“远舰”轿车双摆臂悬架的设计及产品建模 摘要：汽车双摆臂悬架是一种常见的悬架形式，合理的选择悬架的结构和几何尺寸是获得满意的汽车行驶性能的重要条件，其运动特性的优劣关系到汽车操纵稳定性，舒适性，转向轻便性和轮胎的使用寿命等分析了双摆臂独立悬架的组成和功用 需要全套设计的请加QQ174320523 各种专业都有 The Design and Product modeling of Double Wishbone Suspension of“Optima”Car Abstract：The double-wishbone independent suspension is one of the common forms of motor vehicle suspension. Choosing the geometry parameters of the independent suspension reasonably is one of the important conditions to obtain the satisfied character of service. Its state of motion is related to handling stability, comfort ability, handling of steering and the life of tire, ect. The subject comes from the rear suspension of “optima” car which made by DYK Co. Ltd. The double-wishbone suspension can be a reasonable choice of space-oriented bar articulated point. The location and orientation of the suspension arm length can produce suitable motions. This thesis first analyzes the consists and function of the double-wishbone suspension in the design, then checks the up and down of arms of the double-wishbone independent suspension, Thirdly, make a detailed consideration of the various components of the link between relations is made. I calculate the suspension on the basis of the natural vibration frequency, static suspension deflection and dynamic deflection and elastic characteristics of the suspension terms at last. On the basis of Analysis of the composition and role of the size of the components in the double-wishbone independent suspension, with CAD software and Pro / E, respectively, 2D drawings and 3D product Modeling are made. We made an accurate and detailed structural analysis on the design, which provides the?reference for optimal design of the double-wishbone suspension. The approach can improve the?performance of the double-wishbone independent suspension.
