ELECTRONICS UNDER SEIGE IN RADIATION CHAMBER
KISPE Space Systems in Farnborough is collaborating with the University of Surrey on a programme of comprehensive proton testing for its microsatellite platform microelectronics systems. These tests will enable the company to
continue developing the platform and drive forward the commercialisation of the microprocessors for future, low-cost small-satellite missions. Following on from a previous project
undertaken with the Surrey Space Centre (SSC) at the University of Surrey, the new project will be co-funded by KISPE and a £5 million grant from the SPRINT (SPace Research and Innovation Network for Technology) programme that provides unprecedented access to the university’s space expertise and facilities. Such facilities include the REEF radiation chamber, which is used for bombarding the electronics with protons. According to Dr John Paffett of KISPE
Rather than choose a traditional roller
dyno, Burlen has installed a Dynapack chassis dynamometer, a modular system which couples to the wheel hubs and applies a precisely controlled hydraulic load. This method eliminates tyre slip, offers
no rolling resistance, and ensures there is no chance of the vehicle coming off the dyno at high speeds. Direct coupling also provides improved sensitivity and repeatability which significantly reduces time needed on the dyno.

Space, the company wants to ensure that its electronics are robust. “This new SPRINT project with the University of Surrey team will position us to extend our knowledge of how these low-cost microprocessors perform in a representative space environment,” he says.

VIBRATION ANALYSIS FOR BOARD ROLLING MILLS
Finnish heavy process machinery specialist Valmet will provide roll maintenance and condition monitoring services to Shanying International at the company’s Anhui mill in China. The services cover roll grinding,
recovering and reconditioning, roll condition monitoring and vibration analysis for five board machines together with on-site investigation and Valmet Industrial Internet remote analysis and diagnosis.
Using the condition monitoring services,
medium, such as aluminium honeycomb, to offer a tuned deceleration pulse. Engineers can log myriad data points including temperature, acceleration and impact velocity as well as live CAN data from the test item.
Shanying expects to see increased roll lifetimes with significant reductions in unplanned downtime and roll regrinding. “The extensive mill personnel training
that’s been undertaken supported by our vibration experts via a secure data connection makes full use of the mill’s roll
condition monitoring systems,” says Shiming Xu of Valmet China. “The service agreement will ensure a high level of equipment maintenance and management.”
DNA Machine Monitoring collates machine and roll condition information for process operators and maintenance personnel through one common user interface. Operators are immediately alerted if
there is a risk of machine/roll failure and indicators of roll condition, while the paper machines are running, are easily analysed. A secure Valmet Industrial Internet
remote connection allows Valmet experts to provide an agreed level of remote diagnostic support for machine problems and roll maintenance decisions.
