ANALYSYS DESIGN AND FINITE ELEMENT ANALYSIS FOOTSTEP FOR ATTACHMENT ELECTRIC BIKE

Abstract

The 3D modeling of footstep brackets for electric bicycles will be analyzed using finite elementbased software. This research aims to optimize the initial design of the footstep bracket components through the topology optimization method. Topology optimization produced three designs topology design 1, 2, and topology design 3 by varying the holes in the footstep. The static force load chosen was 30 kg. Ductile iron and AISI 4340 materials are used in the footstep bracket. The simulation results show a 23% mass reduction from the initial design, with designs 1, 2, and 3 having respective masses of 0.21, 0.16, and 0.16 kg. For ductile iron material the maximum stress values for designs 1, 2, and 3 are 459.03 MPa, 684.09 MPa, and 643.50 MPa. The FOS values for designs 1, 2, and 3 were 1.2, 0.81, and 0.86. For AISI 4340 material, the maximum stress value from the initial design is 644.60 MPa, topology optimization design 2 686.20 MPa, topology optimization design 3 is 644.06 MPa. The factor of safety (FOS) value for the initial design was 1.1, topology optimization
design 2 value 1, and topology optimization design 3 1.1.
