PERANCANGAN DAN ANALISIS TRAILER RACK SEPEDA MOTOR PADA MOBIL DAIHATSU TAFT DENGAN BANTUAN SOFTWARE AUTODESK INVENTOR
Trailer rack is an additional device mounted on a four-wheeled vehicle to transport a motorcycle mounted on the rear of the car frame. In this design, the Daihatsu Taft off-road vehicle that attracted many outdoor sports fans was chosen as the subject of designing the bracket adapter for the trailer rack. The concept development in the trailer rack design comes from the technical specifications obtained through the Quality Function Deployment (QFD), which is a methodology used by designers to anticipate and determine the priorities of consumers 'needs and desires, as well as combining these consumers' needs and desires in products developed with consumer oriented. The design method, along with the stages in the process of designing the rack trailer in addition to using the QFD method, also refers to the guidelines of the German Engineer Association (Verein Deutsche Ingenieuer/VDI) at the analysis stage to obtain the desired technical specifications. Furthermore, the virtual 3D trailer rack model is made with Computer aids Drafting and Design software (CADD). The design and analysis of the design of the trailer rack focuses on the analysis process using ASTM A-36 material on the rack trailer frame with a motorcycle load weighing ≤ 200 kg. In the simulation of loading using Autodesk Inventor software, the values due to load include: Von misses stress of 107.3 MPa, 1st Principal Stress of 111.2 MPa, 3rd principal stress of -114.1 MPa, displacement of 0.13 mm, and a safety factor of 2.31 ul.
