摘　　要：确定潜器纵向运动阻力试验方案,通过改变速度的不同水平来测试对应阻力。然后设计测试装置、卷扬机构、单片机的模块结构和主要功能,编写试验程序。用模拟潜器进行试验,获得大量数据,用最小二乘原理进行回归分析,得到回归方程(经验公式)。经过显著性检验、经验类比和方差计算,验证回归方程具有很高的可依赖性,从而证明本文设计的潜器纵向运动阻力试验的试验方法及试验装置技术可靠,具有实际应用价值。We consult the resistance test of model in the calm and tranquil water, we have defined the way of test, that is submersible body is pulled by a step motor in a artificial pool and then we define that change velocity to test resistance. We have selected sampling frequency. Base on the mean of sensor have been designed. Supporting form of spring part is defined. Step motor lifting mechanism has been made. Controlling parts of test system are designed, and then compile programs, and then the rest instrument will be used in the test are prepared. Now start the work to test resistance longitudinal force. Thousands of data have been taken for analysis of regression. Not only is regression equation achieved, but also it is corroborated right, that is practicable test plan is established. It can be used for test resistance perpendicular force.
