ELECTRICAL CONTACTS WITH HIGH DENSITY FOR STRONG CURRENTS, MADE BY POWDER METALLURGY

 

Electrical contacts for strong currents by infiltration after sintering, was not satisfactory because the final density is much higher (11,100 kg/m3) and porosity is much lower (10.85 %). The infiltration after sintering contains: powder mixture preparation (W – 52 mass %, Ni – 2 %, Cu – 46 %, zinc stearate – 0,7 %  – 7 g), homogenization, pressing (4,5 MPa), sintering (730 and 780 oC). The green density is almost constant, with an identical porosity of the first after the end of the process (14,28 %). By infiltration the density increased drastically (10,832 kg/m3), its variations were increased also and porosity decreased (at 10.85 %). The attained density is not sufficient for electrical contacts work (11,100 kg/m3), but it is closer. Way to improve density: pressing, sintering, and repressing (10,700 kg/m3).

BRAZING OF NICKEL-ALUMINIUM

 

The brazing between nickel and aluminium plates is a very sensible process being influenced by type of used materials and by brazing devices which maintain in contact the metal plates. These brazing devices have a very important purpose, their pressure affect directly the capillarity force. If the brazing devices are too tight (like 7 bar pressure), the filler melted metal escape from the grip, causing presence of defects in the joint; if the brazing devices are not tight enough (like 5 bar pressure) the capillarity forces become weak, allowing the voids inside the joint. Therefore, it’ is optimal for a nickel-aluminium brazed joint without defects a 6 bar pressure, created by brazing devices,

THE VARIABILITY OF MORPHOMETRICAL ELEMENTS FEATURES COMMON DEER TROPHIES IN THE CATCHMENT GURGHIU

 

The stag (Cervus elaphus) is one of the most important species in our hunting ground areas. In the socio-economic context of our country, the common deer populations have a great significance taking into consideration both the financial benefits obtained by practicing hunting and its important niche role in the mountain and pre-mountain ecosystems. In present paper we have studied the variability of the morphometric characters of stag trophy at different ages. In order to achieve the proposed objectives, the carried out study analysed a number of 29 trophies.

The assessment of trophies was made by applying the CIC methodology and by respecting all rigors related to characters measuring and use of tools.

The data were statistically processed by calculating the variance, coefficient of variation and establishing the correlations between the morphometric characters and exposing the regression equations of these correlations.

The authors intend to study how the human bio-field responds at a nonphysical stimulus. More precisely, what happens when a person, using special techniques, retire the energy from the exterior of the body through the interior, for 2-3 minutes? The authors find out that this procedure was interpreted by the energetic body as an aggression leading to a state near illness. The subject stopped his actions, not to create damages to the entire human being which could eventually require a treatment. A very important observation of the authors is that during the experiment it was noticed a tendency of hysteresis for the human being, phenomenon which the authors decided to study in the future.

THE INSERT OF METAL IN THE ROTOR BLADE OF

THE LOW POWER WIND TURBINE

 

Attachment of the wind turbine rotor blade is made by a metal structure, that provides a rigid mounting and precise positioning as accurate as possible to the calculated direction angle of incidence of the air flow relative to the blade profile sections. The mechanical strength at static load for the blade is within acceptable limits even without metal insert. In real operating conditions, the wind gusts have the effect of a dynamic load upon the blade and the base material, fiberglass reinforced polyester (FRP) is subjected to fatigue stressed. This leads to micro cracks in the resin and gradually reaches the blade breakage. Therefore the recessed fitting area of the blade, which is an aerodynamically inactive area, must have a metal structure with maximum adhesion to FRP of the blade structure. The shape of this structure, the way of insertion into the interior of the blade, the depth of penetration, are issues which will be discussed in this paper.

Designing and testing the coupling solution of a trailer at the hook of utility all terrain vehicle CF MOTO 500-2A

 

All-Terrain Vehicles are today quite popular and often known both as entertaining systems as well as utility equipment. The scientific paper shows a small contribution to the design and implementation of a practical solution for coupling the trailer to the ATV tow. There was used a dynamometric sensor in order to measure the inertial forces during braking process in various conditions of driving the ATV CF MOTO 500-2A, considering all the time accelerating and decelerating manoeuvres in the case of trailer towing, when a traction mass is placed on the vehicle’s hook, due to the attached trailer. The importance of studying the kinematic and dynamic aspects of ATV’s driving process resides in significance that the trailer inertia force has on the road train during some driving manoeuvres of cornering, decelerating and accelerating.

research REGARDING THE INFLUENCE OF ROUGHNESS ON PERFORMANCE OF AN INTERNAL COMBUSTION ENGINE

 

The present paper presents the study of the intake pipes surface roughness and its influences on the performance of an internal combustion engine. The measurements of the roughness were made experimentally, and the influences were studied using three simulation software: AVL BOOST (2013.1), GT Suite (7.4.0) and WAVE (2014.1). In order to obtain conclusive results, the same engine (Opel Astra F engine type C20NE) was simulated in three software, using the old type of materials for the intake pipes (forged cast iron) and the newer versions of materials (plastic). The data from all simulations were extracted, managed and accurately inspected and interpreted. The main conclusion of the paper is that the surface roughness of the intake pipe has an effect on the power of the internal combustion engine, not only because of the weight, but also the flow is improved. The same conclusion was obtained from all software.

Experimental researches of the operational problems concerning the power supply system for the ACID battery from Dacia solenza

 

The present paper express in available technical terms and means of an experimental research concerning problematic aspects of the power supply system from Dacia Solenza 1.4 MPI vehicle in relation with liquid acid accumulator on board.

After cold starts of the internal combustion engine some unusual engine speed fluctuations occur which destabilize the proper operation for the first minutes in cold running of the vehicle.

The worst case scenario is when engine stops suddenly in the middle of a street junction without any previous major signs and as a bonus without any possibility to restart immediately. Analysing the power supply system and differential potential allows the researcher to gain some significant insight in the process and to develop important knowledge (as know-how) and arguments in solving the problem once and for all.

The development of present research aims toward the goal of pointing out the symptoms and problematic aspects related to the power supply and management systems on vehicle Dacia Solenza.
