Optimisation of Product's Hand-Handle Interface Material Parameters for Improved Ergonomics
نویسندگان
چکیده
Most authors have focused on the sizes and the shapes of the product handles, but neglected those interface materials of the handles, which could further improve the ergonomics of the product. Therefore we utilized optimisation method to determine optimal interface material properties of a product for optimal mechanical response of the system using numerical simulations of a fingertip model grasping a product’s handle. Objective function was set to find material parameters in such way that the interface material of the product stays firm during low grasping forces to provide stability of the product in hands and deforms when a critical contact pressure is reached to provide higher contact area. This increases comfort and lowers the contact pressure on the hand and thereby the risk of injury development.

The grass trimming machine is a widely used agricultural machine for cutting grass by the roadside and in other areas in Malaysia. Hand-arm vibration (HAV) syndrome is very common among workers operating power tools and performing similar work for extended periods. Grass trimming involves the use of a motorized cutter spinning at high speed, resulting in high levels of HAV among its operators. ...

The most frequent and expensive cause category of compensable loss is manual material handling (MMH). Casting workers who handle oxygen (O2) cylinders manually are at risk for work-related musculoskeletal disorders (WMSDs). The aim of this study was to assess manual handling of O2 cylinders by casting workers and to implement ergonomic intervention to reduce the risk of musculoskeletal disorder...
