概要: This paper discusses a method for the optimal active vibration control of a plate using piezoelectric actuators. The analytical results under the optimal control were obtained by combining the eigenfunction procedure and the optimal active control theory. Numerical calculations were carried out for a clamped circular plate with concentrated masses which was controlled by bending moments generated by the piezoelectric actuators. It is confirmed that there is an optimal location for the actuator in each mode. 続きを見る

概要: This study aims to clarify the importance of chamber wall temperature in the knocking characteristics of a spark-ignition engine. To vary the chamber wall temperature, two procedures were used, one is to change the coolant temperature and the other is to raise the exhaust valve surface temperature by substituting a ceramic surface layer for the original steel layer. Although the coolant temperature change had no influence on the flame propagation process, it fairly affected the knocking process, such as mean knock intensity and mean knock occurrence timing. This is caused by both the change of bulk mixture temperature of the end gas and the temperature uniformity within the end gas region. Cycle-by-cycle based knocking behaviour can also be influenced by the coolant temperature, which is considered to be based on the temperature uniformity in the whole chamber region. Exhaust valve surface temperature change did not affect any knocking characteristics. It suggests the importance of the wall temperature in the end gas region. 続きを見る

概要: A new combustion system called a jet-mixing-type combustor was designed to obtain a nonluminous blue flame of a kerosine spray. A spray was injected by a conventional-type swirl atomizer into the combustor and combustion air was introduced through a baffle plate with 16 inlet holes. The principle of this combustion method was revealed as a prompt mixing of the air and the spray, which was achieved by a high-speed air jet. The combustion characteristics such as combustion stability, temperature distribution and exhaust emissions were compared with a conventional swirler-type combustor. NO and THC emission levels exhausted from nonluminous kerosine flame were lower than those exhausted from the swirler-type combustor. 続きを見る

概要: The running vibration of a bogie car is considerably affected by its operation speed. This paper describes the results of a calculation analysis on the vertical vibration of a Shinkansen electric car at the speed range up to 510 km/h, assuming a drastic speed-up of the Shinkansen. The vibration of each natural modes, except the body-bending mode, tends to increase uniformly with the operation speed. The vibration of the first body-bending mode varies greatly due to the averaging effects of the track roughness through the length between truck centers in the car, and it deteriorates the riding comfort further in the speed ranges near 270 km/h and higher than 450 km/h. As an example, the flexural rigidity of the car body is examined to determine countermeasures suitable for 270 km/h operation. 続きを見る
