摘要
In order to control the cross? link forces and the vibration frequencies of the test bed of the full channel gas within the allowable ranges, the analyses of forces and deformation of the test bed was done, for the variously restrained elastic movable frame and the rigid one, the vibration frequencies were computed respectively by means of the methods of mechanics of materials, elasticity and vibration mechanics, the cross link forces and the vibration frequencies of the test bed were tested. The results of theoretical computation comparatively approach the experimental results. The computational methods could be used to availably estimate the design parameters relevant to the test bed of the full channel gas.
为了把全通道燃气试验台交联力及振动频率控制在许可范围 ,用材料力学、弹性力学和振动力学的方法对试验台进行了受力与变形分析 ,分别就弹性动架和刚性动架在不同约束下进行了振动计算 ,并对实验台的交联力和振动频率进行了实验测试 .理论计算和实验结果比较接近 .
