Abstract:
The finite element method was implemented to design and analyze the metal molds used in forming processes of passenger car safety wheels. The objective is to analyze the heat transfer, heat dissipation, heat loss of the metal mold, and safety wheel by using the SolidWorks program to design mold parts and mold assembly. The finite element method was used to develop finite element models for metal molds and 3D safety wheels, particularly the SolidWorks Simulation program. The metal mold of run-flat safety wheels was heated during the extrusion process from a press with an internal heater. Molds were designed to function at temperatures up to 300°C. To create metal molds and conduct heat transfer studies, the SKD11 material, another substance with great mechanical and thermal properties for mold manufacturing was chosen. The mold was designed to place a rustproof metal structure inside the mold to strengthen the Run Flat Safety Wheel and to hold the Run Flat Safety Wheel together. The finite element analysis results showed heat transmission, heat distribution, and heat loss of the mold and safety wheel. The melting of the polymer composite powder or rubber composite occurred as a result of the heat being transferred from the mold to the polymer composite powder or rubber composite contained inside. The rust-proof steel structure would be covered with polymer composite powder or molten rubber composite. The strong, inventive, and resilient safety wheels would be constructed by encasing the rustproof steel frame in polymer composite powder or molten rubber composite. In addition, it was discovered that heat loss from the molds outside had no impact on how heat was distributed inside. Before the workpiece is taken from the mold, it must be cooled to lower its temperature.
