| Abstract: | Hydraulic Lash Adjuster （ HLA ） is the main and key part of automobile engine, a kind of leaked-down test system done to HLA is designed.The test platform which consists of Programmable Logic Controller（PLC）, touch screen servo driver and motor is set up. Modularization is adopted for the design of PLC program and the touch screen is configured by using the configuration software. The connection between PLC and touch screen is established via the system. The application result shows that the leaked-down test system has good interactivity and flexibility and the whole testing process is stable and reliable to achieve the desired purpose. |
