CAPSTONE PROJECT

CAD of Test Platform

Bearing Test Platform, Sponsor: JPL Tribplogist

Design a testing platform such that JPL may characterize roller-element bearing (REB) performance for NASA applications

Objective: Produce a testing platform that can be mounted to and fit within the project sponsor’s tribometer.

Actions:

Developed overall system architecture and performed basic hand calculations to inform final platform layout
Designed and performed interactive FEA in SolidWorks on base plate assembly to minimize deflection while reducing weight
Created mounting hardware to simplify assembly and platform mounting

Results: Platform design meets size, weight, and deflections requirements developed with the project sponsor.

Objective: Create a structure to support the test bearing and transmission while rotating under expected testing loads.

Actions:

Responsible for the initial design of sub-assembly to support and turn test bearing prior to identification of COTS spindle. Supported verification and integration of COTS spindle.
Specified COTS bearing to support lower transmission
Created support blocks the hold COTS Spindle and lower transmission under maximum loading conditions
Specified components to properly constrain lower drivetrain components on a rotating shaft

Results: Designed completed consisting of components selected to perform under expected operating conditions
