“…Based on the previous research [8,9], it was assumed in this study that the friction force between V-belt and clutch pulley has a negligible effect on the applied stress for durability analysis. The stress analysis for the clutch pulley was investigated to the critical region for the applied load.…”

For the reliability of automotive components, it has to satisfy the dimension accuracy and the strength design requirements for part that has the consistent strength distribution. Since it has the defect due to actual manufacturing process and inhomogeneity of material, the strength design requirement should be not satisfied. In this way, verification of analysis and prediction of fatigue life was very difficult from difference of the failure region. The cold forging products generally has heterogeneity of strength, hardening and fatigue resistance. Therefore, it's important to understand the characteristics of material strength and fatigue of cold forging products considering heterogeneous effect in order to do durability analysis. In this study, in order to propose the method of durability analysis with inhomogeneity of the material, the heterogeneous characteristics are confirmed by predicting the effective strain to perform the plastic deformation simulation influenced from the strength condition and microstructure of pulley at power transmission. Analysis and prediction of effective strain from cold forging is performed by software DEFROM for inhomogeneous characteristics. And the stress of the real operation in performed by MSC.NASTRAN. Also, through correlation about effective strain and hardness, the failure position and the life were estimated to predict the fatigue strength and the external applied stress.

“…The application of Taguchi method has attracted more attention in the literature for the past 20 years and nowadays the Taguchi method has been widely applied to various fields, such as manufacturing system [28], mechanical component design [29], and process optimization [30,31]. The popularity of Taguchi method is due to its practicality in designing high quality systems that provide much-reduced variance for experiments with an optimum setting of process control parameters.…”

Determining the optimal processing parameter is routinely performed in the plastic injection moulding industry as it has a direct and dramatic influence on product quality and costs. In this volatile and fiercely competitive market, traditional trial-and-error is no longer sufficient to meet the challenges of globalization. This paper aims to review the research of the practical use of Taguchi method in the optimization of processing parameters for injection moulding. Taguchi method has been employed with great success in experimental designs for problems with multiple parameters due to its practicality and robustness. However, it is realized that there is no single technique that appears to be superior in solving different kinds of problem. Improvements are to be expected by integrating the practical use of the Taguchi method into other optimization approaches to enhance the efficiency of the optimization process. The review will shed light on the standalone Taguchi method and integration of Taguchi method with various approaches including numerical simulation, grey relational analysis (GRA), principal component analysis (PCA), artificial neural network (ANN), and genetic algorithm (GA). All the features, advantages, and connection of the Taguchi-based optimization approaches are discussed.

“…They reported that increased stiffness is a parameter that indicates ability to withstand durability tests without fail [6]. Shim § This paper is an extended and enhanced version of the technical paper publication (IMECE2015-52008) presented at ASME International Mechanical Engineering Congress and Exposition, Houston, TX, 13-19 Nov., 2015. and Kim (2009) performed shape optimization to get optimal design to increase the fatigue life of the pulley while minimizing the weight of it [7]. Talemi et al (2015) investigated the fretting fatigue behavior of shock absorber washer-disc contact configuration.…”

This paper presents a methodology for re-designing a failed tractor transmission component subjected to cyclic loading. Unlike other vehicles, tractors cope with tough working conditions. Thus, it is necessary to re-design components by using modern optimization techniques. To extend their service life, we present a design methodology for a failed tractor clutch power take-off finger. The finger was completely re-designed using topology and shape optimization approach. Stress-life based fatigue analyses were performed. Shape optimization and response surface methodology were conducted to obtain optimum dimensions of the finger. Two design parameters were selected for the design of experiment method and 15 cases were analyzed. By using design of the experiment method, three responses were obtained: Maximum stresses, mass, and displacement depending on the selected the design parameters. After solving the optimization problem, we achieved a maximum stress and mass reduction of 14% and 6%, respectively. The stiffness was improved up to 31.6% compared to the initial design.
