Second Generation Load Stability Sensor Device

摘要

A previous study investigated the feasibility of a device to monitor the stability of material handling equipment (MHE). A mathematical description of stability--known as the Stability Index--was developed. A methodology for determining the Stability Index on conventional counterbalance lift trucks was devised. In addition an exploratory system was fabricated for demonstration and examination of the concept. It was found that a microcomputer-based device for monitoring stability of these vehicles is feasible. This study attempts to refine the concept. The mathematical theory was expanded to incorporate non-horizontal surfaces. The relative importance of the various terms was examined via sensitivity analysis techniques. A new microcomputer-based device which implements this new theory was designed, fabricated and tested. A test program was conducted to verify correct operation and to validate the concept. (Author)
