primary design stage meaning in English

初步设计阶段

Meanwhile , on the fundamental parameters that can be acquired in the primary design stage of a new car or a car which it has put in used , this paper utilizes adams / car to establishes the simulation parametric modeling of a suspension according the topology structure of macpherson front suspension system , in this model , we considered the front suspension system , steering system and the tire model in detail , and the bushing effect was included in this study , and it is very convenience to carry out kinetics / elastic kinetics simulation . all kind of the suspension parameters on handling and stability and automobile comfort were analyzed
Adams的实体数值悬架运动学仿真分析为悬架的设计开发提供了一种先进高效快捷的方法。与此同时，本文依据麦弗逊式前悬架的拓扑关系，利用设计阶段的新车或者是正在使用的汽车的所能取得的基本参数，借助adams car建立了悬架参数化模型，在这个模型里，考虑了转向系统、轮胎、衬套等因数，因此可以方便地进行悬架运动学弹性运动学分析。
