An example of automobile components assembly using catia

products using CATIA V5 version. This research was reviewed all step from the beginning to the end of the process design which help the new researchers easy to follow step by step. 1. INTRODUCTION -In this part, we will connect all component together and it will base on assembly to simulate Fig.1. Main component The excavators are one of the earth movers playing a major role in the development of the infrastructure like excavation, road construction, building construction, granite mining, ore mining, Coal mining etc. Excavators are generally equipped with a work implement or attachment for performing useful work. And this report will figure out the Excavator simulation. How does it work and each component of it. 2. MODELING DESIGN In Excavator, we have 2 kind of element: Active Element and Passive element Active element: Front arm, back arm, bucket, body, hydraulic cylinder. Passive element: Base, cabinet, arm support, exhaust. 1387 Fig.2. Front Arm Fig.3. Back Arm Fig.4. Bucket Fig.5. Body – We have 3 kind of Hydraulic cylinder: + Boom Cylinder + Arm cylinder + Bucket cylinder – Each cylinder have a different dimension because depend on angular and, its responsibility and your design Fig.6: Arm cylinder Fig.7: Boom Cylinder Fig.8: Bucket Cylinder After Active element,we move to Passive element: Fig.9: Cabinet Fig.10: Arm Support Fig.11: Base 1388 Fig.12: Exhaust 3. SIMULATION This is an important part,it is decide the excavator simulation. So in this case,do it correctly. Step 1: Create a new product:  Start  Digital Mockup  DMU Kinematics  In new Product,Click right mouse to ―Product‖ and choose ―Properties‖ +The table of ―Properties‖ will be shown 1389 +In ―Part Number‖,clear ―Product1‖,and change to Excavator Simulation + Then click ―Ok‖ to change Product name Step 2: Existing component After change Product name,we start to exsit component + We Click to the name ―Excavator simulation‖ for red color (Not blue color) 1390 + In taskbar,we choose ―Insert‖ Existing component + Table ―File selection‖ will be shown and we choose all file which is excavator component + All the component will be shown Step 3: Hide the component that is not necessary: Step 4: Click ―Revolute Joint‖ to join Base and Body Step 5: Join Body and Cabinet Step 6: Body and Arm support Step 7: Exhaust and Body 1391 Step 8: Join Back arm and Arm support Step 9: From arm and Back arm Step 10: From arm and Bucket + Choose ―Bucket ― File on the tree and show it + Choose ―Revolute joint‖ and choose two line as a picture 1392 + And plane as a star position + But if you want to simulate,you have to choose an ―Angle Driven‖ + If table ― The mechanism can be simulate‖ that you can simulate the excavator 4. CONCLUSION This paper was shown the process of vehicle body design using CATIA which help the automobile makers quickly to produce new car for future. REFERENCES 1393 [1] [1] N.P.T.
