This work presents models and simulations of a numerical strategy for a time and cost-efficient virtual product development of a novel passive safety restraint concept for motorcycles. It combines multiple individual development tasks in an...
State estimator based on an indirect Kalman filter for a hydraulically actuated multibody system [0.03%]

Suraj Jaiswal et al.
In multibody system dynamics, the equations of motion are often coupled with systems of other physical nature, such as hydraulics. To infer the real dynamical state of such a coupled multibody system at any instant of time, information fusi...
Frame loads accuracy assessment of semianalytical multibody dynamic simulation methods of a recreational vehicle [0.03%]
RV半解析多体动力学仿真方法的架荷精度评估

Nicolas Joubert et al.
The design of a vehicle frame is largely dependent on the loads applied on the suspension and heavy parts mounting points. These loads can either be estimated through full analytical multibody dynamic simulations, or from semi-analytical si...
Simulation of multibody systems with servo constraints through optimal control [0.03%]
基于最优控制的伺服约束多体系统仿真研究

We consider mechanical systems where the dynamics are partially constrained to prescribed trajectories. An example for such a system is a building crane with a load and the requirement that the load moves on a certain path. Enforcing this c...
On the use of absolute interface coordinates in the floating frame of reference formulation for flexible multibody dynamics [0.03%]
