Customer correlated test development for heavy duty trailer truck components

Before a product is released to the market, it is passed on to certain tests. It is necessary to determine in advance how these tests are, what conditions they are, and how long they are. However, since the product does not put upon to the market and the product is in the development phase, it is hard to have precise information about the customer's usage conditions, frequency of use, and where the product can be used. For this reason, it is also difficult to make tests so as to corroborate customer usage. In this study, the development of customer correlated durability test for clutch system, cooling fan and the 16-speed heavy duty vehicle transmission will be explained. To do it we need to understand how the customer is using the vehicle. One way to understand customer usage is to collect data directly from the customer and the other method is to use and collect data from the test vehicle that runs on specified conditions and combining them with customer surveys. Direct customer data collection is a costly and lengthy process with legal challenges. For this reason, we will try to understand the use of the customer by running the test vehicle.
