Abstract

In making this test equipment, the structural aspect is very important because this test equipment will operate in a wind tunnel and be exposed to quite large wind flow loads, so it is necessary to study whether the structural strength of this test equipment is strong enough to withstand the load or not. The aim of this research is to determine the structural strength of the engine mounting on the test bench test equipment up to the margin of seaft. By using the finite element method. In the process, the dynamic thrust structural test tool uses ANSYS R21 software. To obtain the structure of the dynamic thrust test equipment up to the margin of safety limit, the applied load starts from 10N based on previous research up to 40N. The results obtained at 10N loading were a von Mises of 17.62 and a margin of safety value of 2.68. Where the margin of safety value is said to be safe. At a load of 40N, a von Mises result of 70.9 was obtained with a margin of safety result of -0.07, where this margin of safety value was declared unsafe for use in dynamic thrust test equipment.
