The invention relates to a program file running method and device, a terminal and a storage medium, and belongs to the technical field of computers. The method comprises the steps of obtaining a preset path; When the first program file of the application program is generated, sending a transmission instruction to the second terminal through communication connection with the second terminal, wherein the transmission instruction carries the first program file, and the transmission instruction is used for indicating to store the first program file in a preset storage space; And sending a runninginstruction to the second terminal through the communication connection, the running instruction being used for indicating the second terminal to run the first program file stored in the preset storage space. Interaction is carried out through communication connection established between the first terminal and the second terminal. The first program file can be stored in the preset storage space, the second terminal can be controlled to automatically run the first program file, technicians do not need to execute multi-step operation on the first terminal and the second terminal respectively, operation is simplified, and consumed manpower resources are reduced.

The present invention proposes a method and device for synchronously testing the torque coefficient and friction of a robot's joint motor. The method includes: calculating the analytical expression of the driving torque of the driving joint of the robot according to the dynamic model of the robot and the structural parameters of the robot; The experimental data is input into the analytical expression of the driving torque to obtain the forward torque and reverse torque, and the driving current is fitted to obtain the slope and intercept of the fitted linear function at different experimental positions; combined with the ratio of the reduction ratio of the joint to be tested to obtain the The motor torque coefficient when the joint is moving forward and reverse, and the intercept is taken as the opposite number to obtain the friction coefficient when the joint to be tested is moving forward and reverse; calculate the motor torque coefficient and friction coefficient of different experimental positions The average value is used to obtain the target torque coefficient and target friction value of the joint to be tested during forward and reverse motion. Thus, the synchronous test of the joint motor torque coefficient and the forward and reverse friction coefficient is realized, and the test accuracy is improved.

The invention discloses a device for synchronously testing a reciprocating type friction power generation output property and a friction coefficient. A to-be-tested upper friction pair is arranged atthe front end, which is connected with a cantilever beam, of a cantilever beam supporting rack; a strain gage is arranged on the cantilever beam; a lower friction pair is arranged on a moving block ifa magnetic shaft linear motor and is positioned under the upper friction pair; the lower friction pair which is driven by the magnetic shaft linear motor to linearly move in a reciprocating manner relative to the static upper friction pair; current and voltage signals of friction power generation are output to a control and test computer; and meanwhile, the strain gage synchronously outputs the friction signals of the upper friction pair and the lower friction pair to the control and test computer. Because the control and test computer simultaneously acquires the current and voltage signals generated by friction power generation of the upper friction pair and the lower friction pair and friction signals, synchronous test on the friction power generation output property and the friction coefficient is realized; influence of interface friction behaviors to the friction power generation output property is discovered favorably; and the mechanism of action of the interface friction behaviors to an electric output property is facilitated.
