Until recently my facility has had third party support for developing and managing our test lab but the company is going out of business and we are attempting to take ownership of our own lab software and equipment. Our stands test various fluid components (pumps, valves etc.) where we monitor...
Hello All,
I have a customer who wants me to evaluate the pressure pulsation of our new pump design and this I have never done in detail but told them I would attempt to do so and learn in the process. Only in one previous application have I been exposed to such a topic so hopefully someone...
Hello,
I perform random vibration analysis for a small company utilizing cast aluminum housings which are typically piloted into to a gearbox of some sort and mounted via a bolted mounting flange. A recent housing has the main body outside of the gearbox and is mounted via a bolted flange...
Hello,
I am performing a random vibration analysis and test on a part which pilots into a test fixture and mounts via a bolted mounting flange. The part has various masses attached to it which created an undesired overhung mass system but similar designs have worked for us in the past and this...
During various types of static analyses I am often asked to try different materials along with geometry variations. I have become familiar with design studies to help automate the proposed changes in the design but I have yet to find an easy way to change materials in between analyses without...
I have recently had some vibe and shock testing performed by a local test house and have ran into a question of test tolerance and the likelihood of over-test/under-test. Up to this point my experience deals with random vibration testing and classical sawtooth impulse shock testing; however...
I am trying to save time and save a copy of a part (and therefore its associated drawing) with a new name to keep a similar drawing scheme. What I have noticed is that when I save the part to the new name a new drawing is created with the new name but it still references the old part. Does...
Hello,
I have been using pro mechanica for a couple of years now and have been dealing primarily with Dynamic Time and Dynamic Random analyses and would like to know if there is anyone out there that is utilizing the stress error fringe plots available in WF5 and Creo 1.0? The analyses I am...
I am trying to get a feel for how Pro/M is handling the fastener idealizations that I have in place. I am using advanced fasteners with an applied preload and contacts interfaces to achieve a proper assembly clamp force. My issue comes in with the following statement taken from PTC's suggested...
Hello,
I am trying to run a random vibration analysis in pro/mechanica and have ran into a question about mass participation factors. I understand the need for a high mass participation factor to determine global modes over local modes but I do not understand why an increased number of modes...
