Ok. How do I know how many of the lower modes are important? The reason I ask is because the first 9 are well below forcing frequency. 10th mode is pretty much bang on the forcing frequency.

Can you give more detail on these major/minor axes? You need 6 pieces of information to describe an object's exact orientation and location in 3D space: 3 distances for location and 3 angles for orientation. For robotics, a rotation is usually described by the order of rotation: x - y -...

Hi, I'm playing around with ANSYS to find the modes of vibration of a structure. How do I know which are the most important modes? I understand that there are infinite modes of vibration - getting higher and higher in frequency. I'm guessing that it has something to do with the effective...

Got to do a bit more work on the problem between actual work. I calculated all of the loads and determined where the vibration is coming from. There's one thing that I can't understand for the life of me... and it's making me feel like I'm missing something very basic. I'm trying to prove to...

What do you mean by them suppressing vibration absolutely?

Machine runs at constant speed (well, minus for the start-up/shut-down which is not frequent) For vibration isolators, the simpler the better. I don't think active damping would be considered. I was looking into designing the supports for the machine to be Tuned Mass Absorbers. I cannot...

Hi, So I'm on a work term during a semester off at school (Mechatronics), and have been asked to see if it is feasible to replare some concrete plynths with steel. These are used to support a motor and, possibly, some excentrically rotating masses. My problem is that I don't really know...

Hey all, As the title suggests, I'm seriously considering taking a minor for my degree and am curious what it should be. I'm currently in second year Mechanical Engineering specializing in Mechatronics. I'm also taking co-op. I find that most engineers who take a minor do it in Commerce - and...
