舰艇抗冲击试验自由场压力传感器布放机构设计分析
|
摘要
[目的]为解决舰艇在动态抗冲击试验中自由场压力传感器的布放问题,[方法]基于计算多体动力学理论,结合计算流体力学,设计自由场压力传感器布放机构。在布放机构中,布放杆件的设计需考虑截面形状、截面直径等参数的影响,并通过结构动力学数值方法进行强度校核。[结果]结果表明,该布放机构满足试验需求,布放杆件在使用碳纤维材料时易于操作,且将其布放在舰艇舷侧较为安全。当布放杆件截面直径大于35mm时,水流阻力迅速增大。[结论]文中设计、建模、校核及分析方法不失一般性,可应用于其他类似机械结构。
[Objectives]In order to solve the problem of free-field pressure sensor laying in dynamic anti-shock test of warship,[Methods]based on the theory of computational multi-body dynamics and fluid dynamics,the laying mechanism of free-field pressure sensor is designed. the influence of the parameters such as shape and diameter of cross section of laying mechanism are considered in the design,and the truss strength is checked by structural mechanics numerical method.[Results]The results show that the performance of laying mechanism can satisfy test requirement,and a truss made of carbon fiber is easier to operate and it is safer when installed at boardside. the flow resistance of truss increases dramatically when its diameter is greater than 35 mm.[Conclusions]without loss of generality,the design,modeling,checking and the analysis method in this paper can be used in other similar mechanical structures.
