Subsystems

Creo First Model

Arm

Arm

The armature subsystem contains many pivotal structures such as the strain arm and attachment points for force application and counterbalance.

Blocks will be built primarily from Aluminum 6061 and pretty much be intertwined with every subsystem.

Mounting

Mounting

The Mounting Subsystem consists of the mounting for our armature system to the base team's reciprocation system. It also contains the subsystems for movement in the X axis and supports and raises the armature.

Counterbalance

Counterbalance

The Counterbalance system is what allows the force application to be applied in the amount specified by negating the weight of the system with a weight on a threaded rod on the opposite end.

Force Application

Force Application

The Force Application system will consist of weighted masses with a center hole placed onto a rod.

The weights will be locked down with a nut to ensure they do not move. The nut is included with the counterbalance.

Sensors

Sensors

Strain Gauges will be used to measure the friction force that is outputted by the system. They will be placed along the strain arm. Wires will run along the top of the system and out at the balance fulcrum.

Engineering Analysis

Engineering Analysis

Iterative activities to demonstrate feasibility, including assumptions you made in your analyses or simulations. Have you completed sufficient analysis to ensure that your design will satisfy requirements? Have you included all usage scenarios in your modeling?

Drawings, Schematics, Flow Charts

Describe your design in enough detail for someone else to recreate it. Have you included assembly plans and user manuals? Your team may want to create separate nodes and/or directories for CAD, Schematics, or Software

Currently using CAD folder.

Bill of Material (BOM)

With your guide, consider whether/how to distinguish between your team's build and what would be required for someone else to replicate the design. This means accounting for things like donated items and machine shop time. Do you need to account for future larger-scale production plans? Have you captured sourcing for all parts, including price and lead time? Has your customer/sponsor approved these purchases? Does your total budget account for things like prototyping and shipping, which are not part of your final product but generate real costs? How do you propose to test that your design will work as expected?

Risk Assessment

Updated assessment from Systems Design or link to other location. Have you driven the likelihood and/or severity down as you worked through the details of your design?
