设计简介
摘要
减震器主要用来抑制弹簧吸震后反弹时的震荡及来自路面的冲击。在经过不平路面时,虽然吸震弹簧可以过滤路面的震动,但弹簧自身还会有往复运动,而减震器就是用来抑制这种弹簧跳跃的。支架起支撑作用的构架。减震支架保护内装的零部件不因外部的冲击震动导致其损坏。
机械制造过程中用来固定加工对象,使之占有正确的位置,以接受施工或检测的装置,又称卡具。从广义上说,在工艺过程中的任何工序,用来迅速、方便、安全地安装工件的装置,都可称为夹具。在机床上加工工件时,为使工件的表面能达到图纸规定的尺寸、几何形状以及与其他表面的相互位置精度等技术要求 ,加工前必须将工件装好(定位)、夹牢(夹紧)。夹具通常由定位元件、夹紧装置 、对刀引导元件、分度装置、连接元件以及夹具体(夹具底座)等组成。
利用模型复现实际系统中发生的本质过程,并通过对系统模型的实验来研究存在的或设计中的系统,又称模拟。当所研究的系统造价昂贵、实验的危险性大或需要很长的时间才能了解系统参数变化所引起的后果时,仿真是一种特别有效的研究手段。仿真的重要工具是计算机。仿真与数值计算、求解方法的区别在于它首先是一种实验技术。仿真的过程包括建立仿真模型和进行仿真实验两个主要步骤。

ABSTRACT
Mainly used to suppress the vibration damper after a rebound during the spring and shock-absorbing impact from the road . After a rough road when , although shock-absorbing spring can filter the road shock , but there will be a reciprocating movement of the spring itself , and the damper spring is used to suppress such jumping . Bracket play a supportive role in the architecture . Built-in shock absorber bracket parts protection due to external shock and vibration without causing damage .减震器主要用来抑制弹簧吸震后反弹时的震荡及来自路面的冲击。在经过不平路面时,虽然吸震弹簧可以过滤路面的震动,但弹簧自身还会有往复运动,而减震器就是用来抑制这种弹簧跳跃的。支架起支撑作用的构架。减震支架保护内装的零部件不因外部的冲击震动导致其损坏。

ABSTRACT
Mechanical manufacturing process for fixing the object , so that occupies the correct position to receive the detecting means or the construction , also known fixtures . Broadly speaking , any step in the process , used quickly , easily and safely install the device workpiece can be called a fixture. When the workpiece on the machine , in order to make the surface of the workpiece can reach the size of the drawing requirements , and the mutual position of the geometry precision technical requirements and other surfaces , the workpiece must be installed prior to processing ( positioning ) , clip prison ( clamping ) . Fixture usually consists of a positioning element , clamping device, the knife guide elements , indexing device , connecting elements and specific folder ( clamp base ) and other components.
The nature of the model using the reproduction process occurs in the actual system and the model of the system through the experimental design to investigate the presence or system , also known as simulation. When the system under study is expensive , large or dangerous experiment takes a long time to understand the consequences caused by changes in system parameters , simulation is a particularly effective means of research . Computer simulation is an important tool . Simulation and numerical calculation, the difference between solving approach is that it is an experimental technique first . The simulation process including the establishment of a simulation model and simulation experiments of two main steps.
