Motion studies; Hands - On Exercises

Use the base assembly to develop relationships required for building a mechanism that

contains links, joints, which attach to fixed bases. The base will be selected to add a

grounded pivot point.

The bases will be adjusted to various positions and relationships to practice the

formation of different combinations of linkages to perform minimum and maximum

reach, of attached components.

Download Exercise Folder

Select the folder that contains assemblies and component’s that will be used to build an

assembly for each example.

Motion Exercise 1-Link collision and min, max travel

Open the assembly entitled ArmArticulation.asm to perform motion analysis of the

mechanism.

Objective: use the motion environment to find missing minimum and maximum travel

between linkages that form a working envelope.

Motion Exercise 2-Slot Pathway

The slotted arm can be used for the determination a link that can be designed to attach

to the pathway of the cavity.

Objective: use the grounded bases to develop a link that rides along the path of the

slotted arm. Once the new link is created find the maximum and

minimum travel of the system. Create in place the new missing Arm

and a pin that rides the slot.

Motion Exercise 3-Cam Follower

Use the cam follower to develop cam relationship to the elliptical Cam

Objective: create a Cam relationship that will permit a roller to follow the perimeter of

the element.

Exercise 4-Cam follower & slotted link

Use the base parts to create the motion required for the cam and slotted arm

Objective: create a Cam relationship that will permit a roller to follow the perimeter of

the element. Develop a part that will guide for the link that will maintain parallel

orientation to the base.

When work has been completed save the AVI movie for each of the mechanisms so

they can be reviewed. Do not email them.
