In order to evaluate the injury caused by vibration, the packaged Malaysian carambola was vibrated by the electro-dynamic shaker as the trip from Tainan county to Taipei city. The simulation of random vibration controlled by random profile of a small-type agricultural transporter in the conditions of regular tire pressure, farm road, 400 kg loading and velocity at 8.5 km/h ran for 20 minutes. The following procedure was a 20-minute mountain road trip and a 4.5 hr-trip on high way. Finally, a 30-minute trip was on the urban road.

An equal cross-section blade was investigated and a finite element model was built parametrically. Geometrical parameters (such as length, width and thickness), material parameters (such as young's modulus and density) and speed of blade were considered as input random variables while the static frequencies and dynamic frequencies were output random variables. Combining the finite element method, response surface method and Monte Carlo method, the statistical properties and cumulative distribution functions of static frequencies and dynamic frequencies were obtained. Probability sensitivities analysis, which combined the slope of the gradient and the width of the scatter range of the random input variables, was applied to quantitatively evaluate the sensitivities of static frequencies and dynamic frequencies with respect to the random variables. The Scatter plots of structural responses with respect to the random input variables were illustrated how to adjust the values of the static frequencies and dynamic frequencies by changing input random variables.
