Abstract:

In order to develop the automotive engine coolant hose products and detect its performance, by simulating actual condition, at which the coolant hose work, coolant hose highlow temperature vibration test system was set up. First of all, according to the actual vehicle driving conditions, the engine coolant hose vibration test system designed. and then place the test device into test cabin environment to proceed vibration test in different temperature at -40 ℃,23 ℃ and 70 ℃ respectively. The vibration test results of the hose outside diameter of the largest change rate at 23 ℃ is 15.96%, -40 ℃ low temperature is 17.68%, 70 ℃ is 19.22%.Experiments show that the high, low temperature vibration test is more suitable for product development, design and formulation of standard parameters.

Key words: vehicle test, coolant hose diameter, high-temperature, low-temperature, vibration, outside diameter change rate
