The coupler is used to connect the vehicles, and to transfer and ease longitudinal force and impact force generated by the train running or shunting operation; hence it plays a vital role on vehicle-running safety. The parts of coupler are shaped by casting forming, with some forming error. The process of unlock, full open and lock, (three postures operation) are realized through the motion collision of these components. The forming error will influence the accuracy of coupler motion. However, there is no established theory or techniques to support the research towards the reliability of the motion. By making use of RecurDyn, simulation software for the 13 type coupler, authors carried out multi-body kinematics and dynamics modeling and simulation analysis, and predicted the up-lifter rod max not extract angle when the coupler is unlock with forming error. Meanwhile, authors established a basis process which contains construction and analysis of contact impact mechanism model, simulation geometry modeling, multi-body kinematics dynamics model and simulation analysis. All the efforts lead to one conclusion: the max up-lifter rod not extract angle is 25.5°,when the coupler is unlock. The outcome provides a simulation analysis method for predicting the motion veracity of railway freight car coupler with the features of space mechanism.

X-PLY Corrugated Paperboard is a new type of cushioning packaging materials, which has a light weight, strength and stiffness and other advantages, usually be made into cushioning pads (pieces) and used in the field of logistics and transport packaging to protecting internal product from shock and vibration. In the actual logistics process,external vibration excitation is often caused package resonance and lead to final damage of the package, so understanding the package natural frequencies and mode shapes, which can avoid package resonance factors causing unnecessary losses. By using of Lanczos modal analysis method in ANAYS simulation software, we obtains the first-fourth natural frequency and vibration mode of X-PLY (A) corrugated paperboard cushion pads under three different static stress. By compared simulation results with the previous experimental results, it can be referenced for the promotion and application of X-PLY corrugated board in the field of Cushioning packaging.

The geometric models of the hydraulic turnover device are constructed by using three -dimensional modeling software UG, and then they are induced into simulation software ADAMS by a sharing data format. By using ADAMS, models are further simplified and the virtual prototype is established. By using the associated model, the simulation of the hydraulic turnover device is analyzed in ADAMS. Compared with the traditional methods of using physical prototypes, the movement processes and relevant parameters of the hydraulic turnover device can be effectively obtained by means of this method. Furthermore, the quality of the constraint relations between the parts is very important in terms of the accuracy of the model simulation analysis. This simulation results accord with the practical situation, which indicates that the operation is stable and the efficiency is high. It provides a theoretical basis for the practical design of the hydraulic turnover device, which shows that the combination of ADAMS and UG works well.

Based on the analysis of a typical elevator for car hydraulic system, a general modular simulation model is established. Through the case study of initial cavity volume and load change different effects on the dynamic performance of hydraulic system, the conclusion is found that the increase in initial cavity volume and load are conducive to reducing the hydraulic impact at the starting moment, but have an adverse effect on the dynamic performance at the stopping moment, and that the time to reach the steady state increases.
