THE STRESS SIMULATION ANALYSIS OF COPPER ALLOY C84400 IN A HELICAL GEAR

The Copper Alloy-Zeng is an alloy of copper and zinc in proportions that can be varied to achieve various mechanical and electrical properties. In a mechanical system, the gears are an important component used to increase or decrease torque, change the direction of motion and transmit power from a motion system. The easy alternative for carrying out calculations and comparing them with real conditions is simulation analysis. The stress analysis uses the finite element method with Solidworks 2021 software to save time and costs. The aim of this research is to analyze Von Misses stress using the finite element method with Solidworks 2021 software on helical gears made from copper alloy type Copper Alloy C84400 to obtain the Von Misses value where the Von Misses value can predict material failure. The result of this research was the Von Misses Stress values in this study are based on different forces, namely 10 N, 20 N, 30 N, 40 N, and 50 N, which have Von Misses Stress values of 0.085 MPa, 0.171 MPa, 0.256 MPa, 0.341 MPa and 0.427 MPa. Because the Von Misses Stress value that occurs is below the yield strength value of 105 MPa, this helical gear only experiences elastic deformation. The results of the analysis of the helical gear at forces of 10 N, 20 N, 30 N, 40 N, and 50 N showed safety factor values of 1230, 615, 410, 308, and 246, indicating that the strength of the material > the stress that occurs. Therefore it can be said that this helical gear is not safe to use.
