Acceleration durability test and evaluation method of fuel cell bus based on user association

The reliable durability of fuel cell vehicles is the key to improve its market share, and the accelerated durability test site based on the structural characteristics of fuel cell vehicles under the user's use scenario is the main verification method. Based on typical fuel cell bus driving load data and test site driving load data, this paper uses six cent, strain and acceleration sensors to collect the load spectrum of social pavement and test site, and adopts the equal damage principle to carry out the life cycle load spectrum extrapolation and multi-objective optimization model solving methods, so as to establish the durability test method of fuel cell bus testing site.
