Human Modeling And Simulation

More and more, digital human modeling and simulation is being used in conjunction with CAD systems to address ergonomic issues early within the development and manufacturing process. However, purchasing a human modeling software package does not guarantee a user-centered design anymore than purchasing a word processor makes someone an author. This paper addresses some of the practical issues that confront human modeling and simulation users, including the collection of geometry, posturing the manikin, and selection of an analysis. For the purposes of discussion, human simulation will be divided into three broad areas: the environment, manikin selection, and analysis.

Human Modeling And Simulation

A work tool that don’t have ergonomic aspects can cause excessive fatigue to injury when used. As a result of excessive fatigue on workers can reduce the level of productivity and harm the company. PT. X is a manufacturing companies with make to order type of production. PT. X received a complaint from a customer who suffered a musculoskeletal muscle injury while using a checking fixture work tool. Checking fixture is a supporting component in the process of making a product that has a great influence on the quality of the product that will be optimized for its function and geometry. The study was conducted to find a checking fixture design that suits the customer's wishes. Ergonomic aspect analysis will be carried out to determine the dimensions of the dimensions in the process of making the design of the checking fixture by considering several things including the distance of the hand's reach to the locator pin, the height of the checking fixture, the standing position and the position of the grip checking fixture. Ergonomics analysis will be conducted using digital human modeling and simulation software. The design for manufacturing and assembly method is used to determine the costs required to make a checking fixture. Based on the analysis of the design, the proposal shows that there is an improvement in the work posture, which is indicated by a decrease in the PEI value from 2.73 to 1.82 so that the number of production has increased to 93 units. Based on the analysis of design for manufacturing and assembly the cost of making the checking fixture is Rp. 5,145,115,000/item. Keywords : Antropometri; Nordic Body Map; Posture Evaluation Index.ABSTRAKSebuah alat kerja yang tidak memenuhi aspek ergonomis dapat menyebabkan letih berlebih hingga cidera ketika digunakan. Akibat dari letih berlebih pada pekerja dapat menurunkan tingkat produktivitas dan merugikan perusahaan. PT. X adalah perusahaaan manufaktur dengan tipe produksi make to order. PT. X mendapat keluhan dari pelanggan yang mengalami cidera otot muskuloskeletal ketika menggunakan alat kerja checking fixture. Checking fixture merupakan satu komponen pendukung dalam proses pembuatan produk yang sangat berpengaruh besar terhadap kualitas produk yang akan dioptimalkan fungsi maupun geometrinya. Penelitian dilakukan untuk menemukan desain checking fixture yang sesuai dengan keinginan pelanggan. Analisis aspek ergonomis akan dilakukan untuk menentukan standar dimensi dalam proses pembuatan desain checking fixture dengan mempertimbangkan beberapa hal diantaranya jarak jangkauan tangan ke locator pin, tinggi checking fixture, posisi berdiri dan posisi genggaman checking fixture. Analisis ergonomi akan dilakukan menggunakan software digital human modeling and simulation. Metode design for manufacturing and assembly digunakan untuk mengetahui biaya yang diperlukan untuk membuat checking fixture. Berdasarkan analisis desain usulan menunjukkan bahwa terjadi perbaikan postur kerja yang ditunjukkan dengan menurunnya nilai PEI dari 2,73 menjadi 1,82 sehingga jumlah produksi mengalami peningkatan menjadi 93 unit. Berdasarkan analisis design for manufacturing and assembly biaya pembuatan checking fixture adalah Rp. 5.145.115.000 per unit. A work tool that don’t have ergonomic aspects can cause excessive fatigue to injury when used.

Computational human factors tools are often not fully-integrated during the early phases of product design. Often, conventional ergonomic practices require physical prototypes and human subjects which are costly in terms of finances and time. Ergonomics evaluations executed on physical prototypes has the limitations of increasing the overall rework as more iterations are required to incorporate design changes related to human factors that are found later in the design stage, which affects the overall cost of product development. This paper proposes a design methodology based on Digital Human Modeling (DHM) approach to inform designers about the ergonomics adequacies of products during early stages of design process. This proactive ergonomics approach has the potential to allow designers to identify significant design variables that affect the human performance before full-scale prototypes are built. The design method utilizes a surrogate model that represents human product interaction. Optimizing the surrogate model provides design concepts to optimize human performance. The efficacy of the proposed design method is demonstrated by a cockpit design study.
