Project 2

Aim: To Create Sliders for the Undercuts present in the CPU Fan Case. Undercuts: Any indentation or protrusion that prevents a part from being ejected from a mold is known as an undercut. It is a quality that the cavity and core by themselves are unable to capture. Because it is die-locked, the part cannot be ejected from…

Keeping end extremity at 30mm (from connectors end) Flow chart of wiring and harness assembly Identifying Harness Assembly components Defining all Harness components…

Objective: To download the P-Clamp CAD data and define it as Electrical Support in the Electrical Part design workbench and define the necessary electrical properties. To download the Back-shell CAD data and define it as Electrical Back shell in the Electrical Part design workbench and define the necessary electrical properties.…

Introduction Electrical Distribution system (EDS) and Wiring harness 1) Electrical Distribution System: It involves physical and logical schematic architecture development, power distribution, design of wiring harness of given electrical system. The physical location of all electrical components placed in the vehicle can…

Roof Design The conventional task of the roof panel is that of compartment shielding and connection of body sides, front and rear roof cross members. In the case of roll over, compartment integrity is provided by the compartment frames. Any roof panel material requires braces to prevent panel flexing and vertical waviness,…

Benchmarking Benchmarking has been unanimously accepted as an effective performance and productivity improvement tool by auto companies. Benchmarking can be used effectively as a tool to compare product attributes, quality attributes, operations, and processes. Benchmarking involves a structured comparison between similar…

Underbody Coating A vehicle's underbody is subject to wear and tear caused by elements such as stones, potholes, muddy water. To prevent this from happening a coating is applied to the underside of the car body known as underbody coating. This shields the underbody from rust and the debris coming off-road. Pre-treatment…

Section modulus Section Modulus is a geometric property used to calculate the bending stresses in a structural member. It is defined as the ratio of the moment of inertia of a section about its centroidal axis and the distance of the extreme layer from the neutral axis. Section modulus, S = I/y                    …

Fender Design Fender is a closure component, closing the engine compartment from the left and right side of a car. During the motion of the automobile, the wheel picks up a sand, mud and small particles and throws it inside the car and fenders will be helpful in preventing them. Two types are Fenders are designed, Full…

Fender Wheel Arch Calculation Wheel Arch is the semi-circular part of the fender located above the wheel of the vehicle. The wheel arch area of the fender is usually designed as cover over the tyre to stop any stones or debris, dirt, and sand from getting thrown into the vehicle. Different regions have different wheel…

Hood design The hood is a hinged cover that encloses the engine in a front engine vehicle whereas it acts as a door for the front trunk in a rear engine vehicle. Hood opens to allow access to engine compartment. Hood is an important component of a vehicle considering the frontal crash and pedestrian safety requirement.…
