，它能求解出所有过盈配合所需装配力，并将各种配合尺寸和过盈量的数据库存化，以便将来调用。
