Design of Roll-Off Trailer
My team (of 4) and I designed a 15000lb capacity roll of trailer on SolidWorks as a part of semester long course deliverable for MEEN 632 - Computer Aided Engineering.
​
Following requirements were set for the trailer:
​
CHASSIS:
-
Frame was analyzed for bending at different loading locations of the container placed on the trailer
-
Hinges, pins and shafts were designed for various failure modes - Shear, tension and bending.
-
The chassis was designed with a fos of 2 on yield strength of the material
​
Chassis subassembly was designed to have following specs:
-
S8x18.4 - chassis long beams
-
6x6x0.5 square tubes - bed frame & chassis cross beams
-
Five - Ø2’’ hinges at bed-frame connection
-
Ø2.5’’ high strength SS pins for cylinder attachment
-
Ramp for loading and unloading operation
Chassis sub-assembly
Container self locking mechanism
-
A spring loaded self locking mechanism was designed to hold the loaded container in place.
-
When the pin on the face of the container would slide in the cavity, the locking arm will rotate upwards allowing the container pin to sit in its desired place.
