This study aimed to determine the optimum washing of laboratory washing model that design to stimulate the active washing process and passive commercial washing machine are compared in order to determine the best washing result. Variables of the study include water speed, washing time and radial nozzle inclination angle. The rotational system of an automatic washing machine has two major technical difficulties. One is the collision of the tub against the frame at the beginning of its early spinning stage. A factor that causes such instability of the rotational object can be attributed to the deflection of the liquid inside the liquid balancer due to the unbalance mass. Proposed a new washing technology and new design of the washing machine can be as a base of its new type. These machines have better outcome data; improve quality of washing process and effective use of washing liquid. New washing machine is simple design, does not have rotary parts at all and uses active process of washing process with squeezing of linens and more productive then known washing machines. Also, this machine can recycle and feed cleaned washing liquid. Additionally, in use of ultrasonic technology of washing process, new machine today will be perfect design.

Design and analysis of solar car chassis

2020 , Radhwan Hussin , Shayfull Zamree Abd. Rahim , Mohd. Nasir Mat Saad , Abdellah el-hadj Abdellah , Irfan Abd Rahim

A solar car is a lightweight, low power vehicle designed and built with a single purpose in mind–racing with and only drive during the day. It has limited seating (one or two peoples) and usually has very little cargo capacity. However, it offers an excellent opportunity to develop future technologies that can be applied to practical applications. This study will focus on design and analysis solar car chassis part. The primary challenge in developing an effective solar car chassis is to maximize strength and safety while minimizing the weight. Every extra pound requires more energy to move down the road. However, safety is a primary concern and the chassis must meet stringent strength and safety requirements. The purpose of the study is to understand the concept design of solar car chassis in terms of calculation, material selection, chassis style selection and virtual analysis for chassis using CATIA software.

Achieving good quality of products from plastic injection moulding processes is very challenging, since the process comprises many affecting parameters. Common defects such as warpage are hard to avoid, and the defective parts will eventually go to waste, leading to unnecessary costs to the manufacturer. The use of recycled material from postindustrial waste has been studied by a few researchers. However, the application of an optimisation method by which to optimise processing parameters to mould parts using recycled materials remains lacking. In this study, Response Surface Methodology (RSM) and Particle Swarm Optimisation (PSO) methods were conducted on thick plate parts moulded using virgin and recycled low-density polyethylene (LDPE) materials (100:0, 70:30, 60:40 and 50:50; virgin to recycle material ratios) to find the optimal input parameters for each of the material ratios. Shrinkage in the x and y directions increased in correlation with the recycled ratio, compared to virgin material. Meanwhile, the tensile strength of the thick plate part continued to decrease when the recycled ratio increased. R30 (70:30) had the optimum shrinkage in the x direction with respect to R0 (100:0) material where the shrinkage increased by 24.49% (RSM) and 33.20% (PSO). On the other hand, the shrinkage in the y direction for R30 material increased by 4.48% (RSM) and decreased by 2.67% (PSO), while the tensile strength of R30 (70:30) material decreased by 0.51% (RSM) and 2.68% (PSO) as compared to R0 (100:0) material. Validation tests indicated that the optimal setting of processing parameter suggested by PSO and RSM for R0 (100:0), R30 (70:30), R40 (60:40) and R50 (50:50) was less than 10%.

Design and analysis of Garlic Peeler machine

2020 , K Y Yen , Radhwan Hussin , Shayfull Zamree Abd. Rahim , Mohd. Nasir Mat Saad , Abdellah el-hadj Abdellah

The purpose of this research is to design and analysis of a Garlic Peeling Machine. The traditional hand peeling garlic method is very tedious and time-consuming work once a bulk quantity of garlic to be peeled, especially for restaurants. The pungent smell of garlic will make the uncomfortable for user’s hands and eyes. Hence, the goals to be achieved in this research are to design a garlic peeling machine to replace the manual working in order to reduce the time taken compared to the hand peeling method. The research scopes involved of design and generate idea concepts, simulation and analysis structure and undergo experiment. The process flow of this research begins according to the standard design process flow. A survey was conducted to collect the customer’s requirements. After idea generation, the final concept was selected using Pugh method and Weighted method. Simulation of fluid flow was carried out using computational fluid Dynamic (CFD) software.
