Compared with the spacecraft instrumentation, the ground air disturbance, the unsteady aerodynamic flow on crossing event and inside tunnel impose more challenges on the head design of HSR trains.
The disturbance torques imparted by space environment are analyzed, which include gravity gradient torque, solar pressure torque, aerodynamic torque and magnetic torque.
对作用在卫星上的各种空间环境力矩进行了分析，包括重力梯度力矩、太阳光压力矩、气动力矩、剩磁力矩等。
