Alghamdi1 1Mechanical Engineering Department, College of Engineering, University of Ha’il, P.O. Box 2440 Ha’il, Saudi Arabia 2Central Metallurgical Research and Development Institute (CMRDI), Cairo, Egypt Correspondence: Abdulaziz S. Alghamdi ([email protected]) Received: 24 March 2020 – Revised: 10 August 2020 – Accepted: 11 September 2020 – Published: 27 October 2020 Abstract. The bimetal casting process using the liquid–liquid technique was developed to produce a high- quality hyper-eutectic Al–21Si / hypo-eutectic Al–7.5Si alloy bimetal material. Microstructure and microhard- ness were investigated as a function of the time interval between pouring hypo-eutectic and hyper-eutectic alloys. A bimetal material was successfully fabricated using a liquid–liquid casting technique with a 10 s time interval in a permanent mould casting. A unique structure comprised of hyper-eutectic Al–21Si, hypo-eutectic Al–7.5Si and a eutectic interface of 70 µm thickness was obtained. This structure totally differs from that obtained using a higher time interval above 10 s that showed an imperfect interface bond due to the shrinkage cavity and formation of oxides. The hardness variation from the upper zone of 117.5 HV to the lower zone of 76 HV corresponded to the variation in Si and the content of other alloying elements. -

FITTING INSTRUCTIONS TO SUIT CHRYSLER VALIANT V8 PACEMAKER HEADERS part no PH 2535 IMPORTANT: To fit column change automatic, linkage modification is necessary. Gearbox rod must be cut and loop inserted on top of header pipe. FIT RIGHT HAND SIDE (drivers side) FIRST 1) Disconnect battery and remove plugs. 2) Undo brake power booster and move out of the way. It is also advisable to remove rocker cover to save from scratching and it also improves the working space around the engine. 3) Remove cast manifolds and rear stud and clean head surfaces. 4) Undo and remove centre drag link 5) Remove right hand engine mount bolt from underneath car. Loosen left hand side engine mounting but do not remove bolt 6) Jack up engine as far as possible and from underneath place header into engine bay. 7) Using silastic on face of header and gasket, bolt header to head but leave loose. 8) Gently lower engine back into position, making sure header dose not become jammed. 9) Once engine is lowed, replace engine mount bolt and tighten both bolts up and relocate drag link. 10) Finish drivers’ side by tightening up header, and replacing brake power booster and rocker cover. TO FIT LEFT HAND SIDE (passenger side) 1) Remove pollution canister and cast manifold, and clean head surface. 2) Unclip kickdown lever from back of gearbox to allow header into position. 3) Place header into engine bay from the top using silastic on header face and bolt up tight 4) Clip linkage back on kick down, and bend canister bracket to clear last header pipe. -

These parts can include a On some vehicles brake drums are an alternative system master cylinder, brake fluid, hoses, calipers, brake pads, (generally older design and predominantly on the rear). rotors, drums, and brake shoes. The ‘drum’ sits at the wheel hub and rotates along with the wheel.

HYDRAULIC PRESSURE DISC BRAKE ROTORS / PADS Regardless of the type of system, both are actuated through hydraulic pressure. When pressing the brake Today’s modern vehicles generally come with brake pedal, hydraulic pressure is built up in the master rotors/pads assemblies. Brake rotors are large, rotating, cylinder that sits within the vehicle’s engine bay. This circular cast iron plates fitted into the wheel hub. When hydraulic pressure is transferred through a series of engaging the brake pedal, calipers that sit around the pipes and hoses to the front and rear brake calipers, rotors are moved inward and force the brake pads which then engage the brake pads or shoes and against the rotors. -

Improvement of Shaped Charge Penetration Capability and Disturbation of the Jet by Explosive Reactive Armor
ISSN 1330-3651 (Print), ISSN 1848-6339 (Online) https://doi.org/10.17559/TV-20190216141334 Original scientific paper Improvement of Shaped Charge Penetration Capability and Disturbation of the Jet by Explosive Reactive Armor Hicham KEMMOUKHE, Zijah BURZIĆ, Saša SAVIĆ, Slavica TERZIĆ, Danica SIMIĆ, Miodrag LISOV Abstract: This paper presents a numerical study of the effect of main parameters (liner material, explosive charge, stand-off distance and the presence of the wave-shaper), on one hand, on the jet formation, jet velocity and the jet length, and on the other hand, on the penetration depth. We propose a numerical approach to evaluate their effects on the performance of the shaped charge. AUTODYN-2D software is used for numerical simulations of the shaped charge. The multi material Euler solver of the AUTODYN is used for the jet formation investigation, whereas, Lagrange solver is used for the resolution of the penetration problem. Results have shown that the presence of wave- shaper increases the shaped charge depth penetration. For the standoff of 6 charge calibres, the jet penetration is found to be deepest. It is found that the jet velocity is proportional to the jet energy, and the penetration is proportional to the liner density. The oblique explosive reactive armor is more efficient for the protection of the main target. Numerical results have a good agreement with the data from available literature – with experimental results for the chosen explosives. Keywords: ERA; HEAT; high explosive; metal liner; wave-shaper 1 INTRODUCTION wave shaper which overlaps the liner.
