Experience flexibility in simulation styles to suit your problems' needs: simulate within Adams, within the controls software or co- simulation.Connect your Adams model to block diagram models you've developed with control applications such as Easy5® or MATLAB®.Add a sophisticated controls representation to your Adams model.For example, using Adams Mechatronics in Adams Car, you can quickly create assemblies of vehicle systems including control systems, and then analyze them to understand their performance and behavior. Adams Mechatronics has been developed based on the Adams Controls functionality and contains modeling elements which transfer information to/from the control system.

Loads and forces computed by Adams simulations improve the accuracy of FEA by providing better assessment of how they vary throughout a full range of motion and operating environments.Īdams Mechatronics is a plug-in to Adams which can be used to easily incorporate control systems into mechanical models. Utilizing multibody dynamics solution technology, Adams runs nonlinear dynamics in a fraction of the time required by FEA solutions. Along with extensive analysis capabilities, Adams is optimized for large-scale problems, taking advantage of high performance computing environments. Engineers can evaluate and manage the complex interactions between disciplines including motion, structures, actuation, and controls to better optimize product designs for performance, safety, and comfort. Simulate "Real World" PhysicsĪs the world's most famous and widely used Multibody Dynamics (MBD) software, Adams improves engineering efficiency and reduces product development costs by enabling early system-level design validation. Mechanical, electrical, and other subsystems are validated against their specific requirements within the systems engineering process, but full-system testing and validation comes late, leading to rework and design changes that are riskier and more costly than those made early on. Finally, the impact speed is estimated with correspond to the exact pedestrian throwing distance.Product manufacturers often struggle to understand true system performance until very late in the design process. The relation curves and equations between pedestrian’s throwing distance and vehicle impact speed are established from regression analyses of the simulation data. Different impact speeds are discussed to predict the different throwing distance of the pedestrian. And more the model is introduced to simulate the collision in a real case of vehicle-pedestrian accident in Hangzhou. A multi-body dummy pedestrian model is established based on PC-CRASH programs, the features that represent the different parts of the pedestrian are defined such as geometry, mass, contact stiffness and coefficients of friction. In this paper, a methodology for simulation of vehicle-pedestrian accidents based on the multi-body dynamics is presented. However, it is difficult for traffic management department to reconstruct such kind of accident.
Vehicle-pedestrian collision is a major type traffic accident in China, which has been attracted close attention by people because of its high fatality rate.
