引言前些年,曾多次出现锚机制动系统的误差,特别在超级油船上,这些误差造成锚和锚链的损坏。在抛锚时,由于锚和锚链重量大,其相应动能和势能也大,制动时必然转换形成较高的热能。这个过程会使制动块产生不允许的温升,并且引起所谓的“热衰退”现象。随之制 INTRODUCTION Errors in the braking system of the anchor windlass have occurred many times in previous years, especially on the super-tanker, which caused damage to the anchor and the chain. When anchored, the corresponding kinetic energy and potential energy are also large due to the heavy weight of the anchor and the anchor chain, which inevitably transform to form higher heat energy during braking. This process causes an unacceptable temperature rise in the brake pad and causes a so-called “hot recession” phenomenon. Followed by the system
