Hey GregLocock, thank you for your comments!

3D Dave, theoretically you are right...but actually I have to take action and know what I do for avoiding a failure... after all I am responsible for that jig.

Thank you all for giving me a starting point and tips. As for the question why I don't include the true tested body in the analysis, there are 2 reasons: 1. The tested body is still being designed by another group in the company I work in, and for making the design phase shorter- there is a...

Can someone please answer my principal question what is the right method to analyze my case without concentrating on the schematic pictures that were meant to generally illustrate.

You are right, but I am not sure you answered my question :/

Hello, This is the first time I design a fixture for a vibration test, so I guess my question might be basic to most of you. I have an assembly that should be carried by a certain platform. The Vibration Spectrum of the carrying platform was measured and is given as part of the requirements. As...

Thank you Sparweb, very useful information!

Hey Sparweb and thank you for being care and giving advices. Is there a guide/article etc. that lists which compounds/lubricants contact with titanium is forbidden (and perhaps learning why and what are the risks of using these materials)? I have some manufactured titanium parts with internal...

Thank you all. I will use titanium screws rather than Aluminum. I am still not sure about titanium seizure risk. Try to figure out through some articles.

This is for a carried device by an aircraft

After reading all of your advices I understand that titanium is preferable. I still have 2 uncertainties regarding using titanium: 1. Is there a risk of cold welding when using titanium bolt and titanium nut without any special coating?According to this website, there is a risk of cold welding...

Do you have any recommendation to a coating that can prevent galling? I have in addition to apply a locking element such as patch.

Hey, Do you have a known manufacturer of titanium screw? Do you have a recommendation to an anti seize compound?

Hello everyone I have to decrease weight in my assembly. One of the suggestions is using aluminum bolts rather than using low-medium carbon steel. I checked if it's possible when considering strength, and it's indeed possible if I increase the bolt's size (and I still lose weight). The point is...

Hey, the loads are in both directions. It means the joint experiences tensile and compressive force. About the tolerance in preload when using the traditional torque meter - I am also worried about it and I am sure the suggested solution given above is excellent. Now is the difficult part -...

Thanks (itsmoked) for replying and explaining your choice :)

desertfox, the external load for each bolt is estimated to be 1500N.

itsmoked thank you very much! I didn't know about this kind of instrument. Do you have any experience with this specific company? Which company is the leading one in this field?

desertfox, I am not sure I understood your last question :)

Hey, I am going to give you an additional information that was achieved prior to dealing with the thermal effects. I started by FBD for calculating the required force (with safety of factor) the bolted joint should bear - 2450N per bolt. I checked that the ULTEM 1000 stress isn't above 40 Mpa...
