Abstract

Waist assistive power suit will be develop to prevent lower back pain for workers in industry. The significant of this research are this product can use by industry worker especially for carries heavy load and also can be used by the patient with a problem to do task normally. The exoskeleton spine are design to follow the 3 different types of DOF such as spine flexion(forward bending), spine lateral flexion(sideways bending, left or right) and spine rotation( rotation around the vertical axis). Each movement has each angle stress limitation on human body, thus the design are created to ensure that the waist assistive suit can protect the posture of human body while help to increase productivity by created a suit that give enough force to do their work productively. The objective of the project is to design and develop waist assistive suit while able to validate the design of waist assistive suit. Waist assistive power suit will use concept of human spine which can move in three degree of freedom (flexion, lateral flexion, and rotation). Hence the design will be concentrate into making a waist assistive suit that are reliable and mathematically proven in weight ratio in required torque to lift a load. The design will start by draw a model by using Solidworks software and the model will be simulate using a simulation in Solidwork software. Then the prototype will be fabricate and the analysis on the mechanism will be take place regarding weight, stress, strain, assistive torque using the spring, motor and material selection. From the result, we know that the maximum yield strength for alloy steel is 54 kg if applied direct force to material. The assistive torque that the spring correspond to the 7 kg load is 2.94 Nm. From the graph it shows that the increase of load and distance will increase the assistive torque produced by spring
