Abstract�� Whether or not to compensate the oil pressure because of lift crane velocity reasonably, i.e., the velocity compensation was thought to be the key to obtain accurate dynamic weighing about loaders. After the method of dynamic weighing was given, the parameter inferring course of least square support vector machines (LS-SVM) within Bayesian evidence framework was introduced. Then the frame model of velocity compensation based on LS-SVM was given, and the means of velocity compensation and the course of weight computing were introduced in detail. Test results indicate that using LS-SVM within Bayesian evidence framework for solving velocity compensation, a relative measuring error within 1% can be obtained, which verifies that the validity of the method.
