Abstract

This study introduces an innovative method for testing the durability of linear actuators using compression springs in a reciprocating motion. The method applies a resistive load to the actuator for a number of cycles, simulating its operational environment. The method is notable for being cost-effective to produce, easy to operate, and characterized by minimal complexity and few moving parts. The load is quantified through a combination of load cell measurements and a precision weighing controller, while the theoretical load is derived from spring specifications and electric current data from the actuator’s software controller. Comparative analysis between the empirical data and FEA results demonstrates the accuracy and versatility of this testing method. This approach allows for customizable resistive load adjustments, ensuring that linear actuators meet stringent standards and specifications prior to deployment. The integration of both empirical measurements and FEA provides a robust framework for assessing actuator durability and performance.

执行机构耐久性测试的机械方法：压缩弹簧系统的设计与实现

本研究介绍了一种创新的方法来测试在往复运动的压缩弹簧线性执行器的耐久性。该方法在执行器上施加一个电阻负载，以模拟其运行环境。该方法的显著特点是生产成本效益高，易于操作，并且具有最小的复杂性和很少的运动部件。负载通过称重传感器测量和精密称重控制器的组合来量化，而理论负载则来自执行器软件控制器的弹簧规格和电流数据。实验数据与有限元分析结果的对比分析证明了该测试方法的准确性和通用性。这种方法允许可定制的电阻负载调整，确保线性执行器在部署之前符合严格的标准和规范。经验测量和有限元分析的集成为评估执行器的耐用性和性能提供了一个强大的框架。
