Abstract
The conceptual design, solid modeling, computer aided static analysis of frames and plates of a continuous process breadfruit (Treculia africana Decne) de-pulping machine is presented. The aim is to improve the method of breadfruit de-pulping in rural areas by creating a mechanism that de-pulps the seeds and to carry out a static analysis on the frame and plates. The conceptual design was gotten from mechanization of the traditional method of de-pulping and also from exiting literatures. The modeling was done using computer aided design software. The machine has an overall dimension of 2522mm × 540mm × 1198mm as its length, width and height respectively and weighs approximately 178kg as modeled. Static analysis/ Finite Element Analysis (FEA) were carried out on the frame and the plates of the machine using computer aided design simulation software. This is to ascertain the level of deformation and strength check on the plates and frame. The specific material of the component, load, torque and constraints were specified on the simulation environment before simulation. The material assigned to the frame and plates are mild steel. Von Mises failure criterion was used to examine the effects of the forces and torque on the plates and frames. The result showed that the stresses and the displacement are within the acceptable limit for the design. The results of finite element analysis (static analysis) and the deformation analysis on the frame and plates show von misses stress value ranging from 0.042-52.33 Mpa for the plates and 16.47 Mpa for the frame. The maximum deformation on the frame is 0.164 mm. It is recommend that frame and plates should be fabricated likewise the mechanical functional design, fabrication and testing of the machine. it will also eradicate the tedious nature involved in the traditional way of de-pulping and cleaning of the breadfruit seed.
