Mechanical Design Wing
1.0 Design wing setup:
Design wing setup: MCF Mechanical Design Wing has been setup with advance design capabilities; 3 Verticals in Design wing i.e. Shell design, Bogie design and Interior design and equipped with Workstations with NX 12.0 & PLM software, FEA & Train/coach Dynamic simulation (SIMPACK software). CAD software is used for design of all coaches and its components with all the relevant EN / ISO specification available with MCF design wing. Digitization of drawings of various LHB coach variants (3D parametric model) is being carried out.
2.0 Developments and Achievements :
2.1 SMART coach
First smart coach of Indian railways [NCR -18155/C (LWACCN)] manufactured at MCF furnished with Passenger Information Coach Computing Unit (PICCU) with various amenities like PAPIS, CCTV surveillance, OBCMS (Onboard coach monitoring system ,Water level indicator, Control of HVAC parameters and digital destination board ,Wi-Fi & Infotainment ,automatic fire detection and alarm system has been turned out on June,2018. It has started giving its preliminary report and going to eliminate on line failure and will facilitate preventive to predictive maintenance and thus will result into saving in terms of reduced maintenance and less down time and thus proposed for regular adoption. With the introduction of diagnostic system and also regular fitment of fire detection and alarm system, it is possible by Indian Railways to adopt superior technology such as articulated bogie and tilting coach technology which will facilitate reduced forces and stresses on fixed infrastructure (track and bridges) and will improve comfort and reduce the journey time on existing infrastructure. In fact, this will be the least expensive option for the existing infrastructure.
Second Smart coach NR 182737 (LWACCN) has been flagged off by Hon’ble Prime Minister on 16 Dec’18.
SMART Power car:
First of its kind power car has been rolled out by MCF which has been developed with M/s Kirloskar in Nov’18.
2.2 Review of design tolerances
In order to improve accuracy and quality of product tolerances are reduced from ±14 mm to ±2 mm in Body shell, Under frame, sidewall & roof
2.3 PU based Wet on Wet application on exterior painting
In wet on wet painting system after application of surfacer wet on wet top coat applied. In this process; No primer application, reduced painting cycle time and 6 years warranty for gloss and colour retention. It results in improvement in painting system to achieve high production. The painting will be done as per specification no. MMDTS 18034 Rev-04 and complete cycle time for painting of coaches is about 30 Hrs.
2.4 Export coaches:
