Nanoscale materials have become an active area of research due to the enhanced mechanical properties of the nanomaterials in comparison to their respective bulk materials. The effect that the size and...
Life Prediction Based on Transient Dynamics Analysis of Van Semi-trailer with Air Suspension System
van-body air suspension system transient dynamics
2011/2/23
The early fatigue damage in the van-body of the semi-trailer is often caused by the unique mechanical characteristics and the dynamic impact of the loads. The traditional finite element method with st...
Receptance Coupling for Tool Point Dynamics Prediction on Machine Tools
receptance coupling dynamics endmill chatter
2011/1/24
Chatter has been a primary obstacle to the successful implementation of high speed machining. The frequency response function(FRF) of the tool point is crucial for identification of chatter free cutti...

2010/8/20
The performance of the vehicle dynamics stability control system(DSC) is dominated by the accurate estimation of tire forces in real-time. The characteristics of tire forces are determined by tire dyn...
Classical diffusive dynamics for the quasiperiodic kicked rotor
Classical diffusive dynamics quasiperiodic kicked rotor quantum
2010/3/23
We study the classical dynamics of a quasiperiodic kicked rotor, whose quantum counterpart is known to be an equivalent of the 3D Anderson model. Using this correspondence allowed for a recent experim...
基于牛顿欧拉法的2UPS-2RPS并联机构逆动力学分析（Inverse Dynamics of a 2UPS-2RPS Parallel Mechanism by Newton-Euler Formulation）
并联机构 逆动力学 驱动力
2009/5/22
2UPS-2RPS为具有两种不同支链结构的4自由度并联机构，具有结构简单，制造成本低，控制容易等优点。由于自由度数目少于6，机构的支链不仅传递驱动力，同时还向末端提供约束力，因此在对机构动力学控制及尺度和截面参数动力学优化时，驱动力和约束力分析都是必要的。本文运用牛顿欧拉法建立了该机构的逆动力学方程。在给定动平台的运动规律和外力后，通过动力学方程求解得出所需驱动力和约束力矩，并给出仿真实例。
