Electrical and mechanical routing theory concepts using UG-NX
- 1. Electrical routing using NX Wiring & Harness by Ravindra Shinde
- 2. Routing elements • Components (like clamp, connectors etc.) • Path • Port First of all what is wire harness: It is a group of wires and cables that are bundled together and routed in various configurations. You mainly find it in medical industry(Instruments and equipment's) and automotive industry (component packaging and Integration)
- 3. • Path consists of segments and RCP • RCP stands for routing controlled points
- 4. Types of ports 1. Fixture port: Point where routing passes through (Always created on clamps and clips) 2. Multi port: Different connections inside the connector 3. Fitting port : Where actually routing starts, starting point
- 5. Basic Electrical routing procedure • Step 1: Qualify the standard components • Step 2 : Create the file for the electrical routing assembly • Step 3 : Properly place and position the electrical components • Step 4 : Create the necessary paths between the electrical components • Step 5 : Edit path if required • Step 6 : Apply stock (Just giving some thickness to segment)
- 6. • Qualifying part : Adding some specific intelligent to part. All connectors and fittings should be qualified • Usually we see paths are available outside the connector, but Build in paths available inside the connector • To some extend spline goes straight in direction of connector and then takes turn is called as extension length. This same we observed in actual wire harness too • If we have multi ports and all of them going to join at single point or this cut back length is given
- 7. Path types in routing • Linear path • Spline path • Defining path using points • Locked path- with alternation of points length of spline remain same • Slack mode: Needed when cable/wire get stretch in certain situation. • Stocks with some predefined shapes such circular, rectangular
- 9. Mechanical routing using NX Piping & Tubing by Ravindra Shinde Good piping should not involves lots of bends and turns, Also it should not be too long since frictional loss increases in such cases, At turns generally elbows are preferred which also fasciallate the easy maintenance
- 10. • Exactly similar to wire harnessing module • Heal Path: Use to find collision detection in routing; Also it finds it’s own path through any room. It looks for beat possible path with consideration of minimal length and hole presents near by • If OEM model the housing on themselves, then as discussed earlier firstly component requires Qualification wali step. But chances of these is less than 1% Path defining and editing commands Stock selection from template library and relevant editing Part selection from STL like connectors, Reducers With integration of SAP and Agile database, Hoses vendor and corresponding prices are provide by them. After Complete routing and harnessing; cost related to every variant can easily be evaluated.
