Analysis of working postures in the assembly process of wheel hay rake using anybody modelling system [Ot toplama tirmigi montaj isleminde çalisma duruslarinin anybody modelleme sistemi ile analizi]

Companies need continuous improvement studies in manufacturing processes to improve the product quality and decrease the costs. the most important factor that affects quality and cost of the product is employee. the investigation,analysis and evaluation of working conditions that affect employees play an important role for improvements to be made in the production processes. long-term and repeated working postures during the manufacturing activities may cause various severity of strain on employee's body and musculoskeletal disorders (msds) in time. msds have a negative effect on employee performance and work productivity. working postures can be analysed using observational methods such as rula,reba,niosh and owas. in addition to these,analysis can also be done using software that allows evaluation considering joint reaction forces by examining the human body according to biomechanical principles. in this study,postural disorders observed in assembly process of wheel hay rake in a company that produces agricultural tools were evaluated using computer aided ergonomics (cae) software anybody modelling system (ams) which provides an analysis of the human body according to biomechanical principles. as a result of the evaluation,a new assembly unit design was proposed to remove the postural disorders during the work.
