【Equipment introduction】
This equipment is mainly used to verify brake hoses under actual vehicle operating conditions, including complex service environments such as ambient temperature, left-right swinging and linear vibration. It is used to test whether automotive pressure-bearing parts can complete the number of cycles specified by relevant standards under given working conditions.
【Test items】
It is mainly aimed at the verification of brake hoses under actual vehicle working conditions, including complex environments such as ambient temperature, left-right swing and linear vibration, to test whether automobile pressure-bearing parts can complete the cycle times specified by the standard under specific conditions.
