Friction analyses of the rocket sled system

摘要

摘要: 根据火箭橇动态试验非线性和非定常特点，以及火箭橇与轨道的摩擦特性，对某型火箭橇系统进行了动力学分析、建模和流场数值模拟，界定了不同运动状态的动力学特点，得到了系统的气动力特性。研究结果表明：在60～90m/s速度条件下，该型火箭橇阻力系数约为0.58，升力系数约为0.003，气动力主要表现为气动阻力，升力与火箭橇自重相比相对较小，约占自重的0.5%～1.2%。同时结果表明，火箭橇运动速度是影响摩擦因数的主要因素，摩擦因数随运动速度的增大而减小。在数值模拟和试验数据基础上，确定了幂函数形式的摩擦因数计算公式，公式以运动速度为底数，系数为2.554，指数为-0.756。并在多种工况下，对火箭橇运动参数进行预测和验证，与试验数据符合良好。

Abstract: Based on the nonlinear and unsteady motion and friction characteristics analyses of the rocket sled in dynamic testing, the dynamic modeling and numerical simulation of the rocket sled were carried out. Meanwhile, the dynamic and aerodynamic characteristics of the rocket sled in different motion states were analyzed. The results showed that the drag coefficient was about 0.58, and the lift coefficient was about 0.003 during the velocity range from 60m/s to 90m/s. The aerodynamic force of the rocket sled mainly manifested as drag force, and the lift was less than the rocket sled weight, about 0.5%-1.2% of the weight. On the other hand, sliding velocity was the main affecting factor of the friction coefficient. With the increase of the sliding velocity, the friction coefficient decreased. Considering the results from both simulation and tests, the function of friction coefficient in terms of velocity was established in the power form with a coefficient of 2.554, and an exponent of -0.756. The predictive values of the rocket sled calculated by the friction coefficient formula under different conditions agreed well with the experimental data.
