Simulation and analysis for harvesting Dioscorea hispida tubers

This study discussed an analysis and simulation of fixture stand structure that will use for data collection of force required for harvesting the tubers of Dioscorea hispida. The tubers were surrounded by roots which were well gripped to the soil which made harvesting process difficult. Therefore, a new tool fixture equipped with digital force gauge device to gripped stem dioscorea hispida is required. Imada digital force measurement gauges are state-of-the-art, instruments capable of the highly accurate measurements required in quality testing to determine the strength or functionality of a part or product. The information from the experiments is used to model and simulate the tool in Computer Aided Design (CAD) environment. The solid modelling software Solidworks was used for the design, modelling and simulation of the equipment and the finite element analysis to determine the stress affected on various fixture designs

Design, analysis and fabrication of conceptual innovative hand tool

Dioscorea hispida is a poisonous plant normally found in forest where scientific studies have shown that its tuber contains toxic poison and can be consumed after its poison is removed. Traditionally the tubers were placed in flowing river water for several days. In the harvesting aspect, an innovative hand tool were conceptually designed to replace the traditional hoe or “cangkul”. Using IMADA digital force gauge to measure the force required for pulling out the tuber and reverse engineering methods, an innovative hand tool were designed and developed. The results from experiments showed that the force required for harvesting the Dioscorea hispida tuber is found significant with its weight versus regression squared (R2) of 0.86. The information of optimum force required from field experiment is used to model the simulation and practicality in Computer Aided Design (CAD) environment system. The finite element on stress distribution on selected material of hand tool was simulated by uploading the material characteristic on simulation program embedded in Solidworks software. The end result of the simulation is based on visualization of analysis in Solidworks while producing the hand tool for designing and fabrication from material which is lighter and stronger

Simulation and analysis of innovative hand tool harvester

There is a real need to develop a hand tool harvester since harvesting tubers of Dioscorea hispida (ubi gadong) is time tedious and consuming. The tubers were surrounded by roots, which were well gripped to the soil which made harvesting process difficult. Therefore, a new tool equipped with cutting device to cut the roots of D. hispida is required. The information from the experiments is used to model and simulate the tool in Computer Aided Design (CAD) environment. The solid modeling software solidworks was used for the design, modeling and simulation of the equipment and the finite element analysis to determine the stress, force and displacement were also conducted

Finite element analysis for stress distribution of hand tool harvester

This paper introduced the essential development of an innovative hand tool harvester since harvesting the tuber of Dioscorea hispida is tedious and difficult while the existing hand tool is heavy. The information of optimum force required from field experiment is used to model the simulation and practicability in Computer Aided Design (CAD) environment system. Several tests of maximum/minimum stress and displacement on different material of hand tool were simulated by uploading the material characteristic on simulation program embedded in Solidworks software. Three materials which were commonly available in market namely Plain Carbon Steel, Aluminium Alloy and Cast Carbon Steel were chosen. This modeling software is very helpful to manage the model and simulate the workability of the designed equipment through stress and displacement mode analysis. The comparison between the tools that are based on the acquired land and tuber weight factor were also noted via Solidworks simulation. The end result of the simulation is based on visualization of analysis in Solidworks while producing the hand tool for designing and fabrication from lighter and stronger material
