环氧树脂做成的单拐和双拐曲轴模型上有自由扭转和约束扭转负荷,在曲柄销上有径向力和切向力,在主轴颈上有轴向力、径向力和切向力偶。多数情况是用应力冻结方法固定变形,这比用直接加载更能详细和精确地进行测量。对于一个基本曲拐,在56个试验中,研究了曲柄臂形状变化的影响、主轴颈和曲柄销扭转角、曲柄臂开度以及主轴颈的倾斜度和位移。英国内燃机研究协会预测扭转变形的试验方法表明是可靠的。径向面弯曲变形可以用应变能计算方法来预测。
Epoxy resin made of single-and double-crank crankshaft model has the freedom to reverse and constrain the torsional load on the crank pin radial force and tangential force on the main journal have axial force, radial force and tangential Even couple. In most cases, the deformation is fixed by the stress-freezing method, which is more detailed and accurate than direct loading. For a basic crank, in 56 experiments, the effects of changes in the shape of the crank arm, the twist angle of the main journal and crank pin, the opening of the crank arm, and the inclination and displacement of the main journal were studied. The British Society of Internal Combustion Engineers test method for predicting torsional deformation shows that it is reliable. Radial surface bending deformation can be calculated using the strain energy to predict.
