  • Research and development of automotive hydraulic brake hose has been carried out for domestic production. Four different trial products have been developed according to different design factors, and designated as Lot.. 1 through Lot. 4 respectively. Eleven kinds of static and dynamic performance tests have been conducted on each sample product of Lot. number, and the trial product by the Lot. 2 design factors was found to meet all the test specifications. Therefore, the automotive hydraulic brake hose could be localized in Korea.

  • Environmental factors for automotive consist of temperature, humidity, vibration(sine & random), gas, an electrical load and so on. These environmental factors are impressed in a automotive. Dependability is essential requirement in many electronic parts. Among components of automotive, the connector connecting electrical signals is one of the most important parts. Automotive -connector is inspected according to each manufacturer's test standard in which dependability should be considered. This paper aims to verify that current test standard is suitable for dependability, and present an inductive life test for automotive connector based on the field data in use-condition.

  • This paper introduces experimental results of whole-body vibration exposed through the contact area between automotive seat and human body. Such vibration experiment was carried out for five automotive seats in use and four Korean individuals. Interestingly, the quantitative assessment of the ride values of the tested seats do not only enable us to judge the footnotes the Korean technology in automotive seat has left so far, but also lead to the systematic way of improving their ride quality, in addition in Korean automotive seats raised in this paper.
