Abstract

The invention relates to the technical field of industrial testing, and discloses load simulation equipment. The load simulation equipment comprises a main control panel, an auxiliary power supply, a control loop, a power resistor and a loading major loop. The main control panel comprises a control circuit, a current sampling circuit, a voltage sampling circuit, a soft starting circuit, a constant current drive circuit and an over-current protection circuit. The auxiliary power supply is controlled by the control circuit to supply constant currents to the loading major loop after passing through the power resistor, the current sampling circuit, the voltage sampling circuit, the over-current protection circuit, the soft starting circuit and the constant current drive circuit, and the control loop controls the control circuit through input of users. The load simulation equipment can test the constant current simulation performance of a load.

Description

technical field [0001] The invention relates to the technical field of industrial testing, in particular to a simulated load device. Background technique [0002] In contemporary society, mechanical equipment such as motors as the driving source abounds. This type of mechanical equipment uses the motor to drive the actuator to work directly or through a mechanical transmission device. The energy used is simple, and the working speed of the actuator can vary widely. It has the characteristics of high efficiency, high positioning accuracy, convenient use, low noise and flexible operation, so it occupies a dominant position in the market. [0003] The characteristics of this driving mechanism composed of a motor and a motor driver largely determine the operating performance of this type of mechanical equipment such as operating speed and operating position accuracy. The operation control of this type of mechanical equipment is related to its load characteristics, that is, unde...
