Week 07/04 ~ 07/08

1.     Subjects

A.     Small Scale modeling and Manufacturing

B.      Suspensions of Half Scale

2.     Goals

A.     Make more stable system (Stability and Torque balance)

                         i.         How to make the bogie

B.      Prevent vibration when moving follow the inclined track and corner

                         i.         Vertical / Horizontal

1.      Using 5 suspension is composed of Spring and Damper

2.      Making independent system for bogie and cabin

-       The reason why we make this independent sys is that suspension between bogie and cabin can prevent vibration from moving.

-       Difference between Using only two suspensions with dependent sys and applying independent sys.

n  Vibration can’t be delivered to the cabin directly because of two parts of suspension sys.

n  However, using one suspension part can’t avoid the connection between bogie and cabin. So vibration couldn’t effectively be reduced.

-       In these reason we choose two independent suspension system. It would be helpful to control the pose of cabin. 

3.     1^st week development progress situation.

A.     Making each drawing and 3D modeling of small scale.

2^nd week (the other team arrived )

B.      Improving 3D modeling of the small scale

 

4.     Problems

A.     For small scale

                         i.         We need to divide track into three pieces.

                        ii.         Can’t find the parts to fit for small scale.

 

B.      For half scale

                         i.         For maintaining posture of cabin we need to apply active suspension.




=======================================================================
We found our newly designed work has some error... we thought using current system is more time-efficient way.

so we gonna change our direction of work and we decided to use the current active suspension system.

but we will work on improve the lower part of the system: vertical directional suspension.

It includes two mountain bike suspension

we gonna change the mechanism of that to complement some disadvantages current active system has.

Details of our new work will be posted next week.
