Analysis of Rigid Body Dynamic Excavator Crane Arm for Safety use in Mining and Infrastructure Industries using Ansys 16.2

Excavators are one of the heavy equipment that is often used in the mining industry and infrastructure that can do work such as lifting the ground, digging and lifting other heavy objects using its bucket of teeth, making a quarry and moving objects into the tub. Excavators are widely utilized in the mining industry and infrastructure. In this research, it contains the design and analysis of the product of the crane arm excavator which has the form of adoption of catterpillar excavator. Test process conducted using software simulation Ansys 16.2 with Rigid Dynamic project, which is a total deformation test that occurs in crane arm excavator. At the time of analysis is given a joint load on four components that relate one rotation and four others move the rotation. In the components that are rotated rotation is given the limit -300, in the Translansi section is given a boundary -70 mm upper, -80 mm lower and-100 mm in the central part of the crane arm excavator model. A maximum deformation of 982.17 mm is generated and the minimum value generated in the test is 0 mm.
