Multi – Body Dynamics
Because of its versatility in analyzing a broad range of applications from robotics to computer animation, and from digital prototyping to virtual reality, dynamic simulation of multibody systems has grown in the past two decades to be an important tool for designing, prototyping, and simulating complex articulated mechanical systems. Bridging the gap between multibody dynamics and engineering applications DEP MBD team puts into perspective the importance of modeling in the dynamic simulation and solution of problems in the analysis that are being part of the entire process.
Our team is experienced in overcoming unique challenges, including the need to accurately model multibody interaction via joints, bearings, contact, gear systems, and other important constraints. Simultaneously we can incorporate flexible components and joints that may lead to failure due to large deformation or fatigue using linear, modes-based, and nonlinear representations, as well as material nonlinearities and contact, into MBD simulations to more accurately simulate the dynamic responses for a detailed component-level structural analyses.
Some of the analyses carried out for a crankshaft MBD includes:
Along with the rapid development of modern industry, the oil source is increasingly tense so the working efficiency of the engine and life is paid more and more attention. The mechanical strength of engines and its parts are also growing. As a core parts of the engine, the strength and stiffness of crankshaft has been the research emphasis for the designers. The main method is to analyze the dynamic characteristics of the crankshaft by effective means of virtual technology and simulation, so as to get multiple efficiency parameters of the crankshaft.
