20-66 SISTEME MECANICE DE ADĂPARE UTILIZATE ÎN ZOOTEHNIE

MECHANICAL SYSTEMS USED IN ANIMAL DRINKING
Any species of animals in animal breeding farms needs one ore more
types of drinking troughs (depending on the operating system) that would be
specific to its biometric characters, microclimate, and must provide physical and
social comfort. Drinker types used determines the surface that animals should
have around them. The importance of knowing the animal needs stems from
the fact that accurate information on drinking troughs can be designed to be
more efficient, more economical, more reliable or that may be more ergonomic
for the animals and thereby increase the production by a few percent, which in
the current economic conditions can mean a lot.

23-58 ANALIZA NUMERICĂ A TENSIUNILOR REMANENTE DINTR-O PIESĂ TURNATĂ

NUMERICAL ANALYSYS OF RESIDUAL STRESSES
IN A CASTING
In this paper, the authors study the evolution of the residual stresses
that arise in a water drinker (used in animal husbandry), during casting. The
residual stresses are determined by simulation using a numerical method
(control volume).

23-59 ANALIZA EXPERIMENTALĂ A TENSIUNILOR REMANENTE DINTR-O PIESĂ TURNATĂ

EXPERIMENTAL ANALYSYS OF RESIDUAL STRESSES
IN A CASTING
In this paper, the authors study the residual stresses that arise in a
water drinker (used in animal husbandry). The residual stresses are being
determined experimentally using blind hole method.

21-96 EVOLUȚIA TENSIUNILOR REMANENTE Partea a II-a

EVOLUTION OF RESIDUAL STRESSES – PART II
Abstract: In this paper, the authors study the residual stresses that
arise in a stress lattice during casting. The residual stresses are firstly
determined experimentally and secondly simulated using a numerical method
(control volume) for method validation.
