Overview
This section breaks the design of the LifeTrac into its different systems so that the engineering analysis and design requirements can be more easily understood
Items to Address
- Basic vehicle criteria for overall vehicle design
- Load carrying capacity
- Vehicle speed
- Vehicle power
- Vehicle weight
- Arm Range of motion
- Attachment plate range of motion
- QA Plate to Bobcat Standard
- Carrying capacity of design
- Wheel drive attachment
- Load bearing capacity of shafts
- Torsion limit if shaft using single g8 bolt and 2 bolts, with 1-7/8 shaft
- Shear limit using 3" shaft with 2 g8 bolts, 1". This is for scaling analysis of bulldozer. Goal: 16,000 lb of pushing force for prototype 1 using same design with jackshaft
- Structural analysis of frame with maximum load
- Load limit of bulldozer arms based on steel structure
- Improvements
- Auxiliary hydraulic connection at front
- Floor plate
- Roof plate
- Safety screen around occupant where necessary
- Driver position
- Vehicle control mechanisms
- Field of view improvements
- Head lights
- Optimized hydraulic locations for maximum lifting capacities
- Track design
