CRRC Meishan Co., Ltd of China continues to make improvements to their ZJX-2 Type radial truck through mathematical modeling and developmental testing at TTCI towards the end goal of AAR certification. CRRC Meishan engineers were trained in the use of NUCARS®, TTCI’s dynamic modeling software, and utilized these skills to make performance improvements. Meishan engineers made suspension modifications based on model predictions, and in most cases modeling trends showed improved performance when measured on track during testing.
