要緊步驟:

1、機構(gòu)自由度計算;

2、桿組分析；

3^Solidworks建模；

4^Admas建模；

5、仿真；

6、C點速度、加速度分析;

7、阻力矩分析;

8、查驗:①C點速度及加速度查驗;

②阻力矩查驗；

9、飛輪設(shè)計：①飛輪轉(zhuǎn)動慣量的計算；

②飛輪尺寸設(shè)計；

1.機構(gòu)自由度計算：F=5*3-2*7=l

2.桿組分析：拆桿組得

3.用Solidworks依照顆式破碎機的所給數(shù)據(jù)，對處于工作

行程極限位置1時的顆式破碎機進行簡單建模，確信各點的

精準坐標，用于輔助Adams的模型構(gòu)建，簡單模型如下：

單位：mm

06

02(0,0)；A(0.24,-100)；B(3.25,-1350)；0,(940,-1000)；

C(-1120.63,-1106.28)；06(-1000,850)；D(-1036.93,251.14)

其中：DF_L()6C,DE為一水平線,用于輔助Adams的載荷附加。

4.用Adams依照Solidvorks所得數(shù)據(jù)構(gòu)建顆式破碎機模型如下:

現(xiàn)在對應(yīng)于工作行程極限位置lo

給予各構(gòu)件相應(yīng)的質(zhì)量和轉(zhuǎn)動慣量:

給予顆式破碎機原動件驅(qū)動:

（順時針旋轉(zhuǎn)）角速度：1020°/s=170r/niin

隨后依照題R要求在桿6上添加載荷,

co

（step函數(shù)）

step(time,0,0,0.1823529412,85000)+step(time,0.1823529412,0,0.1823529413,-85000)

+step(time,0,0,0,3529411765,0)

5.進行仿真操作：

依照計算；運動周期T-2”/a-0.353s

因此取終止時刻為0.36,步長為0.01：

點擊綠色按鈕，進行仿真，原動件順時針運轉(zhuǎn)一周.

6.C點的速度、加速度分析:

按F8進入,'\dams/PoslProcessor進行分析，得C點的位移圖像:

C點位移（m）

找到桿6對應(yīng)的角速度和角加速度。桿6作定軸轉(zhuǎn)動,
