Design and Fabrication of Retractor Durability Test Prototype

摘要

In India, it is mandatory to test a safety belt for its durability according to prescribed standard before it is tested under dynamic conditions. This is done with regard to passenger safety in the event of an accident. The durability of the belt is evaluated for about 45,000 cycles under prescribed load. Present day demand for testing of belts has increased tremendously due to the growth of the Indian automotive sector. To cope-up with this ever-increasing demand, a need has arisen to design a new machine altogether which would be capable of testing seat belts and which would operate on the latest principle of servo-motor technology. This machine would also be a compact one and will be nearly of the same dimensions as the existing one, considering the space constraints. Aim of this paper is to design and fabricate a single station retractor durability testing prototype deploying the state-of-art in technology to cater the requirement of increasing the capacity of seat belt testing.
