Simulation Calculation of the Braking Performance of Portal Cranes Based on ADAMS

Abstract

The braking performance of open-air crane is essential to safety. Taking 40t Portal crane as the study object, this paper first analyzed and calculated the braking torque of traveling mechanism according to the design rules for cranes. Then the portal crane traveling mechanism model was established by the use of simulation software ADAMS, the braking process of crane of constant wind load was studied on typical operation conditions, and its braking performances were comparative analyzed. Finally, it can be concluded that it will substantially increase the crane braking time and braking distance after braking torque is adjusted small and cause hidden troubles of accident. The analytical method and conclusions of this paper can provide a theoretical basis to crane safety management.

Simulation Analysis of Portal Crane Braking Effect with Dual-Stage Brakes under Fluctuating Wind Load

“…The wind load mentioned above is a constant design value, however, it is fluctuating actually. In order to analyze the braking effect of crane accurately, the wind should be simulated as fluctuating load, which can be found in reference [4] in detail.…”
