Abstract

In this article the design and the development of spool type PIN PULLER mechanism from concept model to engineering model was expressed. At first, present models and designs were investigated and the conceptual design was based on positive aspects of these models and in order to better study the operation of mechanism, the concept model was built 5 times bigger than the real model. After this model the pre-engineering model with 350N pulling force was designed and built. It was tried to reduce the operational defects of concept model like fuse operation and the rupture of warping wire, in the pre-engineering model. Assembling of the model was carried out with special tools and operation test carried out in room temperature. In the engineering model pulling force was increased to 500 N and the material of inside parts was changed due to special electrical and mechanical conditions. Temperature and atmospheric test conditions were considered in the last model and the model was prepared to pass all qualification tests. VIBRATION TESTS and also Temperature tests were performed in vacuum chamber with respect to space standards. Reliability calculations were done on each PIN PULLER parts and at last reliability of whole PIN PULLER system were obtained.
