Week 6 (9/28 - 10/5)

Week 5 (9/21-9/28)

For the week of September 21 - September 28 we basically worked on our presentation. Since this is our first presentation of the year we want to make sure we do everything right and spend a lot of time on it. This includes doing more research, the calculations, and any drawings we want to put on the presentation.

Active Suspension Week 4

We have updated our Gant Chart to include presentations, so we can start preparing for them.

In addition we observed a video of  an active suspension of a formula 1 racing car, which we modeled our current design after it. The video can be seen here:

We are also in the process of constructing the free body diagram for our system to determine the equation of motion. 

Active Suspension Team Week 3

Following the sketch we provided in our previous post. To demonstrate the idea we have included a couple videos as proof of concept. 

Push Rod Suspension:

This video shows how a mechanical push rod suspension is used in a road application. We took this idea and thought it could be adapted to be used in the active suspension for the pod car. The advantages of the push rod suspension system are that they are compact and serviceable.

Four bar Crank Rocker:

This video is to show an example of a crank rocker mechanism. This could be used in a mechatronic system design to level the cabin as it ascends or descends. This system has the advantage of being simple to program and simple to build.

Proposal Narrative:  The suspension system must isolate vibration in the vertical axis due to the bogie wheels rolling against the overhead track.

Design Requirements:

1.

The cabin must be must maintain a horizontal angle (parallel with respect to ground). Max Angle of incline/decline assumed to be 17 degrees.

2.

The suspension system should constrain the movement of the cabin such that there are only

two degrees of freedom (2 DOF).

3.

A damping system will be needed to isolate the cabin from vibrations and oscillatory motion.

4.

The suspension system must be capable of self-leveling the cabin to the station platform.

5.

The suspension system must interface to both the cabin and the bogie.

6.

All components and hardware must have a sufficient safety factor associated with the forces

and stresses imposed by static and dynamic loading.
