In this paper, we attempt to carry out the dynamic analysis of a motor vehicle, using the virtual prototype developed with the MBS (Multi-Body Systems) software ADAMS. The virtual prototype includes the front and the rear suspension subsystems, the steering subsystem, and the car body subsystem. The experiment designed is one frequently carried by the automotive manufacturers, namely passing over bumps. The connection between wheels (tires) and road (ground) is made using contact forces, which allow modelling how adjacent bodies interact with one another when they collide during the simulation. On the virtual prototype, several measurements have been realized having in view to evaluate the dynamic behaviour of the vehicle.

Sonic drilling is a novel sampling technology applied in many fields. Based on SolidWorks software, a dynamics virtual prototyping is utilized to develop a physical sonic driller by demonstrating collision detection and optimizing overall layout and key component structures. Key hydraulic and structural parameters are optimized using a mathematical model. Search for the optimized parameters and operating conditions for this multi-body mechanical system is conducted experimentally. The practical results show that the virtual prototype technology not only shortens the design cycle but also improves the quality of the conventional design. The new sonic driller designed by this method is both environmentally friendly and smarter.

The menisci have an important multifunctional role in the human knee. They protect the joint articular cartilage (by acting as a buffer between femoral and tibial surfaces while loading), provide joint lubrication, and increase joint stability (by providing congruity between femoral and tibial articular surfaces) [1]. The menisci also effectively distribute contact forces over the articular surfaces by increasing the contact surface of the joint [2].

Train derailments in railway switches are becoming more and more common, which have caused serious casualties and economic losses. Most previous studies ignored the derailment mechanism when vehicles pass through the turnout. With this consideration, this work aims to research the 3D derailment coefficient limit and passing performance in turnouts through the quasi-static analysis and multi-body dynamic simulation. The proposed derailment criteria have considered the influence of creep force and wheelset yaw angle. Results show that there are two derailing stages in switch panel, which are climbing the switch rail and stock rail, respectively. The 3D derailment coefficient limit at the region of top width 5 mm to 20 mm is much lower than the main track rail, which shows that wheels are more likely to derail in this area. The curve radius before the switch rail is suggested to be set as 350 m. When the curve radius before turnout is 65 m, the length of the straight line between the curve and turnout needs to be larger than 3 m. This work can provide a good understanding of the derailment limit and give guidance to set safety criteria when vehicles pass through the turnout.
