When working, tower crane is affected by natural environment and is subjected to complex various loads. So it is not very easy to analyze its dynamic performance at system level. Some researchers have done some work as to simulation and analysis of tower crane, in order to study its dynamic performance. While much of their work based on grid body model but not flexible body model. This paper used SolidWorks and ADAMS to build the virtual prototype of a tower crane based on ADAMS flexible body. After the co-simulation, which joined ADAMS with SolidWorks, force of the connection between tower crane base and the strengthened section of the crane was recorded and analyzed. And so was the acceleration of the tower crane’s lifting rig. Succeeding in the application of Virtual Prototyping Technology based on ADAMS flexible body, this study can be used to direct the work, operation and fault diagnosis of tower crane, and lay a basis for further studies.

Virtual prototyping technology as a key technology for agile manufacturing can deal with multidisciplinary knowledge across different fields. In the complex product development process, the exchange between heterogeneous data in heterogeneous environment is a universal problem encountered, which increases the complexity of collaborative parallel design of virtual prototype. Taking the product models as carriers and the different function requirements as clues, the knowledge structure and expression of product information in various fields was studied. By adopting component object model technology, direct geometry access technology, behavioural modeling technology and parametric design thinking, the interaction among tools in various function units was realized, and the effective integration of information and function in multi-fields was accomplished, the parameter-driven virtual prototype architecture of complex product based on the integration of information and function was created.

In order to analyze the performance of a certain FSAE racing car with rear wing at different attack angles by virtual prototyping technology. The multi-body model of a FSAE racing car which takes non-linear factors into consideration was built by applying ADAMS/Car. The correctness of the model is verified by comparison with the actual experiment result. By the simulation of the air resistance and lift characteristics of the rear wing, a feasible method to building the aerodynamic characteristics of the rear wing in multi-body model was proposed. Based on these, the crosswind stability of FSAE racing car with rear wing at different attack angles was analyzed, the result shows that the effect of crosswind is reduced with the increase of the attack angle of the rear wing.

Effective reuse and integration of multidiscipline model resources is a key issue and challenge in the Virtual Prototyping for Complex Products. Based on the Meta Object Facility and Component-based Modeling, This paper proposes a new component-based Meta Modeling Framework (M2F) of Complex Product Virtual Prototyping as a solution, providing the model specifications for each abstract layer (CAP model, CIM model and High-level model) in the framework. M2F enables multi-layered abstraction of those isomerism models in Complex Product Virtual Prototype and facilitates the unified modeling, reuse and integration of models. A case study about typical complex product indicates this approach not only makes the system-level modeling of virtual prototype easy, but also improves the reusability of component models. At the end of this paper, conclusion and future works are given.
