Comparing the modified tooth profile with conventional one by tests and calculations , the finite element analysis is proved accurate and the modified profile shows lower stresses than conventional one , either in dedendum or in tooth \'s midposition .

通过对通用齿形和改进齿形的对比实验和计算，证实了有限元方法是较准确的，改进齿形无论在齿腰还是在齿根的应力都低于通用齿形。
