Development of three axes rubber testing machine using electromagnetic linear actuator

Abstract

In general, rubber testing machine is used for rubber strip or product test. Rubber testing machine having technological improvement in the previous three axes rubber testing machine is developed for rubber product test. Rubber product such as vehicle engine mount required to have performance test data over 200 Hz. But, previous hydraulic three axes rubber testing machine can be generate actuating signal of 80 Hz by property of hydraulic actuator. In this work, three axes rubber testing machine having actuating signal of 1000 Hz is developed by adoption of electromagnetic linear actuator in steady of hydraulic actuator. Developed rubber testing machine is verified by performance test.
