Perfecţionarea metodelor de calcul al ajustajelor îmbinărilor cu strângere, alcătuite din piese recondiţionate, din componenţa maşinilor agricole

The purpose of this study is to improve the methods used to calculate the accuracy of interference fits made of reconditioned parts by means of different wear compensation materials. The given purpose has been achieved by application of Green’s functions in order to calculate the minimum permitte...
