Calculating Mass Moment of Inertia in a Two Stage Planetary Gearbox

AI Thread Summary
To calculate the mass moment of inertia (MOI) at the output shaft of a two-stage planetary gearbox, specific gear parameters and physical geometry are crucial. The provided torque and input speed alone are insufficient for a complete calculation. The discussion highlights the importance of understanding the gear arrangement and dimensions, as these factors significantly influence the MOI. Additionally, the need for MOI in the context of the gearbox's application remains unclear. For accurate calculations, referring to dynamics resources and formulas is recommended.

hi everyone,
help me, To calculate the mass moment of inertia at output shaft with respect to input shaft in the two stage planetary gearbox.

Torque at input = 15 Nm
input speed = 1440rpm
stage I
zs=14
zp=23
zR=61 fixed
stage II
zs=21
zp=40
zR=102 fixed
 
Engineering news on Phys.org
The mass moment of inertia, as I understand it, depends on things like the actual physical geometry of the gears. The information you have given is insufficient for such a calculation.
 
can explain the method or formula for finding the mass moment of interia?
 

Thread 'Bubble formation in 4 mm gap vessel'

How did you find PF?: Via Google search Hi, I have a vessel I 3D printed to investigate single bubble rise. The vessel has a 4 mm gap separated by acrylic panels. This is essentially my viewing chamber where I can record the bubble motion. The vessel is open to atmosphere. The bubble generation mechanism is composed of a syringe pump and glass capillary tube (Internal Diameter of 0.45 mm). I connect a 1/4” air line hose from the syringe to the capillary The bubble is formed at the tip...

Thread 'Physics of Stretch: What pressure does a band apply on a cylinder?'

Scenario 1 (figure 1) A continuous loop of elastic material is stretched around two metal bars. The top bar is attached to a load cell that reads force. The lower bar can be moved downwards to stretch the elastic material. The lower bar is moved downwards until the two bars are 1190mm apart, stretching the elastic material. The bars are 5mm thick, so the total internal loop length is 1200mm (1190mm + 5mm + 5mm). At this level of stretch, the load cell reads 45N tensile force. Key numbers...

Thread 'Find 3D Printer & Software Resources for Prototype Creation'

I'd like to create a thread with links to 3-D Printer resources, including printers and software package suggestions. My motivations are selfish, as I have a 3-D printed project that I'm working on, and I'd like to buy a simple printer and use low cost software to make the first prototype. There are some previous threads about 3-D printing like this: https://www.physicsforums.com/threads/are-3d-printers-easy-to-use-yet.917489/ but none that address the overall topic (unless I've missed...
