Diploma thesis for HTL: simulation program for hammer signal evaluation
Hydraulically or pneumatically operated decoring hammers with an operating frequency of ten to sixty hearts are used to decore castings. To reliably monitor the decoring process, an analog signal is transferred to a B&R controller using a pressure transmitter. The frequency of the raw signal is evaluated in this controller. In order to test these monitoring units in series production, it is essential to use a mechanical setup of the hammers or pressure transmitters and to test various settings in a practical test.
The aim is to avoid the effort for the mechanical setup and the test under real conditions by using a simulation box. The raw signal of the respective hammer sensors (analog signal) must be recorded and analyzed once. This data serves as the basis for simulating the analog signal of the hammers. For this purpose, a B&R controller must output the previously recorded raw signals via an analog output. The controller thus functions as a virtual hammer.
Furthermore, the correct evaluation of the analog signal at the partner controller (hammer monitoring) is to be monitored using a feedback loop.
