Abstract
An actuator system includes a motor, a ballscrew assembly coupled to the motor, a no back brake device coupled to the ballscrew assembly, and a sensor coupled to the ballscrew assembly. The sensor is configured to acquire load data regarding a load applied to the no back brake device. A control module is configured to determine an estimated coefficient of friction for the no back brake device based on the load data, and transmit an alert signal based on determining that the estimated coefficient of friction is outside a predetermined range. The control module is coupled with the sensor and includes a processor coupled with a non-transitory processor-readable medium storing processor executable code.
Claims20
An actuator system, comprising:
- a motor;
- a ballscrew assembly coupled to the motor;
- a no back brake device coupled to the ballscrew assembly;
- a sensor coupled to the ballscrew assembly and configured to acquire load data indicative of a load applied to the ballscrew assembly;
- and
- a control module coupled with the sensor, the control module including at least one processor coupled with a non-transitory processor-readable medium storing processor executable code for causing the at least one processor to:
- determine an estimated coefficient of friction for the no back brake device based on the load data;
- and
- transmit an alert signal based on determining that the estimated coefficient of friction is outside a predetermined range.
A control system configured to monitor a condition of a no back brake device, comprising:
- a control module including at least one processor coupled with a non-transitory processor-readable medium storing processor executable code for causing the at least one processor to:
- receive load data from a sensor indicative of an external load applied to a ballscrew assembly coupled to a no back brake device;
- receive motor data regarding a motor coupled to the ballscrew assembly;
- determine a coefficient of friction for the no back brake device based on the load data and the motor data;
- and
- transmit an alert signal based on determining that the coefficient of friction is outside a predetermined range.
