A link model which is composed with a fisherman's arm, a fishing rod, a line and, a Sweet fish are used in order to simulate a fishing system by using the Multi-body Dynamics. Pictures of the landing of the fish are taken by high speed camera in order to compare the orbit of the fish with the simulated one and the accuracy of the simulation is evaluated. Then simulation of two fishing rods which are good feeling and bad feeling of landing are performed to investigate the physical parameters of the fishing behavior in the fishing. As a result, difference of the parameters for the good and the bad fishing rods are clarified.

A partial but full-size mock-up test of practical steam-generator U-bend tubes in nuclear power plants has been carried out, where the test model has been set in a HFCF-123 fluid two-phase flow loop. U-bend tubes are supported with so-called "Anti-vibration Bars (AVB) ", which have two types of AVBs in Japan, 7-span type and 5-span one. Both types of AVBs have been examined and it is found that tubes with AVB supports shows no large amplitude vibration up to 150% flow rate to the practical condition. Basic data for the fluidelastic instability are obtained when some tubes have been set to be flexible at some contact points with AVBs.

In this paper, the engineering evaluation method of the crucian fishing rods is performed. Principal component analysis and multiple regression analysis are performed to the results of the questionnaire about the performance of crucian fishing rods. As a result, the performance evaluation index "stiffness・strength", "weight", "top stop" are obtained and the performance evaluation equations of the crucian fishing rods are established. It is cleared that these equations are enough practical in the sight of degree of accuracy. Then, the design of crucian fishing rod is performed by using FE model. The design of the rod with targeted performance is become possible by solving the optimization problem setting the diameter of the rod as the design parameters and the Principal component score as the evaluation function. It is thought that these analysis methods are applied to the tailored design of fishing rod based on the sensory requirement of angler.
