Sensitivity analysis of peripheral parameters in three dimentional nano-manipulation by using HK model

Nano particle manipulation is composed of two phases. First phase is critical force and time investigations and the second phase is nano particle motion and displacements. In this paper the first phase of nano particle manipulation was investigated. Critical force is the amount of force required for overcoming the friction and surface adhision forces. Also critical time is the duration for partical to change from static to dynamic state. Two noticeable categories of parameters are chiefly effecting on two significant factors: 1- peripheral parameters and 2- dimensional parameters. In this paper by utilizing sensitivity analysis, which A-fest method is one of them, and HK precise friction model effect of peripheral parameters on critical rolling's time and force was studied. Surface energy, work adhision, elastic modulus of needle and particle and poissan coefficients of needle and particle, are the studied peripheral parameters. With nano particle considered to be rigid and without its deformation, elastic modulus of particle and needle was known as the most effective factor on critical rolling force and time in x-axis direction and y-axis direction in nano manipulation using Hk model respectively.
