Based on the principle of bionic hexapod, a 3D virtual prototype model of the bionic hexapod robot and the contact model between its feet and the ground are established by using MSC. ADAMS mechanical dynamics software to study the motion of the bionic hexapod robot on the horizontal ground. And then, the kinematics analysis of a single leg of the robot is made to realize the overall motion control...
Of the sensors that quantify motion, accelerometers are commonly available at low cost due to their widespread use. Whether embedded in other products or used by itself, it is used to measure movements across a wide range of intensities and frequencies but for normal biological applications, the range of physical movements is not vigorous. Proper use of accelerometers requires understanding of their...
To further study the crank-slider-CST protective device, the finite element models of car and truck with different kinds of low rear protective devices were built in VPG firstly. Then the full width rear-end crash simulation at the speed of 32Km/h was carried out in LS-DYNA. Finally, compared the acceleration, rebound velocity and inserting displacement of the front axis of the car. The simulation...
Nowadays the need for powerful hardware architectures, which allow for high throughput data analysis and calculus, is fundamental especially for biological applications. We have been focused on utilizing the Graphic Processing Unit (GPU) architectures of NVIDIA for accelerating a lipid bilayer simulation tool for biomembranes.
In the reliability prediction of the product with long life and high reliability, the step stress accelerated degradation test (SSADT) is commonly applied. With the motivation of predicting the product reliability most precisely, the problem of optimizing the test plans has drawn a lot of attentions in the application of SSADT. In this paper, the drift Brownian motion is selected as the degradation...
According to a new horizontal moving mechanism called `Side-Wheel Operating Simultaneously', the moving process of the high-speed & high acceleration stacker for starting and accelerating was simulated and analyzed with multi-body system method. The result showed that the stacker is able to accelerate stably and fast with the designed maximum acceleration and speed.
This paper introduces the integration of communication modelling into design modelling during the early stages of system development. It presents the modelling of flocking behaviour system in SystemC, which is emerging as a suitable language for designing and modelling. SystemC provides a consistent methodology for the design and refinement of complex digital systems. In this paper, a demonstrator...
We present a reduced order finite element (FE) algorithm suitable for real-time nonlinear simulation of soft tissues. A dynamic FE formulation with explicit time integration is employed. We demonstrate significant computation acceleration by performing the time integration in a low-dimensional generalised basis, generated from a set of a priori training simulations. The key mechanism for the acceleration...
Based on the first generation of hybrid electric city bus CA6110HEV developed by FAW (First Automobile Workshop) in China, the new generation of hybrid plug-in bus was designed, mainly including the parameters matching for the power-train and power sources. Then simulation platform were developed and established. The dynamic and economy performances were predicted based on the above work, results...
A forward simulation model of the energy- saving concrete mixer with hydraulic technology based on Matlab/Simulink is established in this paper. Parallel connection of hydraulic brake module and mechanical brake module is presented, which realizes the high recovery efficiency of brake energy on the premise of ride comfort and safety of the braking process. The simulation results show the effectiveness...
In this paper, based on a battery pure electric city bus, principle researches have been offered on the parameters matching of the power-train and main components. The vehicle system was designed integrated, and then simulation platform was developed and established. The dynamic and economy performance can be predicted based on the above work, results show that the designed pure electric city bus...
This work reports real-time soft-error rate (SER) testing of semiconductor static memories in both altitude and underground environments to separate the component of the SER induced by the cosmic rays (i.e. primarily by atmospheric neutrons) from that caused by on-chip radioactive impurities (alpha-particle emitters). Two European dedicated sites were used to perform long-term real-time measurements...
