Report on assembly of chopper

Title of the Project

Assembly of american chopper

Objective

to make a model of american chopper. make parts and assemble them in solidworks assembly. render the assembly and parts.

Introduction

This project explains the designing of American chopper using the SOLIDWORKS. From sketching and modeling parts to final rendering of the assembly to give a photo realistic view, everything is done from scratch.

Design methodology/approach (To be explained with the help of Flowchart)

Overall flowchart -

(1)sketch - (2)part - (3)assembly - (4)render

(1)Sketch -

use line, circle, arc, spline, slot, trim entities, convert entities, offset entities, mirror entities, linear sketch pattern, blocks , dimension etc. to make a fully defined skectch.

(2)Part -

use features on the drawn sketches, to make a part. use features like extruded boss, revolved boss, swept boss, extruded cut, revolved cut, swept cut, fillet, pattern, mirror, reference geometry, curves, split etc. to make parts.

(3)Assembly -

import parts one by one in an assembly file and add constraints over them to align them into an assembly. use mates like coincident, tangent, distance, limit angle, width, parallel, angle, concentric etc. to align and fix parts. mirror them if necessary.

(4) render -

we use solidworks add-in Photo View 360 to render the image. when we want to see how the CAD model looks in real life with all the nuances of light playing on its surface, we go to render a model.

there are numerous setting options in rendering. you can add decals, which can be seen in the models attached with this report as well. appearances can be edited. so can the scene in which the CAD model is to be placed.

we see integrated previews to have a wuick look on how the model behaves in conditions to lighting adn overall look. preview windows does a similar job. final render shows us how the image is going to be after wverthing is kept in check.

when we want to select a specific region to render, we use render region option. ther are a lot of choices offered by SOlidworks to select the lighting conditions, camera positions, adding decals on thg decals on the parts etc.

there is an Options setting where we choose output image size, render quality - good, best, maximum; bool options, contour/cartoon rendering, direct caustics, network rendering and more.

if the render is expected to take a lot of time, we can schedule it. also recalling last render is one of useful options to play with.

Description (Need to explain tools/ Features used while designing) along with the images of Part files

Appearances: defines visual properties of the model including colour and texture. they do not affect physical properties which are defined by materials.

every material is a assigned a default appearance.

Boss Extrude: extrude sketch from plane.

Extrude cut: cut a solid using a sketch.

Fillet: applied on sharp edges to make them smooth applying fillet radius.

Lofted Boss/Base: feature used to achieve Complex Shapes. interpolates surfaces between various cross-sections of a model .These cross-sections can be sketches ,faces ,or edges.

Split: split single solid part into two solid parts with help of two or more parts.

Dome: make dome shaped extrude including elliptical dome and other options.

Shell: make to solid hollow part.

Combine: integrate two or more solid parts which intersect each other.

Chamfer: make a sharp edge or corner slightly tapered.

Linear Pattern: creats pattern in a single direction specified.

curve Driven Pattern: pattern is amde with input as curve.

Circular pattern : pattern is made in a circular orientation. inputs could be radius and number of instances.

Revolve boss base: solid is made from a sketch, as a result of revolve.

Revolve cut: a solid is cut from a revolved sketch.

Sweep: This feature is used to sweep any kind of fully defined sketch along a the path.

Loft -. Loft surface is used to make loft in between two profiles along with guide path.

Knit surface'. Knit surface is used to knit the two free edges or open edges of the surfaces together. it reduces the gap between the two edges of the surface.

Surface Trim: used to cut away material from a surface.

Projection curve: two different curves in 3D can be combined into one resultant cureve using this.

Blocks- readily available redundant sketches used for reference.

Trim entities : it is used to trim the unwanted lines or extended entities in the sketch.

Appearances :An appearance def ines visual properties of the model including colour and texture. Appearances do

not affect physical properties which are defined by materials . every material is a assigned a default appearance.

following are the attached images of parts.

decals, lights and camera area dded and then the rendering is done.

min of five screenshots of the Assembly Model in the report. (For eg:-Front View, Side View, Isometric View, Camera Setup View, and the Top View)

the above image is the camera view iamge.

process of assembling parts:

after all the parts are made, they are imported into an assembly file one by one.

assembling requires imposing constrainsts on the parts, constraints like coincident, concentric, distance, limitAngle, Width, parallel, tangent, mirror

these constraints enable us to assemble the parts in plave so that every part maintains a proper spatial arrangement with respect tot the chassis, which is finally fixed.

then teh rendering process starts.

Attach Detailed Rendering Images of Assembly (If possible you can do the rendering of each part and attach snaps of same in report.)
