Need help finding planar multibody systems!

  1. Oct 1, 2009 #1
    For my assignment I have to model a multibody system. I'm having a hard time trying to find a system that isn't overly difficult or easy. Right now I'm thinking about modeling the mechanical system of a mountain bicycle.

    Do any of you guys have any ideas? Oh and there needs to be a spring-damper element.

    Here is the assignment:

    September 22, 2009
    Due October 6, 2009

    Select a planar multibody system and find the necessary data for the system (the data could be estimates).

    (a) Model the system using the point coordinate method.
    (b) Revise the Matlab programs Point_Coord to evaluate the constraints, the Jacobian matrix, the right-hand-side array of accelerations, the array of forces, and the mass matrix.
    (c) Prepare a short report describing the system, showing the primary points, constraints, etc.

    Your work will be graded based on the clarity of the report, complexity of the system, correctness and the complexity of the model.

    The complexity is based on:

    Type and number of constraints
    Presence of spring-damper elements
    Approximated mass versus exact mass distribution
    The actual system itself (what does it do)
