液压减震器设计说明书+外文.doc

摘 要 液压式减振器是车辆悬架系统中主要的阻尼元件，其性能好坏直接关系到整车的安全性及舒适性。其中活塞杆是减振器中重要元件，在工作中主要承受上下往复的运动。由于汽车要在不同工况下工作，活塞杆就要承受不同高度的运动，为了检测活塞杆在工作能承受工作载荷的极限设计了液压式减振器活塞杆拉断试验台。试验台采用四根立柱做为支撑，并对四根立柱做了强度和刚度的校核满足设计要求。四根立柱支撑上横梁采用光杠固定式，由上横梁上的液压缸施行拉断实验。并对试验台中的缸，泵，阀进行了计算选取了标准的元件。由于它，因而具有使用灵活，性能较高的特点。Abstract Hydraulic shock absorber, vehicle suspension damping system in the main components, the performance cars have a direct bearing on the safety and comfort. In the shock absorber piston rod which is an important component in the work of the major bear reciprocating movement from top to bottom. As car in different conditions, different piston rod to withstand high degree of movement, in order to detect rod in the workplace can withstand the work load limit was designed hydraulic shock absorber piston rod pull off test-bed. Test-bed for a four column support, and four pillars done a strength and stiffness of the check to meet the design requirements. 4 column on the support beams by light bars fixed by the beams on the implementation of hydraulic cylinders pull off experiments. Taichung and test the tanks, pumps, valves were calculated select a standard component. Because it used hydraulic oil as a power source, so they have flexibility in the use of noise and small, high performance characteristics. In addition the design of a more advanced design tools, calculated using C-language programming and graphics software with CAXA. Keywords : pull off; hydraulic; test-bed; shock absorber 目 录 第1章 绪论............................................. ...........1 1.1 液压式减振器活塞杆拉断试验台设计......................... ....1 1.1.1 概述............................................. .. .1 1.1.2 题目任务的内容和要求................................... 1 1.2试验台的功能设................................................2 第2章 试验台的性能计算...............................................3 2.1 试验台的尺寸控制图计算...............................3 2.2 外购件选择计算...............................3 第3章 试验台的结构设计...............................................7 3.1 活塞杆与夹具连接的螺栓强度校核
