After being cooled by using several cooling media, it was continued with impact and microstructure testing. The results showed that AISI 1020 steel specimens using air cooling media, had the average impact strength value of 19.1 joules/mm, while those using oil cooling media had an average impact strength of 35.2 joules/mm, and those using grease cooling media had an impact strength of 45 joules/mm. From this data, the one with the highest impact strength value was the grease cooling media at 45 joules/mm and the one with the lowest impact strength was the air cooling media, namely 19.1 joules/mm. The results of metallographic observations were obtained when the grease media was used, the distribution of ferrite was reduced and did not have time to form, whereas in steel that was cooled with oil, the distribution of ferrite was almost the same as the untreated material and for air media, the shape of the ferrite structure spread and formed evenly.","PeriodicalId":513368,"journal":{"name":"Jurnal Permadi : Perancangan, Manufaktur, Material dan Energi","volume":"496 4","pages":""},"PeriodicalIF":0.0,"publicationDate":"2024-01-31","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"140480065","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

The main of this research is to see response of harmonic oscillatory sinusoidal with amplitude 0.02 m and frequency of 0.5 Hz, response of the damping force and spring force of a hydraulicpneumatic suspension using ideal PID controller. Simulation using MATLAB and Simulink to see continuous results with a time of 20 seconds. The test was carried out on the rear wheels with quarter vehicle systeml, by replacing the conventional suspension with a hydraulicpneumatic which has an orifice diameter of 2 mm and a piston of 78 mm using ASTM D 1298 oil of , for the gas accumulator it has the initial pressure and volume in both cylinders is , of with a floating piston diameter of 78 mm, produces harmonic oscillation movements of the vehicle that are smaller than the road profile conditions, and experience a stable condition at 6.2 seconds. And the maximum oscillating force produced by the mattrack is almost the same as the road profile conditions which produce good road holding.","PeriodicalId":513368,"journal":{"name":"Jurnal Permadi : Perancangan, Manufaktur, Material dan Energi","volume":"23 ","pages":""},"PeriodicalIF":0.0,"publicationDate":"2024-01-31","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"140474819","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
