I graduated in July 15, so far more than four years has been engaged in the design and development of automotive wiring harnesses, specifically as a product engineer position, the harness more or less have some basic understanding of the product engineers daily use of the most is the CAD and wiring harness 2-dimensional design software VESYS, CATIA is an automotive wiring harness 3D engineers often use the software, I am out of interest in CATIA, as well as found online about the wiring harness 3D design software catia use. Interest, as well as found on the Internet on the harness 3D design information is very little, it is here to organize some self-study experience, I will be divided into three parts to share with you how to use CATIA to draw the automotive wiring harness:
First of all, I believe that many beginners do not know much about automotive wiring harnesses, if you don't know the structure of the wiring harness, even if you will be using CATIA is also very difficult to draw.
The definition of automotive wiring harness in Baidu Encyclopedia is: automotive wiring harness is the main body of the network of automotive circuits, there is no wiring harness there is no automotive circuit. Wiring harness refers to the contact parts made of copper punching terminal (connector) and wire and cable crimping, and then outside the plastic pressure insulator or external metal shell, etc., to wire harness bundled to form a connected circuit components. Wire harness industry chain including wire and cable, connectors, processing equipment, wire harness manufacturing and downstream application industry, wire harness applications are very wide, available in automobiles, household appliances, computers and communication equipment, a variety of electronic instrumentation, etc., the body harness connects the entire body, the general shape of the H-shaped. I would like to add that automotive wiring harnesses are similar to human nerves, which play a role in conducting signals and electrical energy. Its importance to the car cannot be overstated. If a circuit is broken somewhere, there may even be a failure of the vehicle to start. This analogy is not a bit of a concept!
Next, we need to install CATIA on their computers, specifically V5R20 or V5R21, the installation package and installation tutorials can be their own Baidu, I would like to remind that the R21 is a high version of the R20, higher compatibility, we combined with their own situation to install, regardless of which version can be used for wiring harness design. After installing CATIA, you need to have a general understanding of the software, I have a semester class in my senior year before learning software modules specifically taught CATIA, did not learn it does not matter, to provide a self-study site (/list.aspx?cid=448). Due to the powerful CATIA, only the most basic commands have an understanding of the harness design, we take the time to learn the above tutorials in the content, and then come back to see this article, I believe you must be very helpful.
We are learning to understand the process of CATIA, I recommend that three modules focus on learning, they are:
This module needs to focus on learning, because a lot of complex parts are broken down into a simple composition of parts, wiring harnesses are not an exception. Automotive wiring harnesses include: wires, connectors, clips, rubber boots, terminals, waterproof plugs and so on. We draw the wiring harness, often need to connectors snap the number of models, such as TE's connectors can be found from most of the official website, if encountered without the number of models of the case, then we need to use this module of the parts design for the drawing of connectors snap, although we do not have to draw particularly accurate, but the general appearance of the dimensions to be accurate, because this involves interference issues, you will slowly understand later.
In this module, I most often use the product view commands under the existing parts command and product structure tool commands under the operation and capture commands. Where the Existing command serves to allow you to import other data under the existing Product and the Manipulate and Snap command allows you to move the imported data to place it where you want it.
I'm still learning this module, and I'll slowly share my experience with you later. According to the 3D gods around me to emphasize that this module is also vital, we have to learn it well oh
