Design and Development of Bamboo Link Mechanism using Synthesize Adhesive at Bamboo Joints

Abstract

Bamboo articles used in the daily life make the market more profitable because of the easier availability with low cost and comfort with the environment without any type of pollution. The bamboo is used as the constructional materials from the initial period in the rural areas and even in the modern society for the decorative appearance mostly used as the mechanical properties of bamboo is concerned compared to the mild steel used in many applications. This makes the development of bamboo articles, constructional and mechanism purpose more beneficial in the rural areas and provided the job opportunities and livelihood in the rural communities. Developed adhesive is prepared with the replacement of bamboo dust and the replacement of 25% phenol formaldehyde. Developed adhesive is applied to the mechanism made from bamboo links instead of applying adhesive available in market to test the performance of developed adhesive in predict the mechanical properties. It is found that developed adhesive is good for structural members of which the mechanism is fabricated in terms of tensile, shear and compressive strength compared to available adhesive considering cost and manufacturing. The paper details the performance of the six-bar chain mechanism made from the bamboo linkages and bamboo joints with the applying appropriate developed bamboo adhesive to the bamboo joints. The experimental setup made from the bamboo links using synthesize adhesive is six bar mechanism which is tested with the varying load 5 to 9.5 Kg to predict a performance for six bar chain mechanism and observed the behavior related to angle of oscillation, weight bearing capacity, link length limitation at constant and varying speeds 12-16 rpm. The experimental observation is recorded and based on this recorded data a mathematical model is developed to correlate a relationship between causes and effect involved in the experimentation, so that effective measures can be taken to control required performance for light duty machines.
