Cel' issledovaniy – obosnovanie aktual'nogo napravleniya v sovershenstvovanii sredstv mehanizacii podgotovki neteley k laktacii. Eksperimental'nye issledovaniya ustroystva dlya pnevmomassazha vymeni neteley (UPVN) odnokamernogo tipa vypolneny s pomosch'yu special'no razrabotannogo laboratornogo stenda, vklyuchayuschego vakuumnuyu liniyu doil'noy ustanovki, iskusstvennoe vymya i registriruyusche-zapisyvayuschuyu apparaturu. Realizaciya eksperimenta s matricey pochti D-optimal'nogo plana tipa Bn i statisticheskaya obrabotka ego rezul'tatov pozvolili poluchit' uravneniya vtorogo poryadka, opisyvayuschie zavisimost' velichiny davleniya (vakuuma) v massazhnom kolokole v taktah massazha i razgruzki ot svobodnogo ob'ema kolokola, chastoty raboty pul'satora, a takzhe diametrov drenazhnogo otverstiya i vhodnogo patrubka kolokola. Analiz poluchennyh dannyh pokazyvaet, chto konstrukciya UPVN imeet principial'nyy nedostatok, svyazannyy s nalichiem drenazhnogo otverstiya v kolokole. Eto otverstie ne pozvolyaet obespechit' neobhodimyy interval izmeneniya davleniya vozduha v massazhnom kolokole v taktah massazha i razgruzki. V kachestve vyvodov v vypolnennoy rabote mozhno rekomendovat' isklyuchenie iz konstruktivno-tehnologicheskoy shemy UPVN drenazhnogo otverstiya v kolokole, a takzhe uvelichenie amplitudy izmeneniya davleniya v kolokole pri taktah massazha i razgruzki. Pri etom v takte razgruzki sleduet otkazat'sya ot ostatochnogo vakuuma i zamenit' ego atmosfernym davleniem. Fiziologicheski obosnovannoe vozdeystvie na molochnuyu zhelezu neteley mozhet byt' realizovano s pomosch'yu massazhnogo ustroystva, v kotorom imeetsya vozmozhnost' razdel'nogo regulirovaniya intensivnosti pnevmaticheskoy i mehanicheskoy sostavlyayuschih massazha.
