标准摘要
[中文适用范围]： 测功机的测试条件范围应足以确定与车辆全范围操作相对应的主要操作特性。待确定的特征是： a．扭矩比与速比和输出速度； b.输入速度与速比和输出速度； C。效率与速比和输出速度； d.容量系数与速比和输出速度；和 e。输入扭矩与输入速度。 [外文原描述]： The range of test conditions on the dynamometer shall be sufficient to determine the primary operating characteristics corresponding to the full range of vehicle operations.The characteristics to be determined are:aTorque ratio versus speed ratio and output speedbInput speed versus speed ratio and output speedcEfficiency versus speed ratio and output speeddCapacity factor versus speed ratio and output speedeInput torque versus input speedNOTE: For more information about these characteristics and the design of hydrodynamic drives, refer to “Design Practices: Passenger Car Automatic Transmissions,” SAE Advances in Engineering, AE-18 (Third Ed.) or AE-29 (Fourth Ed.).Cross Reference:
