Abstract

People with physical movement disabilities will likely to have some difficulties in moving from one place to another. A wheelchair has been invented for them in order to make their daily life become easier. Although the use of wheelchair can help people with disabilities to move, they still have a problem in getting onto the bus. Therefore, a few mechanisms such as hydraulic wheelchair lift, ramp and bridge plate has been invented to solve this problem. The purpose of this project is to introduce a new mechanism and improve the existing wheelchair mechanism to help wheelchair users to get into the bus. This new mechanism was designed to enable a lifting process occur at the standard bus that has a high stairs. The design process of this mechanism is started with a survey among civilians which includes some person with disabilities and some students. Through the data obtained from the survey, a House of Quality has been produced to convert the customer requirements into the engineering characteristics. Then, a Product Design Specification is produced in order to be used as a project target specification that must be met. Furthermore, a Morphological Chart is used to obtain some conceptual design whereas the final designs is selected through the Weighted Decision Matrix. After the 3D final design is produced using SolidWorks 2016, some analyses and simulation has been carried out in order to obtain the workability and functionality of the design. A motion study was conducted to observe whether the product design is able to lift the required load or not. Using motion study, the trace path, velocity, acceleration and amount of force use to lift the required load can be determined. Next, a simulation on stress analysis is conducted to obtain the stress data so that the factor of safety of the product design can be classified. Conclusion and recommendation about the project are discussed further
