In this study, dust particle sizes and content were analyzed, and wear tests were conducted with silica and alumina to investigate the wear characteristics of rubber seal material in an automobile chassis system. The following conclusions were obtained: The main component of dust on the rural road was silica. On the urban road and highway, the main components were alumina and silica. On the urban road, various components such as Mg, Fe, and Ca were found on lumps of dust compared to the rural road. On the rural roads, the sizes of dust particles were larger than those on the urban road. The range of dust size for all road conditions was 40 micron 75 micron. The primary damage mechanism of the rubber seal material was abrasive wear. Increasing the amount of silica flowing into the chassis system increased the wear volume of the rubber seal. The critical silica-to-water ratio was 1.5 g/10 ml. Increasing the size of dust particles resulted in increased wear volume. In the wear test using the composite dust with alumina (1 micron) and silica (0.8 micron), by increasing the amount of silica, the wear volumes of the rubber seal decreased. Using composite dust with alumina (1 micron) and silica (26.6 micron), the wear volume of the rubber seal increased. The larger, soft dust particles resulted in more wear on the rubber seal than the smaller, hard dust particles.
