Optimal Process Conditions for the Manufacture of Aluminum Alloy Bicycle Pedals

Abstract

Numerous forms and manufacturing methods of bicycle pedals exist in current markets. The purpose of this study was primarily to design an innovative forging die for a bicycle pedal company through a simulative analysis, using commercial finite element package software. A series of simulation analyses adopted workpiece temperature, mold temperature, forging speed, friction factor, and size of the mold as variables to evaluate the methods of lightweight in the bicycle pedal forging press. The study involved modifying professional bicycle pedal sizes. The effective strain, effective stress, and die radius load distribution of the pedals were analyzed under various forging conditions. Aluminum (A6061 and A7075) was used to analyze the simulative data. The optimal control parameters were subsequently obtained using the Taguchi methods and a genetic algorithm. The results of the simulation analyses indicated that the design of an experimental forging die can lower the deformation behavior of a bicycle pedal.

Finite element analysis of chip breaker geometry in turning process

“…In this study, by referencing the DEFORMä-3D User's Manual, 13,14 details of the current modeling capabilities that are available in DEFORM TM -3D system can simulate the three-dimensional (3D) metal cutting environment in turning process without any assumptions that are associated with orthogonal cutting conditions. These modeling procedures enable the engineer to study the process response for any changes in process conditions.…”

Study of piezoelectric materials combined with electromagnetic design for bicycle harvesting system

“…17 We selected the above four factors which each has three levels of the piezoelectric materials, as shown in Table 3, and implemented the Taguchi OA L 9 (3 4 ) to perform the experiment, as denoted in Table 4. The parameters of the piezoelectric material included vibration frequency (kHz): 1.3, 4.0, and 6.6; resonant impedance (O): 100, 600, and 400; capacitance value (PF): 47,000, 20,000, and 14,000; and material thickness (mm): 0.2, 0.28, and 0.23.…”

“…where n A is the number of appearances of Factor A in the OA table and (S/N) Am is the S/N ratio of Factor A at level m. This study also analyzed the resonance frequency, impedance, capacitance, and thickness of the piezoelectric materials by applying the Taguchi method. 17 We selected the above four factors which each has three levels of the piezoelectric materials, as shown in Table 3, and implemented the Taguchi OA L 9 (3 4 ) to perform the experiment, as denoted in Table 4.
