ED-HALT (6-MDoF)– an introduction KING DESIGN INDUSTRIAL Co., LTD / Since 1983 Dr.Richard Lin / David Lee-CEO rich.lin@kdi.tw / davidlee@kdi.tw
Three key factors to enter the primacy market Client needs Reasonable price The right time
Three key factors to enter the primacy market • Client needs— • Function / Performance / Maintainable / Reliable / • Dependable / User Friendly • Reasonable price—More Cheapen • The right time– • More eariler / when I need , it need come out ! Intel core-8*
Because of you care? Why we need Quality ?
To match customer required is true quality ! But also the economic and environmental
Quality -Usually contain-- Functional, Performance, Safety, Reliability and a sense of Quality… and it should be compliance with Government Regulations and International Economic Trends in the Market and so on. Quality is a general term
Needs include: Performance, use Economy.., Dependability (including Availability, Reliability, Maintenance degrees) Security, Social Environment and Economy as well as the level of Aesthetics Performance: The functions are easy to use Time: operation time, degradation time → Durable Environment: Waste Reduction, Can Recycling → Environmental Conservation Economy: Research and Development costs, Manufacturing costs, Quality costs, Operating costs →Save Money Maintenance →MTTR→ Save downtime and Repair money→Maintainability+Supportability+Measureabilty(Testability) Needs should include ?
Needs should converted to the specified characteristics with the requirements and guidelines of the specification. Needs will change because of time frame, so the demand for Quality must be Regularly Revised to match people required.
Process of Quality History Quality is Inspection/Checking out.. Quality is Manufactured.. Quality is Designed in.. Quality is to meet customer needs --Tangible and Intangible
Reliability technology development process Reliability ? Reliability + Maintainability Reliability + Maintainability + Supportability Dependability Dependability + Safety --------Trustable---
Innovation / Create vs. Quality /Reliablity . ..It always around us.Innovation new issue most of time can let us feel surprise and happy .It’s a kind of Alternative Quality !
ED-HALT • The world first–6 DOF random, compact Electro-Dynamic(ED) drive repetitive-shock(RS) vibration system. • Contain high low-frequency vibration energy. • Adjustable impact force (time, amplitude, phase, and vector) • 2nd Generation of HALT – innovate product KING DESIGN
ED-HALT vibration table control • For 12”, 18”table,table is divided into 4 sections of control zone • For 20”and above,table is divided in 9 or 16 and more mode to fit any sections • Each control zone with 5 ED impactors • Improve table vibration - uniformity, controllability, repeatability • tunable frequency range KING DESIGN
Precise synthesis force vector in any direction and magnitude • ED-HALT can synthesis force vector in any direction, magnitude (by adjust the current, , timing, phase and impact frequency of ED impactor) • Can use to produce excitation to specific mode • Random mode • Low frequency vibration Energy (below 1,000Hz, effective energy to precipitate fatigue failure mode ) Force vector (any direction, magnitude) KING DESIGN
Technical Evolution: S Curve Key parameter (low frequency vibration energy) Air HALT Air pressure High frequency SRS with Low Frequency vibration Target Fundamental limit To meet the target, system need different kind of change: Air Voltage, current, Phase (controllability) • Low frequency,adjustable spectrum • 6-MDoF • Closely Spherical Stress • Tailor to failure mode ED-HALT 2nd Gen system ED-HALT Control current and timing • Medium Low frequency vibration with High Frequency Response Exist system 1,000 2,000 4,000 KING DESIGN
KD value proposition People concern those who would like to find potential failure mode quickly in RD stage Who are satisfied with currentHALTand shaker? Kdi product is a ED-HALT– innovative 2nd generation HALT can provide Air HALT cannot do! (it after 35 years later) That provides Highly/ Middle-Low frequency FDS and SRS /PSD in to the device and system. Up 3-factors FDS are first priority key to detect default!
4 control zone table design Each units are combination with 150SQ~300SQ~400SQ KING DESIGN
9 control zone table design Each units are combination with 150SQ~300SQ~400SQ KING DESIGN
ED-HALT advantage • Compare with traditional HALT • Middle-Low frequency vibration energy,PSD, FDS / ED-HALT is more better • Compare with traditional shaker • 6 DOF vibration,ED-HALT also more and more better • FDS relation with product life • Miner’s law: acceleration factor for product life estimation
Fatigue curve • Fatigue failure mode: material physical limit • SN curve As in diagram: X material limit KING DESIGN
Customer key problems • Customer demand high reliable product (key parameter) (better! faster! cheaper!) • High reliable product need more time to validate the reliability • Competition pressure (fast!) • Product life reduced, demand shorter RD cycle not enough time for long reliability test • ED-HALT • Step stress Highly accelerated test • In RD stage, quickly find the potential failure mode and fix • Find the margin (operation limit, destructive limit, design spec) • For mass production–HASS • FDS and life relationship • Estimate the product life consume for screen stress
Miner’s Law: fatigue Miner’s Law: cumulative damage index (CDI) : n i cycle number at stress i N i fatigue cycle number at stress i m bin of different stress level Theoretically , failure happen whenCDI=1.0 KING DESIGN
Why high frequency vibration energy did not cause fatigue • The probability of high frequency energy is not high, except at impact and Shuttle launch • The transfer function between the impact and fatigue site, basically is low pass filter, high frequency energy is absorbed • Fatigue is due to stress and strain, the amplitude of high frequency is small, the fatigue damage D(ni/)=0, the stress below elastic limit, the fatigue cycle is limitless()。 KING DESIGN
Air HALT structure and control Vibration table: many air impactor Air impactor
Air HALT impact response The acceleration and frequency is depend on air pressure, the higher the air pressure, the acceleration and frequency increase。 modulation ↑ Impact frequency, acceleration vs air pressure Acceleration at different air pressure
FDS at user environment • Different devise in user environment • Different from HALT PDS HALT-HASS Vibration Demystified, Stephen A. Smithson
