CRITERION of EFFICIENCY THAT TAKES into account ECOLOGICAL SAFETY of PROCESSES of Reshape of SHEET DETAILS of TURBO-ENGINES

V.V. Dragobetsky, V.M. Shmandiy, O.V. Kharlamova

The basic distinctive features of sheet details of turbo-engines of aircrafts are considered. Grounded, that task the choice of technology them reshape is a variant and specifies the far of the varied values of parameters of technological process. It is set that at the decision of tasks of optimization of processes of plastic reshape it is necessary to take into account a few aims which contradict one to other. The proposed criteria include generalized expectation value of the damage inflicted. The indexes of ecological safety part on determined and casual. The probabilistic parameter of estimation of the inflicted harm is entered by the concrete type of harmful action. Comparison of harmful actions in the performance of welding and explosive works.

Key words: ecological safety, criterion of efficiency, aviation engines, credible parameter ecological danger, plastic reshape.
