[Abstract]:In order to establish a widely applicable test method for inertial shrinkage ratio of friction materials, a preliminary study was carried out on the test equipment and flow chart of inertial shrinkage test. The basic characteristics of the inertial shrinkage test device and the specific parameters of the friction disc and the friction material sample block which can be used for the inertial shrinkage test are given, and the concepts of velocity and pressure shrinkage coefficient are put forward. Based on the bench test standard ISO-26867, a suggested test procedure for inertial shrinkage test is proposed. An experimental study was carried out on the inertial shrinkage ratio test rig which accords with the above basic characteristics and was compared with the bench test of the same batch friction sheet. The results show that the experimental results obtained from the experimental process are comparable to those of the bench test, which proves the validity of the proposed test equipment and the test process, and provides a reference for the establishment of inertia test method for friction materials.
