Lightweight Design of Tractor Drive Axle Housing based on Six Sigma Robust Multi-objective Optimization

Paper ID- AMA-23-11-2021-10869

According to the consideration of safe use, the design of tractor driving axle housing is too conservative, with its strength failing to demonstrate. Aiming at the lightweight design of the axle housing, this paper proposes a design method to ensure the reliability and robustness of the axle housing on the basis of realizing the lightweight. Firstly, based on the analysis of the natural frequency of the axle housing, the finite element model is verified, and the resonance phenomenon is analyzed. Secondly, the optimal area of axle housing is determined by the results of variable density topology optimization and the fatigue accumulation damage theory. In the optimized area, the shell thickness variables are selected by sensitivity analysis. Thirdly, based on the radial basis function (RBF) approximate model, a six-sigma robust optimization algorithm is adopted to optimize the axle housing with mass, equivalent stress, displacement and safety factor as the objective function. The simulation results show that the design variables, strength, stiffness and safety factor of the optimized drive axle housing reach 8σ level, and the mass of the axle housing decreases by 9.7%. Moreover, compared with the deterministic optimization design based on genetic algorithm, the safety factor, strength and stiffness of the bridge housing through the proposed method can be improved relatively while achieving the goal of lightweight, and meanwhile it provides a technical reference for the structural lightweight design of vehicles and other machineries.

Performance Improvement of Fruit Battery-based Sensor with Charging Technique

Paper ID- AMA-22-11-2021-10868

The grades of oil palm fresh fruit bunches (FFB) influences both processing and market values as this oil palm sector is highly contributed to Malaysia’s Gross Domestic Product (GDP). Traditional techniques used during the screening process must be enhanced in order to minimize the quantity of low-quality oil palm that is delivered to the mills for further processing. This study presents an innovative method to grading the oil palm, based on a fruit-based maturity sensor with charging technique. The sensor's sensitivity is evaluated by examining the relationship between the sensor voltage and the moisture content of the oil palm fruit, which is done with the use of several set of electrodes in this research. When a four-set of electrodes in fruit battery was utilized instead of a single set of electrodes, the sensitivity of the sensor improved by triple times for the range of 50 to 80 per cent moisture content, compared to the single-set of electrodes. The accuracy of fruit maturity grade is the common difficulty encountered throughout the receiving process, was substantially enhanced as a result of the suggested method.

Study on The Mechanical and Control Aspect in the Design of a Robotic Harvesting System for Vertical Farm

Paper ID- AMA-22-11-2021-10867

According to The United Nation (UN), 80% of the world population are predicted to be living in the Urban area by 2050, food security is going to be a real issue especially in the urban area. Therefore, sustainable agricultural solutions like vertical farming, indoor farming and robotic harvester are to be widely studied and explored in order to ensure the survivability of humankind of the next generation are secure. This paper presents some of the critical parameters needed to design a robotic harvester in a vertical farming greenhouse. The vertical farm in this study has 5 levels with 3 rows on each level and adopting the Nutrient Film Technique (NFT) Hydroponic system. The robotic harvester was proposed to have a robotic arm moving on a vertical and horizontal rail. The robotic control system was design to work wirelessly using Radio Frequency (RF) as the transmitter. Five experiments were done in order to determine some of the critical parameters and the parameters were wireless connectivity, wireless coverage, robot aim calibration, robot arm torque limitation and natural arm movement programming approach.

Soil Compaction Effects of Large and Mini Combine Harvesters in a Paddy Cultivation Area in MADA

Paper ID- AMA-22-11-2021-10866

The most effective mechanization technique for harvesting yield in rice field cultivation is the use of a combine harvester. A variety of combine harvesters are used in the Muda Agricultural Development Authority (MADA) region, with the majority of them being locally modified large combine harvesters (CB). Concerns about soil compaction (SC) persuade the local government to provide a mini combine harvester (CM) as an alternative machinery. However, the extent of soil damage caused by the varying weight and contact pressure of combine harvesters has not been clearly reported. As a result, the goal of this study was to compare the SC effect of two types of combine harvesters used in the MADA region: CB and CM. The test plots were chosen from a total of 2.6 ha in Tunjang, Wilayah II – Jitra, Kedah, and were planted in silty clay soil texture during both wet and dry seasons. Over 10,000 data points on SC were collected using a soil penetrologger. Normalized SC values shows better approach in identification of drastic change of SC at specific soil depth. The SC also shows no significant different on straight vs. cornering both for CB and CM. At a critical soil depth of >30 cm, it was discovered that the compaction caused by the CB was 7 to 10% greater than that caused by the CM. However, there was no noticeable difference in SC effect at the top soil layer (0-30 cm) from different type of combine harvester. Thus, the long-term impact of CB deployment must be considered due to changes in farming techniques and climate variability, such as soil water content during the monsoon season.

Influences of Dressing Parameters on Wheel Wear in Internal Cylindrical Grinding Operation

Paper ID- AMA-22-11-2021-10865

An important factor in the internal cylindrical grinding process (ICGP) is grinding wheel wear (Gw). One of the important factors affecting the Gw value is the dressing parameters. Thus, this work inspected the impact of dressing parameters on the Gw value in the ICGP using the Taguchi method. The implemented experiments considered the L16(44x22) orthogonal array on an internal cylindrical grinding machine. The selected process parameters are dressing feed rate (S), rough dressing times (nr), fine dressing times (nf), rough dressing depth (ar), fine dressing depth (af), and non-feeding dressing (nnon). Based on the Taguchi method, the impact of these input on the Gw value in the ICGP was calculated. The impact level of nr on Gw value is the biggest (equivalent to its influence level is 55.08%). Then, another important influencing factor for Gw was found to be nnon with 17.78%. The smallest influencing factor on Gw is S. In addition, the optimal dressing parameters has been determined. The optimal dressing mode for the minimize Gw value includes one times the rough dressing with a cutting depth of 0.025 mm/stroke, two times the fine dressing with a cutting depth of 0.015 mm/stroke, two times the non-feeding dressing and a feed rate of 1.2 m/min.
