Tujuan dari penelitian ini adalah untuk merancang mesin uji universal dan menganalisis kekuatan konstruksi mesin uji universal sebelum di lakukan pengujian, untuk merancang dan menganalisis kekuatan konstruksi menggunakan software solidworks dan fitur simulasi, dimana dalam fitur ini akan di amati proses keluaran untuk hasil von misses stress, strain, displacement dan safety factor. Dalam penelitian ini akan di lakukan variasi pembebanan 100 Kg, 200 Kg dan 300 Kg di titik tempat pengujian rangka konstruksi. Hasil dari penelitian ini didapatkan untuk nilai terbesar pengujian tarik untuk beban maksimal 300 Kg degan nilai von misses stress maximal 109 N/〖mm〗^2, strain maximal 0,00038, displacement maximal 0,077 mm dan safety factor minimum 2,6, kemudian nilai terbesar pengujian bending untuk beban maksimal 300 Kg dengan nilai von misses stress maximal 20 N/〖mm〗^2, strain maximal 0,00038, displacement maximal 0,009 mm dan safety factor minimum 14. Dari hasil pembebanan kedua pengujian hasil von misses stress tidak melebihi yield strenght material sebesar 290 N/〖mm〗^2 kemudian untuk hasil strain dan displacement masih bersifat elastis dan hasil safety factor aman. Setelah itu hasil dari perbandingan perhitungan manual dengan hasil solidworks didapatkan persentase galat terbesar untuk perhitungan displacement dengan selisih error 44% dan persentase galat terkecil pada perhitungan safety factor dengan selisih error 0%.

The purpose of this study was to design a universal testing machine and analyze the construction strength of the universal testing machine before testing, to design and analyze the construction strength using solid works software and simulation features, where in this feature was observed the output process for the results of von misses stress, strain, displacement and safety factor. In this study, variations of loading of 100 Kg, 200 Kg and 300 Kg were carried out at the point where the construction frame was tested. The result of this study were obtained for the largest value of tensile testing for a maximum load of 300 Kg with a maximum von misses stress value of 109 N/〖mm〗^2, a maximum strain of 0.00038, a maximum displacement of 0.077 mm and a minimum safety factor of 2.6, then the largest value of bending testing for a maximum load of 300 Kg with a maximum von misses stress value of 20 N/〖mm〗^2, maximum strain of 0.00038, maximum displacement 0.009 mm and minimum safety factor 14. From the results of the second loading test, the results of von misses stress did not exceed the yield of strength material of 290 N/〖mm〗^2, then for the results of strains and displacement were still elastic and the safety factor results were safe. After that, the results of comparing manual calculations with solid works results obtained the largest percentage of errors for displacement calculations with a difference of 44% errors and the smallest percentage of errors in safety factor caculation with an error difference was 0%.
