Elastic Linear Analysis of Connecting Rods for Single Cylinder Four Stroke Petrol Engines Using Finite Element Method

A connecting rod is one of the most critical parts in engine assembly which transfers energy from the piston to the crankshaft. The connecting rod mainly undergoes tensile and compressive loading under engine cyclic process. The forces acting on the connecting rod are forces due to maximum combustion pressure and forces due to the inertia of the connecting rod. This research aimed to analyze the design of the connecting rod of single-cylinder four-stroke engines. This study used CAD software for modeling and structural design. Stresses generated across all the locations of the connecting rod were evaluated using FEA Software. Elastic linear analysis of model design was also performed. The simulation results in this study have led to the conclusion that failure occurred due to the incorrect selection of materials. Among all materials under study, AA 6061 is considered the most suitable material for use at high RPM. In fact, aluminum is preferable for use at high RPM

ABSTRAK   Lubis, Didin Zakariya. 2013. Effect of Occupational Health and Safety for The Satisfaction and Healthness of Machines Production Workshop Workers at District Tulungagung. Minithesis. Mechanical Engineering Department, Faculty of Engineering, State University of Malang. Supervisors: (1) Drs. Solichin, S.T, M.Kes., (2) Drs., H. Suwarno, M.Pd.   Keywords: safety for work, healthness for work, satisfaction and healthness forwork Machine production workshop was a place to perform maintenance, repair and modification of machines, where the manufacture and assembly of machine parts take place. Basically, about (85%) accidents occurred by negligence and human error factors. The company or industry may has a qualified safe conditions for example by providing Personal Protective Equipment (PPE), but the workers did not often want to wear PPE. The reason was, they could not work and move freely. Based on that, it should be an understanding of Occupational Health and Safety (K3) and K3 facilities to improve and implemented the use of personal protective equipment on an ongoing basis. The main objective of this study was to determine the employees understanding of the Occupational Health and Safety (K3), K3 facilities at the workshop as well as the influence of occupational health and safety for the satisfaction and healthness of machines production workshop workers at district Tulungagung either partially or simultaneously in groups experimentation and control. This research includes quasi-experimental study. Subject of research in the form of four workshops experimental group and the four workshops control group. The respondents need to complete questionnaires taken from each workshop on 5 workers. Data collection method was used questionnaires, check lists and documentation, while the data analysis applied in this study was a prerequisite test analysis, descriptive analysis, multiple regression, and hypothesis testing using SPSS 17 for Windows. The results showed that about 70% workers understand the Occupational Health and Safety (K3) under “enough” category, K3 facilities in workshop machine was decrease approximately 62.5%, while differences in the experimental group comparisons significantly greater than the control group. It was characterized by the t-test results for the experimental group which had a significance level of 0.05 (0.309) on the variable of personal protective equipment. F-test values for each group have significance level of < 0.05 (0.0

Design and development of a CNC micro blanking machine with mechanical and control validation investigation

The increasing of needs on several industrial fields such as medical, electrical and mechanical field require accurate dimensional and geometrical function and efficiency in a product, one example being the manufacture of micro-hole and micropart products. As one of micromachining processes, CNC micro blanking machine is proposed as basic technology to fabricate the component with miniaturized dimension. In this study, the validation between theoretical input on the program control and mechanical motion is conducted to significantly reduce the gap between actual carriage motion and G-Code motion. The average deviation of actual velocity on post calibration is determined to be 10.8 mm/min, while for carriage displacement for X, Y, and Z axes are -0.0191; -0,0087; and -0.0005 mm, respectively. Based on the analysis has been performed, it can be concluded that the imprecision is caused by the geometrical deviation of carriage (linear guide), so, the carriage movement is hindered by the deviation

The Effect of Thickness and Type of Material on the Sheared Edge Characteristics of Keychain Cranioplasty Plate Blanking Product Using Eccentric Press Machine

Keychain cranioplasty plate product has the potential to be produced using the blanking process because it is faster, low-cost, and requires low-energy consumption compared to other mechanical operations. This research aimed to find the effect of material thickness and type on the sheared edge characteristics of keychain cranioplasty plate using the blanking process to meet the international health standard. Experimental research conducted using an eccentric press machine with 40 tons capacity. This research’s test material parameters of titanium (Ti-6AL-4V) and stainless steel (SS-316L) were the 0.5 mm, 0.6 mm, and 0.8 mm thickness with a maximum blanking velocity of 3000 mm/min and 2.5% punch-die clearance. Then, the blanking products were observed using a digital microscope. The results showed that the optimum blanking product quality was found in the titanium (Ti-6AL-4V) and stainless steel (SS-316L) materials with 0.6 mm thickness because it had stable sheared edge characteristics in each zone compared to other variations

Elastic linear analysis of CNC micro blanking machine using finite element method

This study has developed Micro Punch CNC Machine design by optimizing the function of the actuator axis implemented to make an implant plate. This research aimed to plan the simulation of CNC machine construction strength using the blanking operation application. Finite element method (FEM) was used to analyze the material strength. The research results showed that the maximum stress occurring at the punch tools was 428.17 MPa with the thickness of 0.6 mm and the maximum thickness of workpiece allowed in making the implant plate was 1.4 mm with the maximum stress of 999.09 MPa. The obtained data indicate that the most effective material to be used as the material construction in CNC micro blanking machine is St42. This case is proven by the result of the power to resist the stress and the value of maximum deformation from the comparison of both materials
