Determination of minimal resource for the base machines components (by the example of dipper stick of full-revolving shovel)

摘要

Application of minimal resource of machines base elements instead of "-percent resource is grounded, correlation link for transition ratios between selective distributions and distributions of strength and loading parameters is obtained. By the example of dipper stick of full-revolving shovel resource calculation from the Veller-Serencen-Kogaev formula by Monte-Carlo method and four methods of minimal resource calculation are compared. It's stated that at the minimal resource calculation error is from 2% to 19% at totalities volume 10{sup}3-10{sup}6.
