<\/p>\nHi Support, <\/p>\n
Few questions on bolts in the 2022R2 release. <\/p>\n
The new Assign tool allows you to apply bolts to your models automatically. <\/p>\n
In the below image it mentions ‘Automatic pre tensioning’ what does this mean? <\/p>\n
If I then add a pre Bolt preload is this automatic pre tensioning ignored? Just wondering if it will then overtighten if it is not? <\/p>\n
With the Bolt Pre Load you can specify a ‘Torque’ value. I presume this is the torque required to tighten the bolt? <\/p>\n
It mentions torque co-efficient is this friction co-efficient and the table in this document could be used as a rough guide – (Link removed due to Forum posting guidelines) <\/p>\n
If you have used the Bolt tool to assign bolts it automatically allows you to search for similar holes. <\/p>\n
In the image circled it says you can do this for adding preloads? <\/p>\n
Edit: Worked this out all the bolts can be selected in the structure tree to allow preload to be applied to all without having to go through manually one by one. <\/p>\n
Last question is on washers. When using the bolt tool it gives a defaults washer ‘head’ diameter which cannot be changed. If I was using a larger washer I may see different results in reality as a load maybe more spread. Do you have any thoughts on this or is that even if we could change the size it would not effect the results seen? <\/p>\n
