Deskripsi Analisa Kasus

A base stand assembly includes a base, a holder, and a pin, as shown in the following figure. The stand assembly is made of structural steel. Assume a no separation condition for all contact regions. Determine the deformation and von mises stress distributions of the assembly under the given load and boundary conditions

Deskripsi Masalah Numerik Menggunakan panduan Ansys Case Study Three Dimensional Elasticity, Penulis akan menganalisa struktur base, holder, and pin dengan spesifikasi sebagai berikut: • Material = Structural Steel • E = 200 GPa Boundary Condition • •

The bottom face of the leg base are fixed A downward force of 1 kN is applied to the holder’s top face

Geometry Construction • •

The bottom of the hub base is 35 mm above the ground level The holder is 36 mm tall, 18 mm of the which is in contact wit the hub base
