Simulation technology enables product and process designers to evaluate designs in increasingly realistic and complex settings. Computer simulation has been around in many forms for over 30 years, although only with the invention of the workstation has simulation become widely accepted by so many diiferent users. Most engineers have had some exposure to(More)
To study the physiological and psychophysical costs of symmetric and asymmetric manual materials handling, two tasks were performed by 30 industrial subjects. In both tasks, box weight and handle position were varied. The symmetric task, lifting and lowering between floor and conveyor, showed handles to be beneficial. The asymmetric task was palletizing and(More)
Computer simulation is becoming a common tool in the engineer's toolkit but the move to simulation is slow in coming. There are still many people in manufacturing, health care, process reengineering and human factors industries who are not using any sort of simulation software and see no advantage to using this powerful tool. Even in the information age of(More)
Earlier studies of the biomechanics of handle placement and angles on boxes in Manual Materials Handling have been limited to sagittally symmetric tasks. This study extends the results to a palletization/depalletization task with considerable asymmetric movement. Part 2 shows how body posture, hand/handle interface, and disc compressive force change in this(More)
