The spectrum of broadband random vibration contains rich frequency content and continuous feature, which makes it more accurate to simulate the vibration environment of the vehicle compared with the traditional program block fatigue test, so as to more accurately verify the durability of components. However, there are few studies on the compiling method of broadband random vibration spectrum. In this paper, taking the development of random vibration spectrum of integrated electronic brake (IPB) as an example, based on Lalanne’s damage equivalent in frequency domain theory, combined with the vibration intensity estimation method of shock response spectrum (SRS) and extreme response spectrum (ERS), a set of design method of random vibration spectrum is proposed, and the rationality and correctness of the method are proved by practical application, which could serve as a development tool for other similar verification.
