Rubber reinforced tracks and cushion suspension are becoming increasingly common on agricultural tractors. They increase environmental friendliness, provide asphalt driving ability and allow for higher transport speed of crawler tractors, improving working conditions for the tractor driver. The crawler tracks of these thrusters have a high degree of suppleness, so a loss of stability of the rubber reinforced track on the drive wheel can be a problem when operating under high traction loads. The most effective measure to increase the stability of the rim in the mover is to increase the pre-static tension. However, high track tension increases losses in the undercarriage and stresses the undercarriage, resulting in reduced undercarriage life and loss of performance. Analytical dependencies are derived to determine the rational pre-static tension of rubber reinforced crawler tractors with cushion and blocked suspensions during start of moving and moving modes. The required static pre-tensioning of rubber reinforced tracks for Belarus 1802, 2102 and 2103 tractors is determined. It has been found that the greatest necessary static pre-tensioning of the rubber reinforced tracks is required at the maximum forces on the driving wheels of the tractor. It is shown that locking the suspension when operating the tractor with high traction loads at low speed allows to reduce the required static pre-tensioning of rubber reinforced tracks and, as a consequence, their loading. The results of this research can be used in design and operation of tractors with rubber reinforced tracks.Β Π Π΅Π·ΠΈΠ½ΠΎΠ°ΡΠΌΠΈΡΠΎΠ²Π°Π½Π½ΡΠ΅ Π³ΡΡΠ΅Π½ΠΈΡΡ ΠΈ ΡΠΏΡΡΠ³Π°Ρ ΠΏΠΎΠ΄Π²Π΅ΡΠΊΠ° ΠΏΠΎΠ»ΡΡΠ°ΡΡ Π²ΡΠ΅ Π±ΠΎΠ»ΡΡΠ΅Π΅ ΡΠ°ΡΠΏΡΠΎΡΡΡΠ°Π½Π΅Π½ΠΈΠ΅ Π½Π° ΡΠ΅Π»ΡΡΠΊΠΎΡ

An analytical dependence was obtained to determine the amplitude of vibrations of the rubber track in the span of the free branch of the tractor bypass between the supporting rollers. The process of oscillations of this type of track in the middle of the span of a free branch during the operation of tracked tractors of the brand βBelarusβ in pull and transport modes, taking into account the speed of movement, is investigated. It is shown that the resonant modes of transverse vibrations of the rubber track at the operational ranges of the tractor operation should be taken as the determining criterion for choosing the parameters of the spans of the free branch of the bypass. The maximum values of the oscillation amplitudes of such a track in the span of the free branch of the bypass between the supporting rollers for the family of tracked tractors βBelarusβ under different operating modes are calculated. A frequency analysis of oscillations was carried out and it was found that on tracked agricultural tractors with rubber tracks, a mode of occurrence of resonant oscillations in the span of the free branch of the bypass between the supporting rollers is possible. An analytical dependence has been obtained to determine the limiting distance between the supporting rollers of a tractor with a rubber track and elastic and locked suspensions according to the criterion of deducing the resonant mode of vibration of the track in the span of a free branch outside the operational range of the tractor. The values of the maximum distances between the support rollers for tractors βBelarusβ 1802, 2102 and 2103 at different suspension modes are calculated. The required number of supporting rollers is determined and recommendations are given on the place of their installation. The results of these studies can be used in the creation and operation of tractors with rubber tracksΠΠΎΠ»ΡΡΠ΅Π½Π° Π°Π½Π°Π»ΠΈΡΠΈΡΠ΅ΡΠΊΠ°Ρ Π·Π°Π²ΠΈΡΠΈΠΌΠΎΡΡΡ Π΄Π»Ρ ΠΎΠΏΡΠ΅Π΄Π΅Π»Π΅Π½ΠΈΡ Π°ΠΌΠΏΠ»ΠΈΡΡΠ΄Ρ ΠΊΠΎΠ»Π΅Π±Π°Π½ΠΈΠΉ ΡΠ΅Π·ΠΈΠ½ΠΎΠ°ΡΠΌΠΈΡΠΎΠ²Π°Π½Π½ΠΎΠΉ Π³ΡΡΠ΅Π½ΠΈΡΡ Π² ΠΏΡΠΎΠ»Π΅ΡΠ΅ ΡΠ²ΠΎΠ±ΠΎΠ΄Π½ΠΎΠΉ Π²Π΅ΡΠ²ΠΈ ΠΎΠ±Π²ΠΎΠ΄Π° ΡΡΠ°ΠΊΡΠΎΡΠ° ΠΌΠ΅ΠΆΠ΄Ρ ΠΏΠΎΠ΄Π΄Π΅ΡΠΆΠΈΠ²Π°ΡΡΠΈΠΌΠΈ ΠΊΠ°ΡΠΊΠ°ΠΌΠΈ.

HETEROSIS ASSESSMENT OF INTRA BREED TYPES CROSSING IN ONE SUMMER OLD COMMON CARPS
At the current stage of research on combining ability of displaying the heterosis effect has been a comprehensive estimated. One-summer-old common carp crosses from crossing of the Nyvkivskiy Scale and Scaleless intrabred types (βNSCxβSLC) was used. The general control method has been used for control and checking of the farming results. During conducting experiments on comparative evaluation of common carp of different origins, it is especially important to minimize the displaying of phenotypic variability, because there are no perfectly identical growing ponds at fish farms. Therefore, in our work, the method of general control was used to evaluate the productive qualities of one-summer-old fish groups. Fish productivity is the main indicator and it is advisable to evaluate the results of fish cultivation. In this case the estimation was carried out with using the index of the corrected fish productivity (i.e. without taking into account the fish productivity obtained from the Nivkovsky Scaleless common carp). It was found that crossing groups performed better than actual β 510.0 kg / ha and adjusted β 471.8 kg / ha yield. With what combining ability for heterosis was 4,4 %. In addition, the crossing groups βLSC Γ βNSΠ showed the best in both actual - 51.2 % and adjusted - 50.2 % surviving rate, while the heterosis combining ability was 3.8 %. The average mass of this one-summer-old fish, which affects together with fattening at the survival rate of fish during wintering, was the best in crossing common carp βLSC Γ βNSΠ β 49.8 g, and the corrected average mass in this group was 47.0 g and the heterosis index was at 0.6%. The obtained results will be promising for further evaluation of heterosis and will help to improve the fish productivity of water bodie
