CTRM worker is teaching Body-Shell & Chassis (BSC) members on how to sanding in proper way with patient

Filleting chassis edges

Fillet is formed

Marking the line to leave spacing for tyre

Cutting is done

Filleting the edges

Laminating the honeycomb structure composite materials

The bushing have been tested whether it fits in or not after the drilling process

Laminating of the chassis is done

Some specific parts have been drilled to make holes

A mixture of polyester (PE) , carboxymethyl cellulose (CMC) &hardener is use to strengthen the chassis.

High-density Polystyrenes bars are fixed at the corners of the chassis to serve as frames to prevent deformation caused by bending.

Laminating is done

MMU Grune Welt 2012- Mock-Up

MMU Grune Welt 2012- Mock-Up

In manufacturing and design, a mockup, or mock-up, is a scale or full-size model of a design or device, used for teaching, demonstration, design evaluation, promotion, and other purposes. A mockup is called a prototype if it provides at least part of the functionality of a system and enables testing of a design.

(adapted from wikipedia)

Team MMU Grüne Welt had their very 1st mockup on 26th of November 2011. The team use wooden board as their base of the chassis and some wooden plank for the body structure.

Mr. Umar Nirmal is supervising team MMU Grüne Welt and give suggestion to the team during the mock-up.

The driver of the team, Joshua is testing the driving position during the mock-up.

Engine group (Ming Han & Sze Tong) are measuring the dimension of the engine in order to fabricate a frame to hold the engine.

Beautiful sparks when Sze Tong is grinding the steel bar.

The engine is fixed on the steel plate.

Transmission group is making thread for the bicycle spokes.

Vince & Chia Wei are trying to fix all the spokes to the bicycle rim.

Ping Sheng is trying to turn the steel rod into a smaller diameter for the use of steering.

Hao Jie is using Autodesk Inventor to do the stress analysis to find the suitable size for the shaft.  

Hao Jie and Wan Jvin are working together to measure the distance of the steer rod to the bulkhead.

The outline of the base of the shell is drew on the polystyrene.

Get ready to glue the polystyrene to the base by using PVA glue.

 The polystyrene have been successfully stick on the base.

The model of body is almost formed and ready

The team uses heated tungsten wires to shape it into a more aerodynamic shape.

The model is finally is formed

Layers of newspapers and polyester (PE) have been used to form the body

Hand-make body is released

Modeling the prototype with team members & Mr. Lim B.K (team supervisor).
