摘要
以人体运动学、理论力学、人体测量学为基础,结合坦克驾驶员坐姿特点提出了一种计算人体各关节受力与力矩的三维人体生物力学模型,该模型能有效的处理关节位置和力矩约束.通过姿势分析和生物力学模型计算,并运用仿真分析软件分析评价虚拟驾驶员的关节力学负荷,结果显示坦克驾驶员腰部受力比其它关节受力大,拉操纵杆时腰部受力比生理弯曲引起的姿势负荷明显增大.
A three-dimensional biomechanical human model for calculate human joints＇ force and mo- ment is presented. In this model, the human kinematics, theoretical mechanics, anthropometry and tank driver＇ s sitting posture are considered. The handle constraints such as joint position limits and torque limits can be defined. Through analyzing sitting posture and calculating biomechanical model, the force of virtual driver＇ s joints is calculated by simulation analysis tool. The results show that the force of tank driver＇ s haunch is bigger than other joints, and the force is obviously increasing when operating joy stick.
