To study the influence of front seat parameters on rear seat passenger's safety when front crash happens, this paper uses MADYMO software to establish a rear seat passenger constraint model, which includes car bodies, safety belts and a 5% dummy for impact simulation. Using this model, the simulation values are close to the results of the vehicle impact test. The influence of design parameters including...
This paper presents an optimal controller for an Instantaneously Coupled System (ICS) which was designed by coordinating multiple lower-dimensional optimal controllers. We augmented subsystems of the ICS with coordination variables, and then used value functions to coordinate the augmented subsystems by managing tradeoffs of the coordination variables. We apply this method to humanoid walking and...
Passive rehabilitation robots are the auxiliary equipment which used to help patients recovering from diseases. In this paper, we addressed a lower limb 4-degree of freedom (4-DOF) model, proposed a lower limb rehabilitation mechanism. Based on MATLAB/Simulink software, analyze the displacement, speed and acceleration of fulcrums are analyzed. Experiment results verified that the simulation results...
In this paper the five dof manipulator has been established based on the kinetic model of manipulator, through the UG, will be built on solid modeling entity model simplified through good introduction to the ADAMS software ADAMS, establish the virtual prototype of manipulator, the dynamic simulation of the joint Angle and joint torque, angular velocity and Angle acceleration curves, analyzed the end...
The walking procedure of the cattle, Bostaurus, on a paddy field before spring plowing was captured with a high-speed video camera. The properties of the paddy soil used for tests and the geometrical configurations of the hooves of the cattle were examined. The geometrical configurations and motion postures of the cattle during walking on paddy field were analyzed, and the gait parameters were gained...
The geometrical configurations of the locust were obtained by using the stereomicroscope. The kinematics of the jumping process the locusts were analyzed from the high-speed photograph, and the jumping parameters of the locusts were gained. The characteristics of the locust during jumping were discussed. The dynamic model of the locust robot was established by the technology of virtual prototype....
In order to study damage of ancient buildings by the Wenchuan earthquake in China on 12th ,may 2008, we took Da-Xiong Palace which is 189 km far away from the epicenter as an example for analysis. Columns of the palace inclined very much by the earthquake. We used time-history method to simulate response of the palace to find out the main reason for the large inclination. According to characters of...
A camera orientation system has been developed to be used as an artificial eye e.g. in the head of humanoid robots or as a head-mounted gaze-driven camera orientation device. In this paper simulation experiments with natural eye movements, such as fixations, smooth pursuit and saccadic eye movements are carried out. The derived models are primary used to prove that the selected piezo-actuators are...
Tramcar is important railway conveying equipment in acclivitous shaft of mine. During conveying, tramcar and track often vibrate because there are some excitements. Intensive vibration often causes run-away tramcar accident, and causes deformation of tramcar body. The present paper develops a coupling vibration model to analyze the vibration characteristics of tramcar and track when tramcar goes through...
