The rigid body is defined as a continuum for which, under any physically possible motion , the distance between any pair of its points remains unchanged . The rigid body is a mathematical abstraction which models very accurately the behaviour of a wide variety of natural and man-made mechanical...
Walking, running, and sprinting: a three-dimensional analysis of kinematics and kinetics. Just as in running, the two-joint muscles acting at the hip and at the knee work to transfer energy efficiently between body segments. This can be seen in ... TF Novacheck - 《Instr Course Lect》 被...
1.The formulation of kinematics and dynamics of multibody system based on the fully Cartesian coordinates has an important advantagement in computational efficiency.用完全笛卡尔坐标描述多体系统的运动学和动力学在提高计算效率方面有突出优点。 2.Based on the fully Cartesian coordinates, a differential/algebra...

A three-dimensional (3D) CT technique was developed to analyze in vivo segmental carpal kinematics. Transverse CT data of the distal forearm, carpals and proximal metacarpals was acquired and 3D reconstructed in various wrist positions. Carpal kinematics were analyzed in two groups of 20 asymptomatic...
Kinematics Analysis and Optimization of Stepping Rotary Three-Dimensional Braiding Machine doi:10.1007/978-981-97-7887-4_57Due to its excellent performance, three-dimensional composites are an ideal choice for components in the aerospace and automotive fields. However, the need for smooth operation ...

Each patient was asked to walk barefoot, at a self-selected speed on an 8-m walking board. A minimum of 20 gait cycles were collected for each lower limb to evaluate consistency. Kinematics data were motion-captured using a 20-camera infrared motion analysis system (Santa Rosa, California, ...
The possibility of adding a redundant seventh LVDT has also been explored and improvements in accuracy are reported. The main advantages of this technique are its compact size, accuracy, and low overall cost. 展开 关键词: In vitro measurement 3-D joint motion rigid body kinematics sacroiliac ...
