DESAIN DAN ANALISIS FRAME KENDARAAN TAKTIS MENGGUNAKAN TUBULAR FRAME DI PERUSAHAAN PT. DELIMAJAYA

Tactical vehicles play an important role in military and security operations, so a strong and efficient chassis design is crucial. PT. Delimajaya, a company operating in the bodywork sector, seeks to improve the quality and performance of tactical vehicles through frame design innovation using a tubular structure. This research aims to design and analyze the tactical vehicle frame. The methods used include design using Solidworks software and strength and durability analysis through simulation using ANSYS software. In the crash test at a speed of 50 km/h, the vehicle frame showed a maximum stress of 188 GPa at 5.44 x 10-5 seconds with the minimum Safety Factor value obtained being 0.001149, indicating that the frame was unable to withstand the impact of a collision on the front. . These results indicate that the frame requires design improvements to increase its resistance to collisions. And in the static test, the test results show a maximum stress of 40.7 MPa, far below the material yield strength limit of 235 MPa. The safety factor value obtained is 5.6, , the crash test results show that the frame needs to be repaired at the front to increase its resistance to collisions, while the static load test results show that the frame has very good strength and is safe to use under high static load conditions. tested Keywords: Tactical vehicle, Crash test, Durability, Frame
