Rainfall characteristics and probability analysis for crop planning of Samba district of Jammu and Kashmir (U.T.) India

Paper ID- AMA-04-12-2021-10916

To stabilize the crop productivity in rainfed agriculture, it is necessary to characterize rainfall with respect to amount, distribution and its dependability which is an important parameter to evolve suitable cropping patterns. The present investigation has been done to study rainfall characteristics of Rakh Dhiansar (320 39’ N, 740 53’ E, 294 m amsl), Samba district of Jammu region using 30 years (1987-2016) daily rainfall data. In this study, weekly rainfall was worked out from daily values and used for initial, conditional and consecutive dry and wet spell analysis done by using Markov chain probability. The highest rainfall received during the month of August followed by July, September, June and March with the corresponding values of the total amount of rainfall are 321.6, 317.8, 146.6, 92.3 and 63.5 mm with coefficient of variations of 48.7, 41.3, 66.2, 85.0 and 129.2%, respectively. Maximum amount of rainfall was received through S-W monsoon i.e 878.6 mm which accounted for about 77.5% of the annual rainfall in kandi belt of Samba district. The probability of occurrence of wet week is more than 35% during 24 SMW (11-17 June), thus the pre monsoon rains can be utilized for summer ploughing and initial seed bed preparations for the sowing, better germination and good crop stand of kharif crops. It is concluded that there is a need of reconsidering the cropping pattern, selection of crops, their varieties and management practices for kandi belt of Samba district to minimize the risk in crop production as inflicted by rainfall variability.

Physicochemical and sensory characteristics of red and yellow banana pseudo stem flour biscuits were studied to standardize the banana pseudo stem flour supplement in the combine for preparing biscuits. The composite of wheat flour was replaced by banana pseudo stem flour at various percentage incorporation ranges in biscuit production. Nutritional properties of red and yellow banana stem flour incorporated biscuits showed significant difference (p<0.05). Bulk density, water activity and Color values exhibited higher as a result of yellow banana stem flour. Physical properties of biscuits substituted with 30% of banana stem flours were observed significantly higher (p ≤ 0.05) value. Proximate analysis results showed higher fibre content in red banana flour biscuits than yellow banana biscuits. Water activity, hardness and colour of the developed biscuits were showing significant difference than control. Sensory attributes indicated that the yellow banana stem flour biscuits had the higher acceptability. Hence, banana stem flour proved acceptable not only in quality characteristics but also fulfills the demand of dietary fibre and is very palatable to ingest and will be one of the agreeable biscuit taste with improved nutritional properties

Determining Optimum Gear Ratios of Three-stage Bevel Helical Gearboxes for Minimum Gearbox Bottom Area

Paper ID- AMA-04-12-2021-10913

In this paper, the results of an optimization study to calculate the optimal partial gear ratios of three-stage bevel helical gearboxes are presented. The objective of the study was to achieve the minimum gearbox bottom area. To implement it, a simulation experiment was conducted. In the experiment, the influence of eight main design parameters including the total gearbox ratio, the coefficients of wheel face width of three stages, the allowable contact stresses of all stages, and the output torque to the optimal transmission ratios of the analyzed gearbox. In addition, regression formulas determining the optimal gear ratios of the second stage u2 and the third stage u3 components have been given.

Effect of Design Variables on Gearbox Bottom Area of A Helical Worm Gearbox

Paper ID- AMA-04-12-2021-10912

This study mentions the problem of calculating optimal gear ratio according to the objective function minimal gearbox bottom area. A review of an approach to the optimization of gear ratio is conducted. By using the Design of Experiment technique combined with the Minitab®19 software, we studied the impacts of the design variables on the optimal transmission ratio u2. The results received indicated that the input variables, as well as their interactions, have an important influence on the response u2. Finally, a useful regression model is proposed based on the experiment data and its reliability is confirmed through the results obtained.

Structural Design and Simulation Analysis of the Cleaning Device of the Double Frame Plate Combine Harvester

Paper ID- AMA-04-12-2021-10911

In order to solve the problem that the crops with relatively high humidity are easy to accumulate on the shaking plate, this paper designs a cleaning device. The cleaning device comprises a first frame plate, a shaking plate, a second frame plate, a sieve body, and a driving mechanism. The shaking plate is mounted in the first frame plate and is connected to a shaking device. The second frame plate is connected to the first frame plate through a crank mechanism. The sieve body is mounted in the second frame plate. The driving mechanism is connected to the shaking device and the second frame plate, and configured for driving the shaking device to cause the shaking plate to shake and driving the second frame plate to cause the sieve body to perform a sieving motion. During operation, the shaking plate performs a variable accelerated motion, materials falling on the shaking plate are evenly delivered to a throwing rod and cleaning sieves under the action of an inertial force of the shaking plate, and the throwing rod is enabled by a crank-connecting rod mechanism to perform a throwing motion in an up- and-down reciprocating manner, which helps to scatter the materials and keep the materials in a wind field for a longer time, giving full play to the cleaning capacity of the wind field. This paper simulates the cleaning device by EDEM-Fluent coupling. The simulation results show that the cleaning device meets the general technical requirements.
