关于客户
Hutchinson Technology Inc. 的磁盘驱动器组件部门是磁盘驱动器悬架组件的全球制造商。作为业界唯一的垂直集成悬架供应商，该公司处于有利地位，能够提供磁盘驱动器制造商当前和未来产品所需的快速原型设计、批量生产速度、高水平的质量和最低的总体成本。该公司旨在满足客户对速度、容量和可靠性日益增长的要求，并保持其在生产复杂悬架总成方面的市场地位。
挑战
Hutchinson Technology Inc. 是一家全球磁盘驱动器悬架组件制造商，该公司在硬盘驱动器磁头悬架组件的运动精度方面面临着重大挑战。气流引起的振动增加了滑块位置的不确定性，这对于磁盘的数据传输至关重要。这个问题在高速驱动器中尤为严重，因为气流振动强烈，降低了磁头组件的精度。此外，在高面数据密度驱动器中，数据磁道间距非常细，小的悬架振动可能会显着降低驱动器性能。该公司的目标是满足客户对速度、容量和可靠性日益增长的要求，并保持其在生产复杂悬架总成方面的市场地位。
解决方案
Hutchinson Technology Inc. 利用 ANSYS Fluent 和 ANSYS Mechanical 仿真软件来应对这些挑战。该软件成功地根据简单驱动器中的流量实验数据进行了基准测试。 Fluent and Mechanical 仿真软件用于计算以 10,000 rpm 速度运行的 3.5 英寸实际硬盘驱动器中的流固耦合 (FSI)。该仿真用于识别驱动器内的涡流脱落，这在引起振动方面发挥了重要作用。该团队发现，重新设计某些组件可以避免操作过程中的涡流脱落，从而减少振动并提高头部位置的准确性。磁头的这种精确定位可以实现更小的磁道间距，从而实现更高的面积密度。

Green Planet Case Study
Ztech supplies turbine flow meters to one of the largest water utilities in Gujarat, there utility customer wanted them to provide real-time connectivity between their software and the water meter. They were also getting enquiry for a smart water meter from a lot of their existing customers too. One of their competitors had already launched its smart meter solution. They were short on time to launch such a water meter. Ztech wanted results in few weeks instead of months. They already had an water metering application but that was only designed for manual entries or hand held equipments.
