翻訳と辞書　辞書検索 [ 開発暫定版 ] スポンサード リンク Hammer blow ： ウィキペディア英語版 Hammer blow Hammer blow, in rail terminology, refers to a vertical force which alternately adds to and subtracts from the locomotive's weight on a wheel. It is transferred to the track by the driving wheels〔"The Theory of Machines" Thomas Bevan, Longmans, Green and Co. 1945, p.457〕 of many steam locomotives. It is an out-of-balance force on the wheel (known as overbalance〔"Steam Locomotive Rail Wheel Dynamics Part 2: Mechanical balancing of steam locomotives, Fengler, Odom, Rhodes, Coalition for Sustainable Rail〕). It is the result of a compromise when a locomotive's wheels are unbalanced to off-set horizontal reciprocating masses, such as connecting rods and pistons, to improve the ride. The hammer blow may cause damage to the locomotive and track if the wheel/rail force is high enough. 'Dynamic augment' is the US term for the same force.〔"The Steam Locomotive", Ralph Johnson,Simmons-Boardman Books, Inc. 2002, Ch. XVI〕 == Principles == The addition of extra weights on the wheels reduces the unbalanced reciprocating forces on the locomotive but causes it to be out of balance vertically creating hammer blow.〔 Streeter, Tony: 'Testing the Limit' (''Steam Railway Magazine'': 2007, 336), pp. 85〕 Locomotives were balanced to their individual cases, especially if several of the same design were constructed (a class).〔 Each class member was balanced for its normal operating speed.〔 Between 40% and 50% of the reciprocating weights on each side were balanced by rotating weights in the wheels.〔 抄文引用元・出典: フリー百科事典『 ウィキペディア（Wikipedia）』 ■ウィキペディアで「Hammer blow」の詳細全文を読む スポンサード リンク 翻訳と辞書 : 翻訳のためのインターネットリソース Copyright(C) kotoba.ne.jp 1997-2016.
