Internal Geneva Mechanism
Aim- Modelling and motion analysis of an internal geneva mechanism
Geometry modelling:
driven wheel-
Driver wheel-
complete assembly of the parts -
-------------------------------------------------------------------------------------------------------------------------------------------------------------------
Motion analysis simulation setup-
1.
1)A motor at 10 rpm and 20 rpm accrodingly is setup to the axis of the driver wheel.
2) contact forces are established as follows-
driver wheel pin - slot of the driven wheel.
3. Material of both parts is selected a steel dry
-------------------------------------------------------------------------------------------------------------------------------------------------------------------
Contact force between the components at RPM-
Angular velocity of the driver wheel without precise contact-
Angular velocity of the driver at 10 rpm and precise contact(60 fps)-
The velocity initially is at 600 rad/sec and exponentially comes down to 60 rad/sec at 1.6166666seconds
Angular velocity at 20 rpm and precise contact(120fps)-
The angular velocity plot is similar to that of 10 rpm as the frame rate have been also increased by 2x.
