Introduction The vibration problem of high-pressure pipeline conveying fluid is one of hot issues concerned by many scholars for long term, which not only has important research value in theory, but also has extensive engineering background.
Shield machine is a typical high-power engineering equipment, which contains a number of complex hydraulic subsystem, and the distance of the hydraulic pipeline between its actuator and the power source is long, and the vibration phenomenon induced by the effect of fluid-solid coupling is very obvious.
The material of hydraulic long pipeline is the seamless steel tube, the hydraulic oil is the lightweight metal hydraulic oil, the system pressure is set to 30Mpa, and other pipeline parameters are shown in Table 1: Table 1 Main parameters of pipe conveying fluid and the fluid Pipeline Length L=8000[mm] Inter diamater R=9.5[mm] Wall thickness δ=3[mm] Elastic modulus E=210[Gpa] Mass density ρf=7800[kg/m3] Paisson ratio γ=0.3 Damping ratio ζ=0.02 Hydraulic oil Bulk modulus K=1.6[Gpa] Mass density ρf=890[kg/m3] Experimental Modal Analysis Experimental modal analysis of long straight pipeline without support in the middle.

The key to dryspinning CNT yarns is the availability of 'drawable' forests.
The term core-spun covers constructions in which the core comprises a significant proportion of the total material in the yarn.
Mechanical Properties: Of key interest is the effect of yarn twist on tensile strength and results for a range of twist angles as shown in Fig. 9. 0 200 400 600 800 1000 0 2 04 06 08 0 Twist Angle/degree Yarn Strength/MPa Data Hearle's Function Figure 9: The strength of dry-spun CNT yarns as a function of the twist angle.

Nano particles made of high thermal conductivity materials and their increased fraction in pure fluids enhance the thermal conductivity of the nano fluid [3&4].
The thermal conductivity of nanofluids varies with the size, material of nanoparticles as well as base fluids.
The agglomeration of nano particles is a key issue which is to be avoided in the nano fluids.
